siderable success in stabilizing labour conditions, and brought to an end the period of unrest.

Almost immediately the Act was passed a strike occurred in the South Wales mines, and it required a personal visit of the Minister to persuade the men to return. But this was the last serious outbreak for a very considerable period.

In regard to female labour and the abandonment of union rules, the objections of the ordinary trade unionist to permit- ting unskilled labour to do work previously regarded as skilled had been steadily weakening as the shortage of labour became more acute, and as experience of making shells and fuzes on repe- tition methods spread through the country it became more ob- vious that the work was unskilled. Finally the disinclination to surrender pre-war practices had largely arisen from the fact that it was impossible to prevent the changes spreading to private work, and in any case it was extremely difficult to distin- guish between Government and private work; but as the year proceeded private work fell more and more into the back- ground. Prejudice on the part both of employers and work- people against the employment of women in engineering work had still to be overcome. The men's opposition to the women was considerably appeased by the decision that women doing skilled or semi-skilled work should be paid the same rate as the men displaced, while the fixing of a minimum wage for un- skilled female labour of r a week tended to raise the level of women's wages in general and minimize the possibility of men's wages being prejudiced. A department was started to encourage welfare work in the factories, and in many congested districts housing and hostel schemes were initiated. From the passing of the Act the employment of women on munition work increased continuously until the end of the war. In the succeeding six months, the " badging " system of the Minis- try (see LABOUR SUPPLY AND REGULATION) caused a decided check to recruiting from the engineering factories. Indeed, at a later stage it appeared that badges had been given rather too freely, and many badged men were ultimately released for service. The plan of mobilizing a corps of war munition volunteers met with only a qualified success at this period, and a great difficulty was experienced in obtaining the release of men from the army. This problem was somewhat simpli- fied after the introduction of compulsory military service.

The " Munitions Levy " was ultimately succeeded by the general Excess Profits Duty, leviable on all firms in the country, and the assessment passed from the Ministry into the hands of the Board of Inland Revenue. This Act, which created the powers exercised by the labour section of the Ministry of Mu- nitions, involved a very extensive interference by Government with the liberty of the individual worker, and was the more remarkable since at this date the army was still dependent upon voluntary enlistment. Its passage was only made possible by the clauses limiting private profit on munition work.

The Production Programme. Early steps were taken to ascertain the general requirements of the War Office. But the Minister, in view of the circumstances of his appointment, considered himself in no way bound by these demands, and held that he was free to place such orders as would ensure an enormous increase in the munition-making capacity of the country and also to look very far ahead in placing orders abroad.

Guns. The most notable action of Mr. Lloyd George in this respect was in the matter of heavy artillery. In June 1915 a con- ference on munitions was held at Boulogne, at which French ex- perts strongly urged the necessity of increasing enormously the proportion of heavy artillery per division. Field artillery had practically no effect on deep trenches, and as the whole front had become a vast entrenchment it was necessary to contemplate having in the field as many heavy guns as field guns. Following upon this conference, Sir John French put forward a demand to the War Office to provide for each division and army corps a definite establishment of heavy guns and howitzers 6 in. and upwards. This standard was worked out on the basis of 50 divisions and put forward as a definite demand. In view, however, of responsibilities in other theatres of war and of pressure from the French Government, the War Office was already laying its plans on the basis of 70 divisions. The gun programme, therefore, before being passed to the Ministry was proportionately increased and an allowance added as reserve. On

receipt of this demand the Minister early in July allocated these orders among the armament firms and authorized the necessary ex- tensions to plant and the purchase of the large quantity of machine tools required from English and American manufacturers. It was obvious, however, that the scale of the plant to be developed would determine the date at which these enormous orders could be fulfilled. Mr. Lloyd George had at this time urged the necessity of increasing the British military effort to 100 divisions. -Partly with this object in view and partly to broaden the basis of the munition output of Great Britain, which was still far behind that of Germany, he increased the programme on his own responsibility in Aug. 1915 to a loo-division standard, and ordered all the con- sequential demands for shell, fuzes, explosives, propellants, steel, etc., to be calculated on this basis. This action was much criticized both on the ground of expense and the alleged impossibility of train- ing personnel to man so vast an armament. But Mr. Lloyd George was supported by the Cabinet, though arrangements were in train in the spring of 1916 for handing over the surplus to the Allies and particularly to Russia if and when it matured.

