only by foliage, was not described in Michaux’s Flora Boreali- Ameri- 
cana, and in the herbarium the sheet had been left among the unnamed 
specimens following those which formed the basis for the F lora. 
The label, “in the bogs of Batiscan," gives the desired clue to the date 
of collection, for on the 14th of July, 1792, Michaux botanized in the 
bogs at Batiscan (in Champlain Co., Quebec) and there collected 
some very characteristic bog plants. His journal of that date reads: 
“Le 14 herborisé a 8 li. de distance des Trois Riv. dit Batiscan; plus 
bas Andromeda polifolia, Kalmia glauca, angustifolia; Azalea glauca 
[?, Ledum palustre [groenlandicum], Comarum...."'! Whether 
or not Michaux's material of Salix balsamifera gathered in 1792 is 
the earliest collection of the species, which is not improbable (although 
this willow is common in eastern Newfoundland and various regions 
of eastern Canada whence early collections of plants were carried to 
Europe), it is obvious that his material was collected thirty-one years 
earlier than Little's specimen from the White Mountains, the speci- 
men which has so often been cited as the earliest collection of the 
species.

Bowman’s Forest Puystocraruy.? — Although written primarily 
for foresters and students of forestry, Professor Bowman's book will 
find an interested circle of readers among students of plant-geography, 
for in it are stated in clear and readable style the general physiographic 
features of the United States, with discussions of soils and climatic 
conditions, and much other matter which bears directly upon the 
distribution, not only of forests, but of other plants as well. The 
field-botanists whose interests lead them to the boundaries of 
physiography and geology are constantly in need of authoritative 
information upon these allied subjects and by them Bowman's Forest 
Physiography will be heartily welcomed.— M. L. F.
