product of high commercial grade can be made from any sort which 

 has a firm texture and bleaches to a satisfactory degree of white- 

 ness. A variety of high dessert quality, such as the Northern Spy, 

 may be expected to make an evaporated product of correspondingly 

 high flavor. 



In sections where the Baldwin apple is grown extensively, it is 

 in demand at the commercial evaporators, as it meets the require- 

 ments in a fair degree and is available in relatively large quantities. 

 In the Hen Davis sections that variety supplies a similar demand. 



Most early varieties lack sufficient firmness of texture for the 

 best results and are undesirable on this account. On the other

hand, some comparatively early sorts, such as the Gravenstein and 

 the Summer Pearmain, are considerably prized in some sections. 

 The dessert quality of the latter is especially high. 



Similarly, the product made from other sorts possesses qualities 

 that are due more or less to varietal characteristics. For instance, 

 that from the Esopus is said to be unusually white. The Hubbard- 

 ston and varieties of the russet group also make very white stock, 

 the latter giving a relatively large amount of stock, by weight, to 

 a given quantity of fresh fruit. The Limbertwig is said to produce 

 from 1 1 to 2 pounds a bushel more of dried stock than most sorts 

 do. but it is not so white as that from some other varieties.
