NEW CREATIONS IN PLANT LIFE 



remain a week or more, after which they will 

 readily form roots and start to grow anywhere, 

 even on a board, a pile of rocks or the roof of 

 your house if you choose. When wilted, the 

 usual way is to plant so that about one-third 

 of the cutting is below the soil. They may be 

 planted in an upright position or at any angle 

 from the perpendicular ; it makes no difference 

 to the opuntias. On fairly good soil in general 

 field culture for stock feed, the giant-growing 

 kinds should be planted about three feet apart 

 in the rows and the rows should be about 

 eight feet apart. In orchard planting for the 

 large-growing, fruiting varieties, probably four 

 by ten or twelve feet would be better." 



So the new cactus goes to the world after 

 many years of exacting study, exhaustive ex- 

 perimenting and searching tests. From the 

 commercial standpoint, from the standpoint of 

 those who live and die where Famine stalks, 

 as well as from the point of view of those who, 

 from economic reasons, would see the vast 

 waste places of the earth made fertile, this is 

 certainly the most commanding act in the 

 life of the world's greatest constructive plant- 

 breeder, an act of splendid usefulness.
