A Remarkable Fruit Colony
Here are forty-three fruits on a single slab of a spineless cactus. It is hardly necessary to state that this is one of Mr. Burbank's highly developed fruiting varieties. The slabs do not often quite duplicate this record, to be sure; but on occasion they even exceed it. A hundred tons to the acre is the possible yield of fruit like this.
