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 1 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
