INTRODUCTION. 



The rapid development of the fruit-packing industry in the United 

 States within recent years has had a tendency to direct the attention 

 of packers to the large accumulations of by-products which at pres- 

 ent are valueless because of their lack of utilization. The nature of 

 these waste products differs, according to the fruit from which they 

 result. In most cases some portion of the fruit is discarded because 

 it has no further use. Often it is the exterior portion, but in many 

 cases, especially with fruits which require pitting, the waste prod- 

 ucts consist of pits or seeds which must be removed before canning. 



In previous publications of the Department of Agriculture * atten- 

 tion has been called to the enormous quantities of raisin seeds and 

 peach and apricot pits which may be made to yield valuable com- 

 mercial products, and already some manufacturers are turning their 

 attention to these waste products with a view to their profitable 

 utilization. 



More recently the attention of the writer has been called by fruit 

 packers to the waste which results from the cherry-packing industry 

 of the North Atlantic, North-Central, and Western States. This is
