246 THE POME FRUITS 



because they will not keep and only aid in destroying the 

 value of the pack. 



As soon as the apples are packed, they should be precooled 

 and stored in a cold-storage plant. For home use a cool 

 cellar is often satisfactory. - However, in any event the 

 apples must not be exposed to heat and sun, because this 

 causes them to ripen up quickly and deteriorate in a short 

 time. 



Varieties. — There are a great number of varieties of apples. 

 Each region is adapted to the growing of certain well-defined 

 groups of apples. The varieties that are found to be the 

 most profitable by experienced growers are usually the 

 popular sorts in the various districts. There is no way of 

 knowing exactly what variety will do the best in any one 

 locality, and therefore the variety should be selected accord- 

 ing to the experience of some progressive grower in each region. 



The selection of varieties will depend upon whether they 

 are for home or for commercial use. If they are wanted for 

 the home a larger number of varieties can be selected, cover- 

 ing a longer ripening period. If the varieties are for com- 

 mercial planting, it is always advisable to select only four or 

 five good standard sorts. The selection of only a few varie- 

 ties for commercial planting is necessary, because the grower 

 wants to have his crop ripen up at the same time and also to 

 have a sufficient quantity of one kind to be profitable. All 

 buyers of fruit demand a quantity of a few varieties and 

 consequently they will not buy a few bushels of a number of 

 varieties. 



Some varieties are very cosmopolitan and can be adjusted 

 to many different regions, while other varieties are adapted 

 only to limited areas and they cannot be grown out of these 

 well-defined places. The Ben Davis, Baldwin, Duchess of 

 Oldenburg and several others can be grown over a great area, 

 while the Yellow Newton and some other varieties can only 

 be grown in certain regions. 



Some of the most profitable varieties are the Baldwin, 

 Ben Davis, Gano, Winesap, Greening, Grimes, Jonathan, 

 Missouri Pippin, Spy, Duchess of Oldenburg, Tolman Sweet, 

 Wealthy and a few others.
