GENERAL NOTES. 
BOTANY .! 
ILLUSTRATIONS or Nortn American Ferns. — It gives us sincere 
pleasure to learn that it is proposed by Mr. S. E. Cassino to publish 
an illustrated popular work on our ferns. The announcement is made 
that the drawings will be from sketches by Mr. J. H. Emerton, and that 
the text will bé furnished by Professor Eaton. The latter is a recog- 
nized authority thoroughly familiar with American ferns ; Mr. Emerton’s 
skill as a draughtsman is well known to our readers. The plates are 
to be in color, and the work is promised at an exceedingly low price. _ 
ACER pasycarpum. In 1843, Mr. Emerson measured a tree of this 
Species, growing in the town of Stockbridge, Mass., when at three feet 
the ground, it girted twelve feet. In October, 1876, the same tree 
was measured by Mr W. R. Robeson, who reports that its cireumference 
at the same height, was then fifteen feet and nine inches, showing an 
annual average increase of circumference during the last iain 
years of a little over 1.36 inches. — C. S. SARGENT.
