Many branches of the service you are equipping with instruments of very high expense indeed. A field gun does not cost less, I believe, than £600. And to every thousand men you actually put into the field you may reckon at least four of these instruments. Every time one of them fires a shot it fires away fifteen shillings. Apart from the wear and tear of the field piece itself, a modern quick-firing piece, firing moderately, will get rid of a ten pound note in ammunition in a minute, and each piece is allowed from the base onwards 1000 rounds.
Further, an army is equipped with heavy artillery, the pieces of which cost anything from many hundreds to many thousands of pounds, according to their calibre (a 9.2, with its mounting, comes to near £12,000); and it is also equipped with a mass of auxiliary material--vehicles, mechanical and other, telephones, field kitchens, aircraft, and the rest--none of which expense attaches to the same body of men in their civilian life.
The scale of the business is further emphasised by the fact that once war is engaged the nation as a whole is suddenly called upon to produce material not only _more expensive_ upon the average, man for man, than the same men would have used and consumed in the same time in civilian life, but things _different from_ those things which the nation was organized to produce for use and consumption during peace. That change in effect is costly. And yet another element of cost is the novel use of existing instruments.

Every time one of them fires a shot it fires away fifteen shillings. A modern quick-firing piece, firing moderately, will get rid of a ten pound note in ammunition in a minute. Each piece is allowed from the base onwards 1000 rounds and the extent of this quantity is illustrated in the diagram--40 rows of shells, 25 in a row.]
It is more expensive to use an instrument for some purpose for which it was never designed, than to use it for some purpose for which it was designed. That is a universal truth from the hammering in of a nail with a boot heel to the commandeering of a liner for the transport of troops. And in time of war the whole nation begins at once to use instruments right and left for military purposes, which instruments had been originally designed for civilian purposes.
