FIELD CROPS.

for 4 years previons to 1804, when it was seeded to oats and clover. 

 The weights of clover, with some timothy grown on the southern third 

 or limed ends of the plats, are tabulated ; but on the unlimed portions 

 there was little or no timothy and very little clover, "the land being 

 .oecu])ied by weeds, consisting- chiefly of sorrel." From the tabulated 

 yields of clover "and the accompanying illustrations the almost marvel- 

 ous effect of lime upon the growth of clover upon this soil is readily 

 seen." 



The relative amounts of clover, sorrel, timothy, and miscellaneous 

 weeds on different plats was determined from small representative 

 areas. 



"Upon the unlimed portions there was 3A^ times as mucli sorrel with a full appli- 

 cation of sulphate of ammonia as with full applications of nitrate of soda and dried 

 blood." 



Many volunteer clusters of timothy grew on the limed portions, but 

 none on the unlimed sections. "The value of lime in connection with 

 timothy upon our acid soil was therefore most strikingly manifest and 

 was in full accord with the results secured with it in the experiment 

 with grasses upon limed and unlimed soil described elsewhere in this 

 report." 



The author concludes as follows : 



"The growth of clover upon the plats which had received no nitrogen in any form, 

 at least for 5 and probably for a dozen years, was nearly if not ([uite as good as upon 

 those which had received a large annual application from 1890 to 1894, inclusive, a 

 result decidedly in contrast to those secured with Indian corn and oats upon the 

 same plats. 



" The injury liable to result to a clover crop owing to the smothering of the young 

 plants by the lodging of the accompanying grain crop, the necessity for thin seeding, 

 and care not to employ too much nitrogen in such cases is pointedly illustrated. 



"Fresh applications of lime have appeared in other experiments to be unfavorable 

 to the growth of sorrel. It appears probable, however, that the chief value of lime 

 in eradicating sorrel is attributable to the fact that it brings about physical and 

 chemical soil conditions, one or the other or both of which are so highly favorable 

 to the growth of clover and many other agricultural plants that they are able to 

 occupy the land, thercbj^ preventing sorrel from gaining a foothold." 



Indian corn experiment, C. O. FLAGa and G. M. Tucker {Rhode 

 Island ma. Rpt. 1895, jyp. 312-316, figs. 5).— November 23, 1894, 25-pound 

 samples of each of 5 varieties of unshelled corn were hung in a corn- 

 crib; March 25, 1895, these samples were weighed. The results are 

 shown in the following table:
