In a somewhat later experimental study, Dr. D. W. Griffith 

 of the U. S. Department of Agriculture, carried on extensive 

 culture of various species of possible forage cacti in Mexico. 

 In general, his findings were in agreement with those of Pro- 

 fessor Thornber, but the best species for Texas were still dif- 

 ferent from those found desirable in Arizona, the best spineless 

 type being a variety developed in Italy where it is grown for 

 fruit. 



Finally, will it not be agreed, that while it is unpleasant to 

 have rocks thrown at one's pet idols, or doubts cast at one's 

 favorite fairy stories and myths, there are still plenty left, 

 and there is also satisfaction, though of a different . kind, in 

 feeling the advent of a little more maturity?
