MAMMOTH CLOVER i:23 



and in the loam and light loam soils of the Puget 

 Sound country. It has greater power than the com- 

 mon red variety to grow in stiff clays, in sandy soils 

 underlaid with clay, and in areas where moisture is 

 insufficient near the surface soil. In stiff clays the 

 roots penetrate to a greater distance than those of 

 the medium red variety and gather more food. Con- 

 sequently, a stiff clay soil that would only furnish 

 a light crop of the medium red variety in a dry sea- 

 son may furnish an excellent crop of the mammoth. 

 The quality of the hay is likely to be superior to 

 that grown on soils altogether congenial, since it is 

 not likely to be over-rank or coarse. 



On sandy soils underlaid with clay, and especially 

 where the clay is some distance from the surface, 

 this clover is more certain to make a stand, since 

 the vigor of the plants enables them to gather food 

 until the roots go down into the clay. 



In areas where the moisture is more or less defi- 

 cient, the other conditions being favorable, this clo- 

 ver can send its roots down into the subsoil, where 

 moisture is more abundant than on the surface. Be- 

 cause of this power, it is better adapted than the 

 medium red to much of the area of Southwestern 

 Minnesota, Western Iowa, Western Kansas and 

 Nebraska, and, in fact, much of the area bordering 

 on the semi-arid country. 



On clay soils that are so saturated with water that 

 in the winter or spring the clover is much liable to 

 heave, there is conflict in opinion as to whether the 

 mammoth or the common red variety will heave the 

 more readily, but the preponderance of the evidence
