We are sending over to France _every week as_ much as the whole pre-war stock of land service ammunition in the country. As to _guns_, I would ask my readers to turn back to the second and third chapters in this little book, which show something of the human side and the daily detail of this great business, and then to look at this summary:-- _Every month, now_, we are turning out nearly twice as many big guns as were in existence for land service--i.e., not naval guns--when the Ministry of Munitions came into being (June, 1915). Between June, 1915, and June, 1916, the monthly output of _heavy guns_ has increased _6-fold_--and the present output will soon be doubled. For every 100 _eighteen-pounders_ turned out in the first 10 months of the war, we are now turning out 500. We are producing 18 times as many _machine-guns_. Of _rifles_--the most difficult of all war material to produce quickly in large quantities--our weekly home production is now 3 times as great as it was a year ago. We are supplying our Army overseas with rifles and machine-guns entirely from home sources. Of _small-arms ammunition_ our output is 3 times as great as a year ago. We are producing 66 times as much _high explosive_ as at the beginning of 1915; and our output of _bombs_ is 33 times as great as it was last year. At the same time, what is Great Britain doing _for her Allies_? The loss of her Northern Provinces, absorbed by the German invasion, has deprived France of three-quarters of her steel. We are now sending to France _one-third of the whole British production of shell-steel_. We are also supplying the Allies with the _constituents of high explosive_ in very large quantities, prepared by our National factories. We are sending to the Allies _millions of tons of coal and coke every month_, large quantities of machinery, and 20 per cent. of our whole production of machine tools (indispensable to shell manufacture). We are supplying Russia with millions of pairs of Army boots. And in the matter of ammunition, we have not only enormously increased the quantity produced--we have greatly improved its quality. The testimony of the French experts--themselves masters in these arts of death--as conveyed through M. Thomas, is emphatic. The new British heavy guns are "admirably made"--"most accurate"--"most efficient." Meanwhile a whole series of chemical problems with regard to high explosives have been undertaken and solved by Lord Moulton's department. If it was ever true that science was neglected by the War Office, it is certainly true no longer; and the soldiers at the front, who have to make practical use of what our scientific chemists and our explosive factories at home are producing, are entirely satisfied.
