Spineless Cactus Showing Two Months' Growth
This picture shows the rapidity of growth of some of Mr. Burbank's improved varieties of spineless cactus. The central slab originally planted has put forth several offshoots, and these of course have sent out numerous branches; so that now, only two months after the time of planting, the plant begins to take on the aspect of a cactus colony. Of course rapid growth was one of the important factors which Mr. Burbank had constantly in mind in making his selections.
