Mr. Pammel's paper is a valuable one, but too long for a synopsis 
here, as are also the two remaining ones. 
Arbor Day Literature. — This annual tree planting day, which 
has spread from the place of its origin on the Nebraska plains east- 
ward to niany of the States, has given rise to a number of books, the 
latest of which is the neatly bound and printed volume, "Arbor 
Day," by E. W. Furnas. It makes no pretence to profundity, nor 
poetry, but gives in sketchy way the history of the tree planting 
movement in the West, with appeals for the growth of trees for 
beauty and for profit, and includes lists of those most valuable for 
various regions, with practical suggestions as to methods. The 
book is dedicated to and contains a fine portrait of the *' author of 
Arbor Day." Mr. J. Sterling Morton, of Nebraska. It is a pretty and 
pleasant contribution to the literature of a part of botany too often 
neglected or ignored by botanists. 
Another School Botany.— Verily in botany " of making many 
books there is no end," and if one Avere obliged to study some of 
them he might well say with the wise man of old, '' Much study is a 
weariness of the flesh." 'J'he last work to claim attention is one 
with the ambitious title of " Botany for Academies and Colleges, 
consisting of Plant Development and Structure from Seaweed to Cle- 
matis," by Annie Chambers-Ketch nm, and brought out by the house 
of J. B. Lippincott Company, of Philadelphia. 
The book is a book of definitions, and often not good ones at that. 
In the first paragraph we read that '' Natural Science treats of all 
things in nature. Nature is a synonym for the Universe," and par- 
agraph 5, '' The plant is the vital link between the mineral and the 
animal. Plants feed on minerals and digest them into organic 
food." The style is sometimes rather lively, as, for example, in a 
note on zoospores (p. 7), ''These little creatures are very social ; 
they dance among themselves, circling merrily, but never jostling ; 
no human dancers could be more polite ; then when the heyday of 
youth is over, they withdraw their cilias {sic), produce an outer w^all, 
send out root-like projections, and develop into staid mother 
plants" ! !
