 following up. 



" Submerged Forests." By Clement Reid. 8vo., 129 pp. 

 (University Press, Cambridge, 1913.) is. net. 



Not a little interest attaches to the submerged forests which are 

 so numerous round our coasts, and which occur as well, strangely 

 enough, in the middle of the North Sea, on the well-known Dogger 

 Bank. The reviewer well remembers the interest he felt in examining 

 the moss remains in the " moor log " from this ancient forest, and find- 

 ing plants not only British but also others confined now to Continental 

 Europe. The author gives an account of these strange relics in a 

 very interesting way, and as only one could who has devoted an 

 immense amount of patient investigation to the remains found in them. 

 Like all the " Cambridge Manuals," this is a reliable and well- written 

 guide to a special branch of knowledge. 



" Toadstools and Mushrooms of the Country Side." By Edward 

 Step, F.L.S. 8vo., xvi -f 143 pp. (Hutchinson, London, 1913.) 

 5s. net. 



One hundred and thirty-five photographic plates, some of them 

 coloured, form the bulk of this book, which is intended for the pocket. 

 Notes descriptive of the fungi illustrated and their near allies, with 

 an account of their habitats and properties, form the letterpress. The 

 book will prove an interesting companion on a ramble in the autumn 

 or winter woods. Only the larger forms of capped fungi are dealt 

 with, and the author promises a further instalment dealing with the 

 puff-balls, earth-stars and so on, if the present one meets the success 

 it certainly deserves. One little criticism we may be allowed to offer. 

 Is it really incumbent on the author to coin " common " names ? 

 Is Amanita spissa commonly known as " Heavy Toadstool," or Lepiota 

 excoriata as " Flayed Parasol," or Clilocybe phyllophila as " The 

 Leaf-Lover," or Russula furcata as " Fork-gilled Russule " ? 



" Clay's Successful Gardening." Ed. 5. 8vo., 331 pp. (Clay, 

 Stratford, 1913.) is. net. 



A great variety of gardening matters is dealt with by well-known 

 writers, and much valuable information is given on the growing and 

 showing of all kinds of plants. 



" An Introduction to the Chemistry of Plant Products." By 

 P. Haas and T. G. Hill. 8vo., xii -f 401 pp. (Longmans, Green, 

 London, 1913.) ys. 6d. net. 



We are thankful to the authors for bringing together within the 

 covers of one volume the material here collected. All serious students 

 of physiological botany will find it a valuable aid, especially as refer- 

 ences are given to the chief literature and bibliographies under each 

 of the groups of substances treated of.
