764 THE COLLIERY GUARDIAN. April 20, 1917. these analyses, he was prepared to back the opinion of his staff against all comers. If that pricker of Mr. Tate’s would assist them, and help the deputies, Mr. Tate would have done an exceedingly good day’s work for the coal mining industry. Through Mr. Tate’s kindness, he had been enabled to try that pricker in a safety lamp in several percentages of gas; it fulfilled all that Mr. Tate claimed for it, and should prove exceedingly useful. As to the Davy lamp, Mr. Wilson said, in conclusion, it was not a prescribed lamp, but it was distinctly a proscribed lamp—whether disguised in a tin or in any other form. Col. Blackett said that a lot of little contrivances such as that pricker reminded him of midges — they flew around for a few sunny hours, and then they vanished for ever. A few years ago he flattered him- self that he had brought out a useful little contri- vance, in the shape of an apparatus for shielding the flame of a lamp from the sight so that the cap could be readily seen. He brought it before the institute, and it was approved in a kind-hearted sort of a way— and then it vanished. It was based on the sound prin- ciple that the hotter the flame the bigger would be the cap. It obscured the flame in pretty much the same way that the pitman had been in the habit of obscuring it with his thumb. After a little further discursive discussion, Mr. Tate briefly replied. Timber in Coal Mines. A paper on “ Some Practical Notes on the Use of Timber in Coal Mines ” (p. 761) was read by Mr. ±. C. Lee. Discussion. The Hon. Secretary (Mr. M. W. Parrington) remarked that the paper, coming at such a time, was worthy of very serious consideration and of discussion at a future meeting. The conditions under which Mr. Lee had written his paper were probably about aver- age. There were, however, members interested in it, some of whose collieries were shallow, whilst others were deep, and conditioned entirely differently. Col. Blackett said that at present systematic tim- bering wanted very careful consideration on the part of the Government, and he would put it to Mr. Wilson- (H.M. inspector) earnestly to consider whether he could not, at next meeting, give them some moral views on that particular subject. The speaker was not going to suggest that systematic timbering was wrong —there was systematic timbering and systematic tim- bering. The instances given by Mr. Lee belonged to one set, but there were others which were not of the same importance. It was one thing to put in row after row of timber to control the fall of the roof and to see that it behaved itself properly, but it was a totally different thing to make men shove timber into places where it was not required and where it would never be any real use. They put timber in bord after bord, headway after headway, according to law, when their common sense told them that it was not neces- sary for safety. In these days when timber was so scarce, he thought it was worthy of every considera- tion that, where systematic timbering was not actu- ally conducive to the safety of the mine, the rules as to the putting in of timber at intervals of so many feet should be re-considered. Mr. Lee was very cordially thanked for his paper, and the discussion was adjourned. A New Syphon. Mr. S. F. Nicholson’s paper on “ The Horsley and Nicholson Automatic Compound Syphon ” (p. 766) was read. Col. Blackett described the syphon as a most excel- lent device, which would do what Mr. Nicholson claimed for it. It was an appliance well worth putting into pits. After a very short discussion, the meeting ended. Partnerships Dissolved.—The London Gazette announces dissolution of the partnership of J. Burgess and G. Law, trading as the Cleveland Forge Company, 50, Duke-street, Birkenhead; of J. W. Bennett (who continues the busi- ness) and E. G. Bennett, trading as B. and J. Bennett and Company, carriers and coal merchants, West Cross, Tenterden; and of H. G. S. White and W. Cash, trading as White and Cash, engineers,. Mount-street, Walsall. Wigan Mining College Summer Course. — It has been decided to hold short summer courses of about 10 weeks’ duration in connection with the mining department of the Wigan and District Mining and Technical College, and particulars of these have been issued by Mr. S. C. Laws, M.A., B.Sc., the principal of the college, a start .in this direction having, in fact, been made during the present week. In practical surveying, there will be a day course meeting on Tuesday from 9 a.m. to 4.30 p.m., commencing on Tuesday last (April 17), as well as an evening course on Thursdays from 6 to 8.30 p.m., commencing on May 10, the fee for the former being 10s. and for the latter 5s. ; while in mining geology, a class will meet on Tuesday evenings from 6 to 8.30, commencing on May 1, and 5s. will be the fee. In addition, there are to be colliery fire- men’s courses, and day classes for colliery firemen will be held on Thursdays from 9 a.m. to 12 noon, commencing on Thursday this week (April 19), while evening classes are to be held on Monday evenings from 4.30 to 7 p.m., the initial evening class dating from Monday evening of the present week (April 16), but the hour for this latter class will, the principal announces, be altered if necessary after the first meeting to suit the convenience of students. At the conclusion of the courses for colliery firemen, an examination will be held for colliery firemen’s certificates. WAYLEAVES.