Data on one fourth bushel of apples, small, pared, and quartered.

(3) One busliel of apples will make from 6 to 7 pounds evaporated 

 apples. The average is about 6 pounds to the bushel. 



(o) Green api^les weigh from 56 to 60 pounds, and the evaporated 

 profluct about 6 pounds when done. The loss in actual weight would 

 bo about 50 pounds. They would weigh, after being peeled, sliced, 

 and cored, about 35 pounds to the bushel, losing in the evaporation 

 about 29 to 30 pounds; this is all water. By this process we save 

 the saccharine qualities of the fruit. 



(4) The time required to evaporate the different kinds of apples 

 varies. In the following table each variety of apples was kept sepa- 

 rate, and the result is as near an average as can be obtained on a 

 large quantity evaporated. The difference in weight of any one 

 variety is owing largely to the difference in the state of maturity. 

 We also give the average time required to evaporate.

It will bo seen from the above extracts that the actual methods 

 adopted by the different companies do not differ very much, being 

 more or less modified to suit the requirements of their own machines. 



In drying the apples in the laboratory no attempt has been made 

 to bleach, as we are not making any commercial article, but wish to 

 conform as nearly as possible with the general practice in regard to 

 temperature used in drying, &c.
