The great secret in Tulip propagation is now open to the world, though not popularly understood. Propagation is effected by offsets, from the fact that varieties will not reproduce themselves from seed. The seed produces only 'selfs ' or Mother Tulips, which only break into variegated forms at long and uncertain peri- ods. Consequently the flowers must be cut away as 2595. Round-petaled Tulips in a five-inch pot (XK). soon as they appear; if not, nearly the whole of the plant's energies would go to the development of the seed, —nature's method of reproduction, —and the bulbs produced would be small and with but few or no offsets. From nature's standpoint the bulb is of consequence as a means of reproduction or perpetuation of the species only in case of failure of seed production. By cutting the flower-stems as soon as the flowers are sufficiently developed to show, there is no mistake as to variety, and the plant's energies are wholly directed to reproduction by offsets which, from large bulbs, are freely produced. There is a great difference in varieties in this respect. The increase is not far from tenfold an- nually; that is, the parent bulb will produce that num- ber of offsets, which must be grown at least three years before they can be sold as first class. By the cutting of the flower-stems the plant's period of development is materially shortened. The bulbs will mature at least four weeks earlier tha
