nial, and is adapted for permanent pasture; the stems are larger, 

 more inclined to spread, the leaflets are narrower and often des- 

 titute of a light spot, the flowers are bright red and larger than 

 in Trifolium jyratense, and form a less compact head. 



The samples found at the Agricultural College, and in many- 

 other places, show all grades of intermediate forms. These two 

 species seem to be freely hybridized. 



At my request, my friend, A. 0. Glidden, of Paw Paw, Mich., 

 has made numerous inquiries in reference to its value in hi« por- 

 tion of the State, where it has been largely grown. 



L. B. Lawrence, of Cass County, who owns a large prairie 

 farm, has grown it for many years. He considers it less hardy 

 than the other species; it is more liable to "heave" in the 

 spring, and often grows so rank as to kill itself by the burden of 

 stalk on the surface. He thinks the roots are smaller and that 

 it feeds on the surface, and does not work in the subsoil like the 

 other species. He formerly pastured this clover till the first of 

 June, when he allowed it to flower and seed, which would often 

 come off early enough to plow for wheat. Recently he has run 

 over the field with a mower, clipping the tops about the first of 

 June, and allowing them to remain as a mulch, while the n(^\y 

 growth forms seed. 



D. Woodman, of Paw Paw, once sowed a field in equal divisions 

 of the two kinds, and the mammoth clover furnished double the 

 amount of feed for pasture, as compared with the other half of 

 the field. The season Avas a dry one. Others report that it is 

 better than the early kind for pastures in July and August. 



Tlie notion prevails that the mammoth clover does not make 

 as good hay as the other species ; it is often coarse and woody. 

 Another point should not be overlooked. They all agree that 

 the mammoth clover is much the most productive of seeds. As 

 this is the case, we may expect it will soon become more com- 

 mon than it is at present. Farmers will select the large kind to
