middle of November, but no flowers had appeared. The vines were 

 two to three feet long and they covered the ground completely, and 

 made an excellent mulch. Peas sown September 20 reached a height 

 of about six inches and were not large enough to afford a satisfactory 

 cover ; yet, if sown very thick, peas could be put in at this time with 

 fair result, in cases where the ground could not be used earlier. 



Aside from these covers, various kinds of clovers were sown in mid- 

 season for purposes of comparison, but they made a poor stand and 

 afforded very little protection to the soil. Rye sown late in Auguht or 

 early September made a fair cover, but it is no better than common 

 field peas, if as good, and its fertilizing value is small. 



The following analyses show the fertilizer values of the various 

 plants here discussed. The vetches and peas were analyzed at this 

 Station. The analysis of cow peas is taken from Professor Teller's 

 recent studies in Arkansas,* and that of clover is compiled from reli- 

 able sources for comparison.
