SEED AND SEED SELECTION 4I

 those of alfalfa, and have a very pronounced groove be- 

 tween the main body of the seed and the ridge which 

 marks the location of the rootlet of the young plant with-

A COM3ION WSED IN IMPORTED ALFALFA SEED

 should be rejected. (See illus. opp. p. 13.) 



"The farmer is often to blame for the poor seed of 

 which he makes complaint. Prime alfalfa seed is expen- 

 sive, and a cheap grade will inevitably be poor in quality, 

 containing much dead seed, rubbish, and the seeds of 

 many kinds of weeds. Where 'cheap' alfalfa seed is 

 demanded it will always be sold, and buyers need not be 

 surprised by its quality. On the other hand, there is no 

 excuse or palliation for the offense of selling, under the 

 name and at the price of standard alfalfa seed, seed of 

 substituted species. It is the duty of seed dealers to ascer- 

 tain beforehand the character and genuineness of seed 

 that they sell vmder any given name, and this applies to 

 the retailers as well as to the wholesale dealers. On the
