nard, wild sarsaparilla, sumac (everal species), rose haws, 

 sorrel, ragweed, grass and asparagus. The list shows how 

 little the bluebird depends upon the farm or garden to 

 supply its needs, and indicates that by encouraging the 

 growth of some of these plants, many of which are highly 

 ornamental, the bird can be induced to make its home on 

 the premises. 



Bluebirds are so well known that it seems unnecessary 

 to urge anything more in their favor ; but in view of the 

 fact that large numbers were destroyed during the storm 

 of 1895, more than ordinary vigilance should be exercised 

 in protecting them until they have regained their normal 

 abundance.

High School Botany. ^ — In any new edition of a text-book one 

 naturally seeks to discover (1) what extensions have been made, and 

 (2) how far the errors and objectionable features of earlier editions 

 may have been corrected. 



The first part of the book before us, embracing 226 pages, is devoted 

 to tlie general principles of Morphology and Physiology, with a discus- 

 sion of type forms of the lower groups of plants, ranging from a fern to 

 Chara. The principles of classification are also dealt with, and the 

 three concluding pages are devoted to directions for the collection of 

 plants and the formation of herbaria. In this portion of the book no 

 extension or alteration has been made ; it remains as in the previous 

 revised edition of 1887. 



The second part, dealing with the Flora of Canada, has been 

 extended from 162 to 271 pages, and now "includes most of the wild 

 plants of Manitoba and the prairie region generally, as well as those of 

 the older pr6vinces." We observe also, the introduction of a separate 

 and much better glossary, and an alphabetical list of common cultivated 

 plants, which are designated by both common and scientific names. It 

 is in this portion of the book that we note the only extensions and
