VOL. 7 of Scientific Horticulture, the journal of the Horticultural Education Association (from the Hon. Editor, Mr. B. T. Pearl, S.E. Agric. Coll., Wye, Kent. 4s. net.; 4s. 6d. by post, February 1939) contains a well-balanced collection of papers for gardeners, both practical and professional. There are papers upon commercial horticulture in Eire, Devon, Lancashire and Bedfordshire, and articles upon the practical control of slugs by the use of ‘Meta fuel’, by S. G. Jary, and the horticultural work of the Land Settlement Association, by H. Fairbank. Messrs. H. G. H. Kearns and H. Martin contribute an account of the physical properties and practical use of combined insecticidal and fungicidal washes for use upon expanded blossom and foliage. They conclude that oil emulsions afford the most promising basis for combined direct and protective sprays, and practical instructions are given for their use upon various tree fruits and soft fruits. Interesting possibilities of the controlled nutrition of horticultural crops by growth hi nutrient solutions are envisaged by Messrs. S. R. Mullard and R. H. Stoughton. Though the huge increases in yield claimed for the method in California were not realized in England, growth of gladioli was superior to that from soil-grown corms. Lela V. Barton summarizes the work of the Boyce-Thompson Institute, New York, upon germination and dormancy in seeds. Effective pre-treatments for dormant seeds and for the after-ripening of certain species, are condensed into three tables of great practical utility. Epicotyl dormancy, where the radicle begins growth but not the plumule, can be broken by keeping rooted seeds at a cool temperature, usually between 40° and 50° F. for a few weeks. A series of papers by members of the staff of the East Mailing Research Station, on the occasion of the Association's annual conference hi September 1938, is also included in the volume.
