THE BENEFITS FROM SILOING CROPS. 265 



directly from the fields. The season, therefore, 

 for providing soiling food directly in areas as far 

 northward as in Canada, does not cover a larger 

 period than three to four months, other things being 

 equal, therefore, the further northward the location 

 the greater will be the necessity for siloing the food. 



Some crops are much more difficult than others 

 to cure in the dry form. Such are corn, sorghum, 

 the non-saccharine sorghums, the cow pea and the 

 soy bean. The necessity for silos therefore is 

 usually greater when these are staple crops than 

 when they are not. The non-saccharine sorghums 

 however have greater adaptation for dry conditions, 

 as shown in Chapter IV, Part i., hence it is not so 

 necessary to make these into silage, since the weather 

 is favorable to curing them in the dried form. 



Some sections of the country are almost exclu- 

 sively devoted to the production of dairy products. 

 Other sections produce virtually none of these. The 

 close relation between succulent foods and successful 

 dairying is generally recognized. It follows there- 

 fore, other things being equal, that the necessity for 

 the silo will grow with the growth of dairying. 



Silos Not Always a Necessity. From what has 

 been said in the preceding paragraphs it will be 

 evident that silos are not nearly so much of a neces- 

 sity in some places as in others, and it would not be 

 going too far perhaps to say that in certain areas 

 they are not a necessity to any extent. It is evident 

 that in the moist New England states which produce 

 corn in good form for the silo, the necessity for silos 

 will be greater than in the moist climate on the Pacific 

 coast in areas too cool for the successful growth of
