Spineless Cactus Slabs Ready for Shipment
These are selected slabs of some of Mr. Burbank's new spineless varieties of cactus. Simply laid in a tray, and given protection against rough usage, they may be shipped anywhere in the world, practically without regard to the time required. They seem to germinate even better when somewhat thoroughly dry. Such plants as these, for nursery purposes, command a price as high as $5.00 each.