* By C. Vernier, So long ago as 1905, when Mr. G. L. Addenbrooke read a paper entitled “ The Value of Overhead Mains for Electric Distribution in the United Kingdom,” references were made to the difficulties which were then being experienced, and which it was anticipated must inevitably be experienced in a greater degree as the use of overhead mains tended to become more general. In this paper some particulars were also given of the admirable legislative provisions afforded for the erection of overhead and underground mains on private property in Italy and Switzerland. During the 12 years which have since elapsed, the need for such facilities has become more and more insistent. Electric power supply was then in its infancy, and although between 1,000 and 2,000 route miles of overhead electric mains have already been erected under the difficult conditions at present obtain- ing in this country, the time has come to consider seriously whether the important services which public suppliers of electrical power, light, and heat, must continue to afford—and certainly in a greater measure than ever before — to our industries, manufacturers, railways, and the practically untouched field of agri- culture, in the strenuous and difficult times which will follow the present European conflict, do not call for prompt legislative assistance in removing certain diffi- culties that at present hamper their fullest develop- ment. The need for efficiency and economy will be so seriously accentuated, both in regard to a more effi- cient utilisation of our seriously depleted capital, and also in regard to the conservation of our natural resources, of which in this country coal is unquestion- ably the most important, that there is every reason to expect that electrical services which can so eminently achieve both these objects will be sought for to an unprecedented extent after the war. It will be sufficient to state that on 20,000-volt mains the saving .in capital cost which can be effected over an equal length of route by the use of overhead wires as against the use of underground cables is in the neighbourhood of 50 per cent., excluding the cost of way leaves in each case. At higher voltages it is yet greater; while by using cross-country routes for under- ground mains, instead of keeping strictly to public roads, a saving in capital cost of 30 per cent, is not uncommon on routes of several miles, and even more on shorter lengths, as the result of shortened routes and cheaper reinstatement of the ground. It must further be borne in mind that although the Board of Trade are willing to allow extra high-pressure over- head lines on public roads, subject to strict require- ments regarding public safety, practical considerations usually render this, if not quite impracticable, at least extremely undesirable, and therefore all such lines must ordinarily be placed on private property. There is, also, the probability that, in the near future, much higher transmission pressure will be employed, and this cannot in the present state of the art be satis- factorily dealt with (if at all) by underground cables. Consents.—In considering the clauses of the Electric Lighting Acts, 1882, 1899, it is necessary to differen- tiate between the various classes of undertakings, viz., statutory municipal and statutory company undertakers and non-statutory undertakers. The above Acts compel statutory undertakers to obtain the consent of the local authority to the erection of overhead mains everywhere outside their own premises. This consent is obviously unnecessary in the case where a local authority are themselves the undertakers, supplying only within their own district, and such consent in the case of a local authority would only be required in the exceptional case of a municipal undertaking wishing to erect overhead wires for giving a supply outside the area scheduled in the Order and in the district of a neighbouring local authority under powers conferred by section 6 of the Electric Lighting Act, 1909. For a statutory company undertaking, the con- sent of the local authority is in every case essential, and further, there can be no appeal from the decision of a local authority in this matter, which may refuse its consent without assigning any reason, or may attach unreasonable and onerous conditions thereto, or cause unreasonable and vexatious delays. There is only one usual exception to this procedure, i.e., in the case of the Power Acts, where an appeal to the Board of Trade is allowed in the event of a consent by a rural district council being unreasonably withheld. The anomaly of the position will be better appre- ciated when it is pointed out that any private indi- vidual or company who cares to undertake the trans- mission or distribution of electricity without statutory powers—which can be and is commonly done, for example, by colliery and quarry owners and others, as there is no restriction placed upon it so long as elec- tricity supply to consumers is not the chief business of the undertaker — is perfectly free to erect overhead wires over private land without the consent of the local authority, and can quite well carry such wires across public roads and footpaths, provided the local authority are not the owners of the land on either side of the road, and that care is taken not to contravene any by-laws which the local authority may have adopted, and further, in the absence of special by- laws that the highway is not itself interfered with or broken up, and that its ordinary use is not restricted in any way. Many local authorities have but the haziest idea of why they stand possessed of the powers conferred in the clauses of the Acts already quoted. Some, and * Abstracted from a paper read before the Institution of Electrical Engineers, Thursday, April 12, 1917. fortunately a good proportion of these local authori- ties, treat