In addition to these, plants of Nopalea, Cer- 

 cus, Pilocereus, Mammillaria, Echinopsis, and 

 Phyllocactus have been used in the tests with 

 twelve thousand seedlings and hybrid seed- 

 lings, the offspring of the hardiest, most nu- 

 tritious and most rapid -growing so-called 

 thornless varieties. 



Passing to more definite details, as to the 

 development of the opuntia, and the part it is

 of the earth, it is to be noted that the cactus 

 plant differs markedly from many other plants 

 in the facilities which it offers for breeding. 

 Por example, it must be pollenated in the 

 very middle of the day, in the hottest sun-
