Cactus Fruit Approaching Spinelessness

The one prominent defect of the cactus fruit is that it retains a certain number of spines or spicules, even when the slab upon which it grows has become entirely smooth. Mr. Burbank's experiments are now directed towards the production of a perfectly spineless fruit, and those experiments are approaching completion. The variety of fruit here shown is almost smooth, retaining only traces of the offensive spicules. It is believed that other varieties, almost at fruiting age, will bear pears that are altogether spineless.
