The " StahV consumed 50 bushels of apples. 



producing 323^ pounds dried fruit 

 yielding 6^ pounds per bushel, 

 costing 5 cents per pound. 



The amount of fruit evaporated in a day was far below the 

 guarantee of the manufacturers. This may have been partly due 

 to lack of skill of the manipulators ; but we think the results 

 obtained are much nearer what would be secured by the 

 average operator than what are claimed by the manufacturers. 

 The latter assert a capacity of from eight to twelve bushels per 

 day of fifteen hours ; but the results of our experiments place 

 their capacity at only four to five bushels per day of ten hours. 

 The capacity of the paring and slicing apparatus was far greater 

 than that of the combined evaporators ; and it was found that one 

 man could pare, core and process the fruit after one evaporator 

 was filled as fast as the evaporators combined could care for it. 

 This leads us to the conclusion that for projit an evaporator oj 

 much greater capacity must be used; and that the small evaporators 

 can he oj little value except when the operator is engaged in other 

 work, where the short time necessary to fill it and care Jor the fire 

 would not interjere loith that work, — as, for instance, where 

 women or children are occupied near the evaporator. 



Co-operative evaporators of large capacity are built in mauj 

 places, where large quantities of fruit are put in at once and 

 allowed longer time to cure without the danger of burning, and 

 where sufficient fruit can be worked up to keep pace with the 

 ripening of all varieties. This would seem the most promising 

 method of utilizing this large product which now goes to waste. 



The quality of the evaporated apples depends upon three things; 

 namely, the quality of the fruity its state of ripeness and the variety 

 used. As to the first, it may readily be seen that the larger, fairer 

 and smoother the fruit, the better the quality of the product. In 

 the second case, the results of our experiments show that sound, 

 fresh fruit gives a larger and better product than over-ripe fruit, 

 the yield under these conditions ranging from four to seven pounds 

 per bushel. The quantity and quality of the product also de- 

 pend upon the variety. The varieties used in the test were as 

 follows, arranged in groups according to the quality of the 

 product : — 



Producing the best are the Siuaar, S710W, Ben Davis, Ilurlburt, 

 Baldwin and Willow Twig. 



Producing the next best quality are the Westfield Seek-no-further, 

 Rhode Island Greening and Red Russet.
