mation gathered by Mr. Roth, are as follows: (1) the appointment of a per- 
manent forest commissioner or commission and a fire warden with suitable 
powers ; (2) state control of the manner of exploiting the forest resources; 
(3) the acquisition of forest lands by the state at their market value, to be 
paid for in non-taxable scrip bearing 3 per cent. interest, payable after 
thirty years in yearly payments equaling so per cent. of the principal and 
accumulated interest; and (4) the good management of these lands by the 
employment of technical skill. To the latter end it is recommended that 
instruction in forestry be provided at the state university.x— C. R. B 
Dr. J. C. ARTHUR describes in Proceedings of the Indiana Academy of 
Science for 1897 a simple arrangement for securing uniform water power for 
use with physiological apparatus. He uses a tank, set in the upper story of 
the building, and kept filled from the city water supply by an automatic float 
valve, such as is used for water closet tanks. A small lead pipe, which can 
be put in place without skilled labor, siphons the water over the top of the 
tank — he uses a barrel—and is closed by a piece of rubber tubing anda 
pinch-cock below. A head of fifteen feet is sufficient to run a water motor 
which will drive acentrifuge. The uniform pressure is useful for many other 
purposes.—C, R, B. 
Dr. A. J. Grout has prepared a list of the mosses of Vermont repre- 
sented in the collections of Messrs. C. C. Frost, C. G. Blanchard, C. E. and 
E. Faxon, G. G. Kennedy, Mrs. E. G. Britton, and the author.4 Dichoto- 
mous keys to both genera and species are provided, so that determinations 
are much facilitated. A number of species, reported but not known to be 
represented by specimens, are enumerated in a separate list. The arrange- 
ment of families and the nomenclature are modernized.—C. R. B. 
THE NUMBER of species and varieties, not to mention the forms and sub- 
forms, of Sphagnum has §rown so great and the synonymy is so intricate and 
confused that it is almost impossible for even a bryologist who is not 4 
sphagnologist to find his way through the maze. M. Jules Cardot, an able 
student of this genus, has rendered his fellow bryologists a most acceptable 
service by publishing a catalogue of all the species and varieties, giving the 
synonymy, bibliography, and geographical distribution.’ It is based upon 
the most recent work, especially upon Warnstorf’s comprehensive studies.
