The Unheated Greenhouse. By K. L. Davidson. (G. Newnes Ss.

6d. net.)—There is, of course, much to be said for the " unheated " glasshouse. Fires are costly and precarious. Your gardener oversleeps himself or takes a drop too much ; a sharp frost coincides ; and the care of months is lost. Every one must judge for himself. If profit is to be made of things grown, heat must be used so as to get them ready for the early market. If, however, this consideration is set aside, and it is desirable to do sway with cost and risk, here is an admirable guide.—Another set of special circumstances is provided for in Seaside Plant- ing for Trees and Shrubs, by Alfred Gant (same publishers, Is. net).
