The following list of British Patents which have been granted in favour of residents of Germany, Austria, or Hungary, is furnished in view of the new Patents Acts, which empower the Board of Trade to confer upon British subjects the right to manufacture under enemy patents, and is specially compiled for the Colliery Guardian by Lewis Wm. Goold, Chartered Patent Agent, 5, Corporation-street, Birmingham. It is desirable in the first instance to obtain the latest particulars upon the Register of Patents. If any patent listed has been assigned to a non-enemy proprietor, the law does not apply. 14273/08. Mine props. Relates to walling, timbering, and propping mines. Two semi-tubes, one of which is divided, are connected together by rings, one ring being placed at the joint of the two parts when the prop is in use. Peat fibre is placed at the bottom of the prop, which is then partly filled with granulated rock, a space being left at the top of the prop for a wooden plug, recessed at the top to take a semi-cylindrical iron cap between which and the roof are placed layers of peat, so as to allow room for the lagging. To remove the prop the ring which has been placed at the joint is displaced, and the prop struck with a hammer, whereupon some of the rock escapes, thus allowing the plug and cap to sink. F. Nellen, Germany. 1876/12. Mine props. Relates to mine props described in the parent specification, and consists in com- pressing the filling material by screwed spindles engaging in nuts on the upper members of the props. The filling material is compressed after the erection of the prop, in order to modify the elasticity of the prop and to avoid hollow spaces. F. Nellen, Germany. Addition to 14273/08. 2398/12. Pumps. Pumps with reciprocating and oscil- lating pistons. A pump for viscous liquids is provided with a cylinder liner, which by its oscillation acts as a valve. E. Nack (Nach- f olger), Germ any. 2466/12. Hoists. A hoist is provided with two shafts, slidable in opposite direction, and carrying gearing so that a slow raising or a fast lower- ing speed is imparted to the hoisting shaft. 0. Gehricke, Germany. 2862/12. Carbon. Carbon masses capable of absorbing gases, condensing the same, and communi- cating them to other substances, are obtained by heating in a vertical retort a suitable carry- ing material, with a material capable of evolving gases containing carbon; the upper part of the retort is maintained at a compara- tively low temperature, the middle part is heated to incandescence, and the lower part is cooled., the temperature of each part being maintained practically uniform throughout, whereby the distillation gases evolved in the middle part deposit carbon upon the carrying material in the upper and lower parts.

Schlich, Professor of Forestry at Oxford, writing in the Quarterly Journal of Forestry on “ Forestry and the War,” refers to the enquiry made by the Board of Agriculture into the supplies of pit- wood for the collieries of this country, the result of which was that it was ascertained that 7,900,000 tons of pitwood existed in England and Wales, and 3,800,000 could be made available by extraordinary fellings. The latter quantity would meet the requirements for one year, while the total existing quantity would be used up in the course of two years, in both cases exclusive of stocks and future imports. As regards imports, it was ascertained that during September last the actual amount came to 240,000 tons, whereas the normal September imports of former years came to 600,000 tons. The larger part of the September imports came from the west coast of France, in fact, from the Landes. The imports from the Baltic were quite insignificant since the war commenced. We may well ask, Sir William says, what would be the position if the war should last more than two years, and what will be the effect on British woodlands at the end of it. Just imagine our position if half our coal mines, or even more, had to be shut down for want of pit- wood. Why, the whole country would be ruined! Sir William points out that had woods been planted in Great Britain and Ireland 30 years ago our position would have been quite different now that unexpectedly this war has placed us in a very serious position as regards pitwood, not to speak of telegraph poles, building timber, and even fire- wood. The financial aspect of afforestation had been placed too much into the foreground, and it had been forgotten that there may be other considerations of great importance for the welfare of the people and the State as a whole. Sir William Schlich considers it the bounden duty of the Government of this country to take early steps to increase the area of the forests in these islands. There is plenty of surplus land available now yielding a revenue of perhaps Is. an acre all round, if so much. There are large stretches of land unfit for cultivation, and yet quite fit to produce forest crops. GOVERNMENT PUBLICATIONS.

The plaintiffs, Messrs. Booth Brothers, of Pancras-road, sued Mr. Egan, of 11, Warwick- street, S.W., to recover £2 4s., the price of two tons of coal. Mr. Cartwright, solicitor for the plaintiffs, said that when the coal was sent out there was a delivery note stating that the printed receipt provided by the plaintiffs was the only valid one. When the coal was delivered the delivery note was signed by the defendant’s wife. Later the defen- dant paid a person who was not entitled to receive the money. Mr. W. Firman, the plaintiffs’ representative, said he called on the defendant, who said he had paid the plaintiffs, and produced a receipt which witness told him was not a valid one. The receipt was on the top of a memorandum form, and had been given by an agent who was not in their employ, and not authorised to receive pay- /nent. An account was sent after the coals had been delivered. The order was given to an agent, and he signed it, and sent it to the plaintiffs, and later collected the money. A carman in the plaintiffs’ employ stated that when the coal was delivered a note was handed to the defendant’s wife, and she signed the receipt. His Honour Judge Bray said he must hold defendant liable, and made an order to pay 10s. a month. He also expressed the opinion that coal merchants should send some acknowledgment to customers as soon as orders were received. If the acknowledgment was sent to a customer as soon as an order arrived, it would act as a warning to a customer to pay the proper person. Oxygen Resuscitating Upptotus The Safest and Most Reliable Means of reviving persons apparently asphyxiated is to administer Oxygen by a simple form of apparatus, as shown, and at the same time use the Schafer method of resuscitation which is known to all St. John Ambulance and Red Cross Students.
