METHOD OF CALCULATING THE INGREDIENTS. 
The calculations necessary in determining the proportions are as 
follows (consider the ingredients as they are listed) : 
Granulated sugar.—The amount of granulated sugar can not be 
determined until the sweetened condensed milk is proportioned. 
Gelatin (powder).—The amount of gelatin is the same as that cal- 
culated for the mix. ; 
Cream.—The 342 pounds of 30.5 per cent cream does not contain 
more than a small proportion of the fat required; hence the entire 
amount can be used. 
The amount of 38 per cent cream required can not be propor- 
tioned until after the condensed milk is proportioned, since the 
latter contains 8.2 per cent fat. 
Sweetened condensed milk.—The amount of sweetened condensed 
milk that can be used is limited by the amount of sugar and milk 
solids not fat it adds to the mix. The 720 pounds of sweetened con- 
densed milk will add only 302 pounds of sugar and 151 pounds of 
milk solids not fat; hence the entire amount can be used. 
Granulated sugar.—With the condensed milk proportioned, the 
amount of granulated sugar necessary can be determined by sub- 
tracting the amount added in the condensed milk from the total 
amount required, thus: 
325 — 302 =23 pounds of granulated sugar. 
Cream (38 per cent)—Now that the condensed milk is propor- 
tioned, the amount of 38 per cent cream may also be determined. 
The amount is obtained by subtracting the sum of the fat contained 
in the 342 pounds of 30.5 per cent cream and the 720 pounds of 8.2 
per cent condensed milk from the total amount sania and dividing 
the remainder by 0.38, thus: 
362.5 — (104.3 + 59.0).=199,2. 
199.2 + 0.38 =524 pounds of 38 per cent cream. 
Skim-milk powder.—From this ingredient must come the remainder 
of the milk solids not fat needed in the mix. This is determined
