HORTICULTURAL JOTTINGS.

Some idea of the importance and extent of the jam industry in England may be gathered from the fact that one firm alone—that of Mr. W. P. Hartley, of Liverpool turns out, during the busy part of the summer months, at the rate of a hundred tons a day. This is equal to 12,000 21b jars daily, which in volves the employment of about 1.100 persons. There are, of course, many other jam factories, both in England and Scotland. D. Imperials (the tree dahlia), when growing in perfection, is a truly grand plant, stately and beautiful; but a good specimen of it is rarely seen. The following may, however, be of use to those who desire to see it in perfection. The roots may be either lifted in autumn and wintered in the usual way of the common dahlia, or they may be lifted at the present time, potted, and placed in heat; or the roots may be divided if deemed advisable. After the buds have started and the shoots are about three inches long, they may all be taken off except one, and grafted on tubers of the same, or if dwarfer plants are desired, on tubers of the common dahlia, and placed in a propagating frame. As the tree dahlia requires a long season the plants should be grown as stiong as possible, then when the weather has become fine they may be planted in very rich soil in the flower garden, where those on their own roots aym attain a height of 10ft or 18ft.
