Here was a direct saving of £237 to £240 10s.--$1,185 to $1,202.50--per ton. Altogether the purchase of glycerine recovered from military organic waste represented a saving of £312,650--$1,563,250--because the nation obtained for £77,350--$386,750--what otherwise would have cost £390,000--$1,950,000. This figure is not quite complete because, inspired by the success achieved from the milling of the swill at home, the army in France established similar stations behind the lines upon the other side of the Channel. When these were brought into operation the shipment of fat and grease recovered from the organic waste of the British Expeditionary Force in France represented 5,000 tons a year, whence 500 tons of glycerine were derived. The 5,000 tons of fat won from the swill-tubs of the army in France realized £140,000--$700,000--while the total saving recorded under the heading of glycerine secured from army waste fat was augmented to £432,000--$2,160,000. During the year in question the aggregate financial economies directly secured from the exploitation of organic army waste, in conjunction with the introduction of ways and means to reduce the yield of such residue from the observance of improved culinary methods and reduced consumption of foodstuffs was approximately £5,626,000--$28,130,000. Finally, to demonstrate the value of this contribution to the aggressive resources of this country, it may be stated that the 1,800 tons of glycerine derived from the 18,000 tons of tallow recovered from the army swill-tubs, rendered it possible to turn out sufficient nitro-glycerine to serve as the propellant charges for 18,000,000 eighteen-pounder shells. The success accomplished with the army waste fat and grease prompts the obvious inquiry as to why comparative methods cannot be adopted in civilian circles. The average household has but little conception of the value of its fat losses. It should not be an impossible task to segregate the waste from the house at the source, and to submit it to similar treatment. The majority of our civic and municipal authorities possess buildings which could readily be adapted to the installation of the necessary plant, and the capital outlay therefore need not be heavy. The disposal of the various by-products would not be attended by any difficulty. True, under war conditions abnormal prices ruled, but even to-day they are attractive and are likely to continue to remain so for an appreciable time to come.
