THE CANNING OF PEAS. 



BY-PRODUCTS. 



The pea vines are a waste or by-product at many factories. Some 

 pay to have them taken away, some pile them up to rot for fertilizers, 

 some dump them upon the land, others make them into silage, and 

 still others convert them into hay. In general the value of the pea 

 vine for food is only slightly appreciated. The silage can be made 

 cither in the silo or by piling in a large stack and rolling well. The 

 latter method is economical, as the expense of a special building is 

 obviated and, if well done, the losses upon the sides and top are not 

 great. Analyses made by W. J. Jones, jr., Indiana state chemist, 

 on stacked pea-vine and sweet-corn silage gave the following results :

These samples were taken in May from stack silage which had 

 been put up the previous year. A comparison of the analysis of the 

 pea-vine silage with that of the sweet corn shows the former to be 

 much the richer in protein. A comparison with regular corn silage 

 is also favorable to the pea silage. If $2.50 a ton is accepted as 

 the value of regular corn silage, the pea-vine product should be worth 

 more. A sample of good pea-vine hay was also analyzed and gave a 

 value between that of clover and timothy. Stock relish both the 

 silage and the hay.

These analyses indicate that the by-product has a food value too 

 great to be ignored, and that an effort should be made to transport 

 the vines to the factory in good condition in order to get the best re- 

 sults from them.
