September 18, 1914. THE COLLIERY GUARDIAN. 623 In reply to questions in the House Trading With of Commons, on Wednesday, by Sir the Enemy. J. D. Bees as to the legal status of contracts with alien enemies entered into before the outbreak of war, the Attorney- General made the following answer:— Any difficulty which arises in answering the question to which the hon. member refers is not due to any doubt as to the principle to be applied, but to the complexities of each individual case. Conse- quently, a general statement, even if it were universally accepted as authoritative, would not provide a solution, and individuals will find that the only practicable course is to seek competent private advice on the circumstances of their own case. This statement may be taken to answer quite accurately the much larger question of trading with the enemy much larger because it embraces not only past transactions, but future dealings also. The abstract principle is fairly clear; according to Prof. Usher, “the Germans refuse to recognise as moral anything which jeopardises their national existence.” This may be a dangerous doctrine in times of peace, but no one can doubt its soundness under the condi- tions that now prevail ; in a word, trading is not permissible where it is to the disadvantage of this country; and this guiding principle must be applied in a negative as well as in a positive sense; it is not sufficient to show that we derive direct benefit from such trading, for international trading can only exist upon the basis of mutual interest, but it must also be shown that no direct and immediate advantage is conferred upon enemies that may sustain them in their hostile operations against this country. In practice, however, this is a principle which it is singularly difficult to apply; the commercial relations between this country and Germany take so many forms that we must constantly be in the predicament of being unjust, or of being duped by clever and unscrupulous foes. Thus it is left to some unfortunate to define in each case terms so abstract as the “public interest,” and, with very imperfect data, to discover motives and intentions. Really the Bill which has just passed through Parliament, and the Proclamation issued last week, which must be read together with it, leave us very much in the dark, for there clearly are cases for which these measures make no provision. It is important to note that the expression “enemy,” as used in the Proclamation, “ means any person or body of persons of whatever nationality resident or carrying on business in the enemy country, but does not include persons of enemy nationality who are neither resident nor carrying on business in the enemy country. In the case of incorporated bodies, enemy character attaches only to those incorporated in an enemy country.” A British subject, in brief, may not make any payment in coin or kind to an enemy as defined either directly or indirectly, nor enter into any contract with him or for his benefit. Such an injunction should be unnecessary to patriotic subjects of the Crown, but the difficulty is that it takes two to make a bargain, and the bona fides of one party only can be tested. Thus it is provided that “ where an enemy has a branch locally situated in British, allied or neutral territory, not being neutral territory in Europe, transactions by or with such branch shall not be treated as transactions by or with an enemy.” As we pointed out in our last issue, this proviso leaves a wide loophole for evasion—not by British consignors but by fraudulent consignees. It enables German coaling stations to convert cargoes of Welsh coal to the benefit of the enemy’s navy, and there is no safeguard that is of any real value, if we except the vigilance of our Navy. When we come to businesses in this country, the difficulty becomes still more intense. When the Bill was again considered in the House of Commons this week, Mr. Samuel Roberts asked that there should be a regular process not only for enemy concerns with branches or agencies in this country, but also for companies carrying on business in this country for the express purpose of undermining British trade. Indefinite and impracticable though it may be, this is a very rational request. The organisations run by Mr. Hugo Stinnes provide a case in point. Some of these, such as the Mersey and Clyde Coaling Company Limited, and the Northern JUnion Mining Company Limited, not only have English titles and habitations, but boards of directors which give little clue to their real nature ; yet we have no doubt that contracts made with either would accrue to the personal advantage of Mr. Hugo Stinnes, to that of the Rhenish-Westphalian Kohlenkontor, of which he forms no insignificant component, and to that of the Prussian Government, who have always regarded his vast enterprises as benign. The amendment introduced by Sir John Simon, which provides that the Board of Trade may examine the books of a company where “ one-third or more of the issued share capital or of the directorate of the company immediately before or at any time since the commencement of the present war was held by, or on behalf of persons who were subjects of, or resident or carrying on business in, a State for the time being at war with his Majesty” provides for cases where shares have been nominally transferred to, say, naturalised British subjects, and to some extent it covers the ground, although, curiously enough, it seems to deal also with British firms who may have been so unfortunate as to have been running business establishments in Germany prior to the war. But there are other reconstructed concerns, which deserve similar attention; we are not greatly impressed by the protestations of some of these recognised agencies, for the “ British ” management and capital now enlisted may obviously be the result of subterranean negotiation, and a specious means of keeping an enemy business intact. And when the Board of Trade has examined the books of a doubtful concern, it is not clear that it can take any really effectual action to prevent goods or money, after many vicissitudes, frotn reaching the enemy. Into the other provisions of the Bill we shall not enter here, but we venture to say that it will fail in many instances to serve the principle by which it is dictated. It is contrary to all common sense, of course, to wage unreasoning and indis- criminate war against