Within a few days, however, of the opening of the battle of the Somme in July 1916, G.H.Q. revised their ideas and put forward an entirely new basis of equipment. The establishment of 6-in. howit- zers, which had seemed large in July 1915, was trebled ; the demand for 8-in. and o-2-in. howitzers was doubled, while a new item was added in the shape of heavy long-range guns. When the programme was examined it was found that the surplus orders of the Min- istry covered these increased demands for all heavy howitzers ex- cept the 6-in. and that only comparatively small additions to the existing gunmaking capacity would be required to enable the Ministry to cope with the whole of the new programme. So complete a vindication of Mr. Lloyd George's courageous action, with its far- reaching consequences in the subsequent campaigns, marks it as one of his great contributions to the Allied cause. Indeed, his contention that gunmaking capacity would be one of the vital factors in the campaign was repeatedly confirmed by subsequent events which involved new calls upon British gunmaking capacity. In the first place French experience at Verdun, and subsequently British experience on the Somme, soon showed not only that wastage by destruction would be far larger than had been anticipated, but also that expenditure of ammunition was on so huge a scale that the number of guns worn out and needing relining would be very large indeed. Secondly, it was decided before Christmas to arm all merchant ships with two guns capable of coping with submarines. Thirdly, an urgent and increasing demand arose for anti-aircraft guns, not only on the front but also for the defence of London and many other strategic points in Great Britain. Finally, the deyelop- ment of the use of tanks on a large scale called for the production of an enormous number of guns of small calibre.

Hence it was not until the middle of 1918 that the output of guns of all kinds became sufficient for these combined requirements, and after the output and importation from America of large-calibre shells had enabled heavy stocks to be accumulated, it became nec- essary to divert some of the projectile factories from shell-making to the repair of guns.

Ammunition. The highly technical processes involved in gun manufacture remained for the most part in the hands of a com- paratively few firms. The ammunition programme, on the other hand, with its immense drain on materials and plant, until the end of the war absorbed more than half of the energies of the Ministry and of the munition factories, and was the main cause for the control which was ultimately imposed upon the industry of the country. The shell itself, which at first figured so largely in public discussion, is, as its name implies, merely a container of H.E. or of bullets, and the problem of finding sufficient explosive, propellant, fuzes, primers, cartridge cases and the score or so of other components which go to make up a round of ammunition, proved much more difficult than the manufacture of the shell. The balancing of output, including the appropriate provision of the various metals or chemical sub- stances, was not accomplished without much experience; and as from time to time particular items were ahead or in arrears, the Ministry had to provide for the accommodation of large stocks at all stages of production. The programme thus involved the building-up of a colossal stores organization, the burden upon which was greatly increased by the irregularity in the rate of consumption on the front. Moreover, as the Ministry found it necessary to make itself directly responsible for supplying materials to contractors it became not merely a purchasing department but one of the greatest selling organizations in the world.

The ammunition programme was calculated from the enlarged artillery programme on the basis of the expenditure per gun per day asked for by G.H.Q. But as it was impossible accurately to foresee to what extent new firms or new shell factories would produce the output expected from them, there was added to the net shell demand a margin of 50% in the case of light shell (up to 4-5 in.), which had been ordered largely from inexperienced firms, and 33 % in the case of heavier natures, which at first were confined to more experienced firms or new factories built for the purpose. Orders for the former were placed to a large extent through the local committees called into existence by the War Office Armaments Committee or by the Ministry during the June publicity campaign. In some cases the
