leaves, flowers and buds, seed vessels, &c, and attention called to the 

 details most likely to be of value to the student. In spite of special 

 assistance to keep the author "within the bounds of botanical accuracy," 

 the names attached to the drawings are the weakest feature in the book. 

 Fig. 53 — " Wild mint " is not a mint. Fig. 54 is not the Arbor-vitae. 

 Fig. 55 — The seed pods drawn are not those of Primula vittata. Figs. 33, 

 49 } 61 — The helminth and nipplewort are included as sow-thistles. Figs. 

 54, 55 and 57 — Six distinct plants, including the Lucerne, Medick and 

 Lotus, are all named "Vetch." Drawings of the Milk and Nodding 

 thistles are not named at all. Fig. 59— Oak and acorns includes four 

 species of Oak. In view of the rather gratuitous criticism of botanists 

 and gardeners, we fail to understand the use of the name " Biscutella " 

 for the buckler mustard or "the canariensis " for the Canary creeper, and 

 most gardeners, we think, would discredit the statement (p. 99) that the 

 little bedding Calceolaria if not maltreated by pinching would become an 

 elegant plant 5 feet high with flowers of a different shape ! The state- 

 ment on p. 71 that " the connection between seed and root is nowhere 

 more clearly demonstrated than in the onion, where you may see in the 

 seed-head itself actual bulbs beginning already to send out their shoots of 

 green " is surely unintelligible. The author is on surer ground in the first 

 and last chapters, where space is found for a defence of ornament for 

 ornament's sake, although it is already generally conceded that that is 

 truly ornamental which rightly pleases, quite apart from story, symbol or 

 the definite embodiment of natural form. 



" Trees : a Handbook of Forest Botany for the Woodlands and the

Mr. Percy Groom, in bringing out this volume, has dealt with a 

 delicate subject in a commendable way, for it is no easy task to bring out 

 a new edition of another person's book. There is certainly much to 

 commend and little to find fault with in this revised edition — perhaps the 

 most valuable work of its kind that we possess. Not only is the amateur 

 well catered for but the professional in such matters will find much to 

 interest him in the lucid and carefully thought out articles which occur 

 under each heading. The descriptions of the various trees are particularly 

 good, the peculiarities of each being well defined, though, as was necessary 

 in a handbook of this kind, much condensed. Altogether we can highly 

 recommend this book on trees, and the numerous well-executed illustra- 

 tions go far in elucidating the text. 



"Fruit Trees and their Enemies, with a Spraying Calendar." By 

 S. Pickering, M.A., F.R.S., and F. V. Theobald, M.A. 8vo., 113 pp.

A most useful little book has lately been published on spraying fruit 

 trees with fungicides and insecticides. The joint authors, Mr. Spencer 

 Pickering and Mr. F. V. Theobald are both well-known experts in the 

 matter of enemies to our fruit crops. In some general remarks upon 

 spraying the authors give, on page 2, some good advice. " Spraying, 

 to be successful, must be done intelligently ; the grower must know