all industry that has sprung from German sources, so far as to throw British labour on the streets and destroy British capital, or to endanger the existence of our own industries in the satisfaction of an ultra-patriotic ideal. But our enemies do not live only in the Fatherland, and it is probable that we shall continue to give our protection and patronage to inimical interests, on the sole condition that no money for the present is transmitted to Germany or Austria; we may still allow German agencies, to engage in the distribu- tion of British goods, and enable German capital concerns, by maintaining “ so-called ” works— where the manufacture consists only in the assembling of parts—to keep going until the end of the war, when the custom will again be handed over to the real sponsors. Even the interests of British labour and capital must be sacrificed at times where these conflict with the safety of the nation. Some satisfaction, however, may be derived from the fact that, although it may be difficult for the Board of Trade to arrive at the true facts of the case without recourse to “ biassed and jealous competitors,” on the other hand the risks attendant upon subterfuge and the penalties for infringement may make it difficult for our enemies to obtain the human tools necessary to carry on this vicarious work. If there should exist any doubt Rescue respecting the utility of the enquiry Apparatus, by the Doncaster Coal Owners’ Com- mittee upon the efficiency of self- contained rescue apparatus it should be dispelled by an unprejudiced study of Dr. J. S. Haldane’s Second Report, describing the efforts of manufac- turers to remedy the defects which had already been discovered in the first series of tests. It will be remembered that the First Report was not altogether encouraging, every one of the appliances having exhibited more or less grave defects, some of which were positive sources of danger to the wearer. This report came at an opportune moment when the Home Office were contemplating the compulsory use of self-contained breathing apparatus at every colliery; and it cannot be doubted that the straightforward manner in which Dr. Haldane showed up the weak points of these appliances as then available was largely responsible for the more reasonable attitude since shown towards the smoke helmet. But it has done more than this. It has served to emphasise vital defects, thus enabling manufacturers to concen- trate their attention upon their eradication, and on the whole with quite gratifying results ; for the tone of Dr. Haldane’s report is far more encouraging with regard to several forms of breathing appliance in which, one way or another, development appears to be proceeding upon sound lines. A useful and highly interesting feature of this report is the investigation carried on at Doncaster upon the behaviour of the apparatus in hot air. This involved special arrangements calculated to reproduce as far as possible conditions likely to be encountered in dealing with underground fires. The physiological effects of hot air had already been demonstrated by Dr. Haldane, who had shown that it is the wet-bulb temperature which is important in this connection. Neither the temperature of the air, its moisture content, nor its relative humidity matter much so long as the wet-bulb temperature is sufficiently low. In these earlier investigations, however, none of the wet-bulb temperatures exceeded the body tempera- ture, and it was therefore necessary to examine the effect of still higher wet-bulb readings. The results entirely confirmed Dr. Haldane’s previous conclu- sions. Under these conditions there was a rapid rise in the body temperature leading, even after a few minutes of exertion, to a dangerous subjective condition which could be produced either by the rise in body temperature or by the air furnished by the apparatus becoming too hot to breathe. The latter condition was particularly experienced in some cases, owing to the heating of the caustic-soda purifier. For these reasons it was found that a wet-bulb temperature higher than 80 degs. Fahr, rapidly curtailed the working power of a man wearing the rescue apparatus. Great importance thus attaches to methods for keeping the purifier cool, and this result already promises to be successfully attained in various ways. It might perhaps be thought that this particular difficulty would be entirely overcome by the use of liquid air in the place of oxygen cylinders, but Dr. Haldane found that very little advantage was derived from the coolness of the air in this class of apparatus, although the improved liquid-air apparatus lately installed in Durham hnd Northumberland is far more satisfactory than previous types of this class, and is stated by Dr. Haldane to be the first really successful application of the liquid - air principle to mining conditions. The practical difficulties involved in the use of liquid air, however, still render this class of apparatus, in the opinion of Dr. Haldane, inferior to oxygen cylinders both in convenience and in adaptability to mining conditions. We cannot for obvious reasons follow Dr. Haldane through all the merits and demerits of the machines tested by him. As stated above, the results in certain cases seem to be highly promising, and manufacturers are deeply indebted to these Doncaster investigations for valuable guidance in the further perfection of these appliances. It was quite to be expected, in a report of this nature, that some comment would be forthcoming upon the position created by recent legislation, to the embarrassment alike both of mine managers and manufacturers, by attempting to enforce regulations in advance of the progress of invention. Two equally undesirable results have been thus produced. As matters stand, any sort of breathing appliance would fulfil the requirements of the Act, and a condition has arisen which might have had serious consequences as regards the safety of rescue brigades in collieries. These two investigations have done much to mitigate the mischief which might have arisen from ignorance of latent defects the practical importance of which had not previously been recognised either by mine managers or by manufacturers. Mine managers are still confronted with a difficult problem in the selection of rescue apparatus. In the case of the Doncaster rescue station, Dr. Haldane has practically reduced the choice to two only of the
