accuracies are too numerous to mention: e. g., node for internode 
(probably) on page 112, growing point synonymous with plumule 
(p. 114), object of experiment stated quantitatively and the ex- 
periment carried through qualitatively (pp. 130-131), further ex- 
perimentation assigned as "reference work” (p. 137), “leaves 
exert an upward pull”! (p. 151), the implication that government 
encouragement of tree planting in the western states is closely 
correlated with transpiration (p.156), the implication that the 
release of oxygen in photosynthesis accounts for the greater 
" purity " of country air over city air (pp. 165-166), the definition 
of pollination as the reception of pollen by the ovules (p. 187), the 
implication that Jack-in-the-pulpit is the same as Skunk Cabbage 
(cf. ''Jack-in-the-pulpit or Skunk Cabbage'"—p. 206, with 
""Toadflax or Butter and Eggs’’—p. 212), and so on. 
On page 153, the old method of shielding a portion of a leaf 
from light by corks, long since shown to be fallacious by both 
King and Ganong, is retained, and the object of this experiment 
in starch-making is stated in the indefinite way, ‘‘To discover 
the effect of light upon foliage.” 
But there are also good points about the book. The device 
on page 59 for exposing germinating seeds to differential water 
supply, the experi t (p. 87) to show, by using eosin and methyl 
green, that the path of liquid up in a parsnip root is different 
from the path of the liquid down, and many of the illustrations— 
notably figures 47, 59, 98, and 115, are excellent. 
The reviewer feels that it is unfortunate for the author and 
for high school pupils and teachers that the manuscript was not 
submitted by both author and publisher to some competent 
botanist or university teacher before being printed. As is usual 
with this publishing house, the date of publication is nowhere 
given, and the reviewer regards this as a serious defect, especially 
in a text book on any science. The press work and binding are 
excellent, but think of omitting an index in the year of our Lord 
one thousand nine hundred and twelve!
