Everyman's Book of the Greenhouse (Unheated). By Walter Irving. (Hodder

and Stoughton. 5s. net.)—By " unheated" is meant not kept up to forcing temperature; the use of an oil or gas stove is recommended, as it largely increases the utility pf the house. (The writer of this notice would recommend the gms where it is available ; some plants, MaMchal Niel Rose, for instance, he has ]mown killed by oil-fumes, so difficult to prevent.) A most useful volume this.
