672 THE AMERICAN NATURALIST.  [Vor. XXXVI. 
in the hands of subscribers, and the early spring of 1902 sees the con- 
cluding volume in print. What has been said earlier in the Maturalist 
about the quality of the first three volumes applies equally well to 
the one now issued. . Whether the work be consulted by the gardener 
for cultural methods, by the amateur for the names of cultivated 
plants, or by the schoolmaster for information as to the horticultural 
resources and possibilities of a given state or territory, it will be 
found to offer a ready answer to most questions and to indicate how 
the more obscure ones may be answered by one having the patience 
to follow them up. Throughout the Cyclopedia the personality of 
its editor is manifest, although very many of the articles have been 
written by others; and perhaps the most interesting reading in it is 
the introduction to the fourth volume, in which, from his own pen, 
we learn how the work was conceived, planned, and executed. The 
Cyclopedia is a notable piece of book making, and it is gratifying to 
know that the editor hopes, by means of annual supplements, to 
round it out with analytical keys for the determination of genera, — 
which in the body of the work are alphabetically arranged, — an 
extended bibliography, and the current chronicles of horticultural 
change. W. T.
