can have no hesitation in adopting the terms " early stuck together " 
instead of '* monophyllous in the early stages," if that will make the 
idea clearer, for it was precisely my object to show that the term mon- 
ophyllous as applied to the pine was simply a case of the '* early 
sticking together " of the leaves of the plant.

To Botanists.— I have published a Catalogue or Check-List of the 
Phsenogamous and Vascular Cryptogamous Plants of North America, 
containing the names of nearly 10,000 species. It is, so far as I know, 
the most complete list ever published of the plants of this country. 
It contains 112 pages, and will be found of the utmost utility as an 
auxiliary to the successful arrangement of a herbarium, and invalu- 
able for making exchanges.

Botanical Notes* 
Systematic Position of the Bacteria, — In a Review of recent works 
on bacteria, Dr, C. Fisch {Biolog. Centrabl. v., pp. 97-102) shows that 
the assignment of the Schizomycetes to the fungi does not rest upon 
a sound morphological basis, the physological resemblance in the ab- 
sence of chlorophyll not being sufficient of itself to show a genetic 
affinity. The history of development furnishes conclusive evidence 
against the Schizomycetes being connected with the fungi phytoge- 
netically, either as an early form of development or as the result of 
retrogression. The nearest affinity of the bacteria lies unquestionably 
with certain green organisms, Nostoc^ Oscillaria^ etc., included under 
the Schizophyceos or Cyanophyce^; and these form together a natural 
group of Schizophycese, with no close affinity to any group of fungi. 
According to our present state of knowledge, the Schizophyta must 
be regarded as displaying the nearest genetic affinity with the Flag- 
el lata. — Jotirn, Royal Microscope Soc, 
The Filmy Ferns of famaica. — Under this title, Mr, J. H. Hart 
has contributed to the West Indian Field an interesting article to 
which he appends a list of all the Trichomanes and Hymenophylla 
known to inhabit the island of Jamaica — 22 species of the former and 
13 of the latter. 
Forestry Statistics. — At the American Forestry Congress, recently 
in session in Boston, some very valuable statistics were presented 
relative to the timber supply of this country. The land area of the 
United States is placed at 1,856,070,400 acres; total forest area,44o,99o,- 
000 acres; total farm area, 295,650,000 acres. Of unimproved and waste 
lands, including "old fields," there are 1,115,430,400 acres. There 
are 150,000 miles of railway, including side tracks. It has required 
396,000,000 ties for their construction. Supposing that the ties 
require to be renewed once in six years, and that ro,ooo miles of new 
road are built annually; if twenty-five years be allowed as the time 
necessary for trees to attain a size suitable for making ties, then it 
would require 15,000,000 acres of standing timber to supply the an- 
nual demand for them. But with the increase of railroads, it is to^ be 
considered that the annual demand for ties is all the while increasing.
