MAMMOTH CLOVER SEED. 



In April, 1895, fifteen samples of mammoth clover seed, obtained from 

 various sources, were sown in adjoining rows, each row being eight rods 

 long. By the side of these were sown for comparison four rows of 

 medium clover with seed from different sources. All the seeds grew 

 well, and important differences were noted the first year in the growth 

 of the different rows. The second year, as the plants began to 

 blossom, the difference became more clearly marked. From the 

 following table and the accompanying notes it will be seen that sev- 

 eral of the varieties were not true to name and that nearly all the sam- 

 ples were more or less mixed. Also that there were distinct variations 

 in each variety, some samples being earlier, more vigorous, or otherwise 

 different from others of the same kind. Two of the samples were prac- 

 tically pure, No. 12, an early, vigorous and rather dwarf strain of medium 

 clover (purchased, however, for mammoth), and No. 16, an equally pure 

 and distinct sample of mammoth clover, somewhat later than the rest. 

 From the column marked ''seeds per gram" it does not seem that the 

 weight or size of the seed is a reliable test between the two varieties. 

 In this case the grains of medium clover generally, but not always, 

 weighed less than those of the mammoth clover.
