424 BOTANICAL GAZETTE [NOVEMBER 
MANY BULLETINS of the agricultural experiment stations contain matter 
that borders more or less directly upon botany, or have botanical matter 
interspersed among other subjects, thus rendering them of some interest to 
botanists. Of recent issues of this character are the following: A. D. Selby 
has mapped out the distribution of peach yellows in Ohio (Bull. 72), showing 
it to occur along the shores of Lake Erie in the north and in one county in 
the south part of the state. Considerable information is given regarding this 
disease, and also that of black knot of plum, with remarks upon ‘some other 
diseases of fruit trees. L.H. Bailey (Cornell Bull. 117) figures and describes 
root galls upon apple trees, and also discusses some causes of winter injuries 
to fruit trees. The relation of loss of moisture through the bark to hardiness 
is examined with some original data on the loss of moisture from twigs of 
apple. F. C. Stewart (N. Y. Bull. 101) gives results of spraying potato 
plants, describes the internal browning of the tubers, which was found 
experimentally not to be due to bacteria or fungi, and not tobe transmissible ~ 
to the succeeding crop, and also describes two new stem blights of which the 
cause was not ascertained for one, and for the other a new species of Fusa- 
rium (/. acuminatum E. & E.) was detected. Thomas A. Williams reports 
(S. D. Bull. 48) tests with corrosive sublimate, eau celeste, and Bordeaux 
mixture for prevention of potato scab, the first being found most effective. 
Luther Foster gives results (Mont. Bull. 9) of trials in growing potatoes, 
including treatment for scab. L. F. Kinney (R. I. Bull. 38) treats of the use 
of Bordeaux mixture in preventing the phytophthora disease of potatoes. i 
M. Webster (Ohio Bull. 69) examines the claim that Sporotrichum globulif- 
erum and similar fungi can be used to hold the spread of the chinch bug ™ 
check, and comes to the conclusion that “these fungous diseases, in order 
to work sufficiently rapidly and effectually to benefit the farmer, require 
peculiar meteorological conditions and a superabundance of insects at the 
same time.” In a bulletin by H. H. Nicholson and T. L. Lyon (Neb. Bull. 
44) some good data are recorded on the use of large and small beet seed, 
and also on heavy and light seed. In a bulletin on apple culture by L.F. 
Kinney (R, I. Bull. 37) record is made of the number of flower buds 00 
limbs fully exposed to the light and those in shade on the same tree the 
average of ten examinations, including several varieties, giving ke a : 
upon limbs in full light to 136 buds upon limbs in partial shade. be 
relation of the Burrill cornstalk (bacterial) disease and of corn smut t 0 
cornstalk disease of cattle is quite fully treated in a bulletin by N, S. May 
(Kans, Bull. 58), with the conclusion that both these plant diseases cause no 
derangement or disease in animals. R. J. Davidson (Va. Bull. 50)
