TABLE II. ANALYSIS OP ITALIAN RYEGRASS SEEDS. 



seed-grains, weeds are readily detected by their difference 

 in size, and as readily got rid of; in the fallow crops they 

 may be sown with the seed and germinate, and are then 

 disposed of by the hoeings the crop receives. But with 

 the ryegrass, whether sown for a single crop or for per- 

 manent purposes, they are placed under exactly the same 

 conditions as the cultivated plants; and as they are gene- 

 rally more vigorous in their habits, and more hardy in 

 their nature, a struggle for possession of the ground takes 

 place between them and the ryegrass, and the weakest 

 soon goes to the wall. Although there does not appear 

 to be that great difference between the weights of the 

 various samples of Italian ryegrass, which to a certain ex- 

 tent indicates quality, that is noticeable in the Perennial, 

 the amount of adulteration in the former is always much 

 greater than in the latter, as the greater portion of the.
