Solving The Ice Problem.
 No. l. Cost of Natural Compared With Manufactured Ice.

It Is cheaper to harvest natural ice than 1t is to manufacture ice, Ice from a pond or lake may be put into storage for 30 cents a ton, more or less. according to the neighborhood. only then beginning.
 When the ice is to be sold in large cities 1t is usually harveated at a dis tance, Freight and carriage are ele- ments. There Is 0 heavy shrinkage in handling such Ice. between the storehouse and the delivery wagon. Labor between the icehouse and the delivery wa gon is a relatively small part or thD cost ShTinkage of the ice. freight, carriage, depreciation of lcenouses and other I-ant, interest on investment are far larger elements. Manufactured ice usually Is produc- ed from a plant in the heart of the district in which the product Is to be sold. IT may be stored to some ex- tent, but inc storage need not be much, and the product may be sold from day to day, almost as soon as 1t Is made. The element of shrinkags by melting Is smaller. The interest and taxes will usually be higher. Just as in the case of natural ice, the ac- tuaL cost of making the ice is the smaller portion of the whole cost Delivery to the ultimate consumer, when the ice has finally reached the delivery wagons, IS about che same for natural and manufactured ice.
 The labor charge, up to the deliv- cry wagon, Is not a very large item. Early in 1915 the labor value in a. ton of manufactured ice was perhaps 22 cents for a 200 ton plant. If labor has eince doubled, the present cost would be 44 cents.
 The cost per ton Of manufa cured ice differs somewhat with the size Of plant, and the locality where the plant is located.
 In ice and refrigeration, Dec, 1915, w T Price gave the manufacturing cost per ton for a hundred ton plant, seam. as $131.
 L. K. DoeIling. in A. s. R. E. Jour nal. Sept, 1915, gives the cost for a plant of a hundred tons daily capac- lty, at s1.4O a ton without interest, and $1-63 with interest on the invest men
 In March, 1915, Ice and Refrigera- ton. printed 8 comparison for cost of natural ice and manufactured ice fo1,