the matter as a mere formality to be com- plied with by the undertaker, and consent readily; others, as we have seen, in the absence of proper enlightenment, usurp functions which properly belong to the Board of Trade; while in other cases it is diffi- cult to discern the existence of that public spirit which one might look for in the representatives of an impor- tant community. It is essential that a right of appeal to the Board of Trade should be allowed in all cases, and that while the local authority should have the right to be heard, it should have no absolute veto on such questions, and that all powers of interference in technical questions, such as design and questions of the public safety, with- out a reference to the Board of Trade, should be abso- lutely taken from them. A time limit should further be determined, say, one month, as in the case of works on public roads, during which a local authority must either signify or refuse its consent, failing which such consent will be deemed to have been given, as the unreasonable delays which are at present possible in some cases should not be tolerated. If there be any insuperable objection to extending the right of appeal in the somewhat special case of county boroughs, it should nevertheless be applied to urban district councils, as well as to rural district councils. Many urban areas, at least in industrial districts, partake of the character of rural districts in their sparsity of population, and quite a large part of an industrial county, and often just that part where over- head wires are most needed, may comprise a number of contiguous urban areas. ' Wayleaves.—Electricity supply, also gas and in some cases water, undertakers are precluded by law from laying their mains in private lands without special consent, and this is only possible by a complete agree- ment for an easement or wayleave with the owner and occupier, and upon such terms and conditions as he or they may in their entire discretion impose upon the undertakers. The above restrictions have been found to be a source of serious inconvenience and unnecessary expense, and a hampering obstacle in the development of electric power supply on a large scale, and in the full achieve- ment of the economies resulting therefrom. Cases of absolute refusal to grant an easement or wayleave have been fortunately of rare occurrence, but it is otherwise with the imposition by land owners of unnecessarily oppressive conditions, chiefly the exact- ing of outrageously exorbitant rents, having regard to the use which is made of the land and its value to the owner, and with some exceptions in their exercise of procrastination and utter indifference to industrial needs in dealing with such matters. Quoting examples, the author referred to the case of a colliery company owning land in various parts of a district which held up wayleaves in two places on overhead lines some 30 miles long, taking advantage of the opportunity offered to negotiate favourable terms for a supply of electricity to a colliery. This sort of case, he said, was likely to become more troublesome in future, as colliery owners have in recent years adopted the policy of purchasing agricultural land, in order to avoid heavy claims for compensation for damage arising from subsidence from their work- ings. A frequent cause of prolonged delay is that one or more owners, after the usual initial delay in replying, which varies according to the individual, make objec- tion to the route selected over their land. Negotia- tions must then be re-opened with other owners, who probably have already given their consent, to allow of a diversion of the route on their estate, and in conse- quence they not infrequently come to the conclusion that the applicant does not know his own mind, which is not usually conducive to a speedy settlement. If, in addition, a local authority should call for a diver- sion of the route when negotiations with land owners are well advanced, it is readily perceived how delays become cumulative. Cost of Wayleaves.—Compensation for an easement or wayleave is almost invariably given in the form of an agreed annual rent, based either on a fixed sum per pole or per yard of route, or an annual lump sum payment to cover a particular stretch of route between fixed points. Rents have steadily risen during the past seven years, and especially since the war began. This is partly because land owners who at first treated way- leave rents merely as a convenient addition to the rents which they have already received for the ordi- nary use of their land, have more and more come to regard wayleave rents as quite a useful source of addi- tional revenue, and especially since the war scale of taxation came into force, have made the most of their opportunities. Moreover, as it is usually quite impossible to bring the slightest pressure to bear in negotiations for way- leaves, it has in unavoidable cases been necessary to pay some recalcitrant land owner a heavier rent than usual in order to complete wayleaves for a route, the alternative possibly being a diversion of the route on adjoining estates and many more months of delay, or possibly heavy expenditure in circuiting his estate, usually both. Other land owners have come to hear of this rent, and have asked for the same terms. If these charges may fairly be termed iniquitous in the case of overhead lines, what should be said of the same rents which are now frequently asked for way- leaves for underground cables? Underground cables, when once laid, generally require no further attention for many years, and do not obstruct or interfere in any way whatever with the ordinary use of the land;
