The Nursery Manual, by Liberty Hyde Bailey, 456 pages, illustrated, Mac- 

 millan Co., price 1^2.50. 



This is really the old reliable manual that we have used and sworn by for 

 thirty years, but it has been rewritten and brought up to date and made one of 

 the Rural Manual Series; that this is the twenty-second edition shows the 

 wide appreciation of the usefulness of this book. Part first is given to the 

 Classes and Kinds of Propagation which includes a discussion of Seeds and 

 Shoots, Propagation by Means of Seeds and Spores, Propagation by means of 

 Separation and Division, and by means of Layers and Runners, of Cuttings, 

 of Budding and Grafting and a long and practical chapter on El ments in 

 Nursery Practice. Part second is devoted to a Nursery list which is very 

 important and fills half of the book. 



The style of the book is terse and clear, an ideal style for a practical book 

 and it is another evidence of the author's versatility that he could write the 

 Holy Earth, What is Democracy, in such wide contrast in style and subject 

 matter. We predict another thirty years of ever widening use and influence 

 for the Nursery -Manual.

 it are short, graphic, dramatic and interesting. Mr. St. Mars knows how to 

 tell a story that thrills and which holds the reader enchained to the end. He 

 also is given to most feHcitous descriptions: "The pin point squeak of a bat." 

 "You know the beautiful little teal duck with gold and green spectacles and a 

 breast fit for a king's lunch." "They flew in silence, and all alone — nine little 

 birds out of the south and the night — over the cold, restless sea towards 

 England. Sandmartin was their name, and Africa was where they had come
