Our correspondent has our thanks for his good advice; at the same time, we think that in the "Hints to Amateurs" we meet many of the requirements of the class of gardeners he refers to, and in our papers on Flower-Gardening last year, and those on the Kitchen-Garden in this, we meet many more of them. Success in horticulture, as in all other matters, depends so much on attention, industry, and perseverance, that we fear no directions, however simple and plain, would make a man who lacked these qualities a successful cultivator of either flowers, fruit, or vegetables.

It will be our endeavour in the future, as in the past, to make this magazine a safe guide for tyros in horticulture; but we do not write for them alone, and we must not fill our pages with that which is purely elementary.

Z. - For the colours you name there are no better plants than those in your list. For blue, use Lobelia speciosa. Sow the seed at once in heat, and bring it on in heat for a time, pricking it out in pans or boxes as it progresses till May when it should be hardened in a cold frame, and planted in the border about the 20th of May. See that you get the true Lobelia speciosa, as Gracilis is sometimes sold for it, and it is worthless. Cut back the Briar to the lateral; the bud is on as soon as you see that the latter has got hold; and dust it well with powdered hellebore when the wood is damp: this will prevent the attack of the caterpillar you refer to.
