the cause or causes of the first trouble being conjectured, and that of the 
second being identified as 7i//etia corona Scrib.; while Ernest Walker in 
the same bulletin (p. 15-31, z fig.) discusses “Treatment for rice smut,” 
showing by tests that a number of fungicidal methods are available, but owing 
to failure in germinating the smut spores their efficiency was not determined. 
A. B. Cordley (Ore. no. 57: 3-15. 7 f/. 7 figs.) gives an account, under the 
title “ Brown rot,” of the injury to fruit in Oregon, due to Montlia fructigena 
Pers., together with a study of the fungus. H.H. Lamson (N. H. no. 65 : 99- 
108. 6 figs.) gives “ Notes on apple and potato diseases in 1898,” with tests 
of fungicides. A. D. Selby (Ohio no. 97 : 31-61. ¢ figs.) presents consider- 
able data upon smut, rust and scab of wheat and smut of oats. The Fusa- 
rium causing wheat scab has been traced to an ascigerous condition, believed 
to be identical with Gibserella Saubinettii Sacc. Results of treatment of seed 
grain to prevent the several smuts, J. F. Hickman being associated with this 
part of the work, are tabulated. A.D. Selby (Ohio no. 104: 201-216. 3. pi.) 
also shows the beneficial results obtained by spraying for peach curl, and 
gives a few notes on crown gall and yellows of peach. The same investiga- 
tor (Ohio no. 105 : 217-235. 2 figs.) publishes “ Further studies of cucumber, 
melon and tomato diseases,” with some account of the fungous and bacterial 
Causes, and the results of spraying. F. A. Sirrine and F.C. Stewart (N. Y. 
NO. 156: 375-396. ¢ f/.) cover part of the same ground with statistics on 
“Spraying cucumbers in the season of 1898.’ A popular description of 
“ The black rust or summer rust” of grains is given by Otto Lugger (Minn, 
NO. 64 535-550. 73 figs.) Methods for “The prevention of the smuts of 
cereal grains, and prevention of potato scab” are presented by H. L. Bolley 
(N. D. no. 37: 363-379. 3 figs.) with some results attained by farmers. H. 
Garman (Ky. no. 81:3-11. 2 fl. 7 fig.) tells of “A method of avoiding 
lettuce rot” under glass by employing a system of sub-watering, and also gives 
the results of “ Potato scab experiments made in 1898” in the use of fungi- 
cides, A. P. Anderson (S. C. no. 38 : 3-15. 5 figs.) writes on “ bd Oh genie 
gus rust in South Carolina,” and G. E. Stone and R. E, Smith (Hatch, Mass. 
no. €1 : 3-20. 2 f/.) write on “ The asparagus rust in Massachusetts.” J.C. 
Blair (Ill, no. 54:181-204. 27 figs.) gives directions for “ Spraying apple 
trees with special reference to apple scab fungus;” S. T. Maynard (Hatch, 
Mass. no. 60 : 3-11) provides formulz for “ Insecticides, fungicides,’ accom- 
panied by a “ Spraying calendar ;" while W. M. Munson (Me. no. 52 - 3-8) 
8ives general directions and formule for “ The spraying of plants.” A. L. 
Quaintance (Fla. no. 46:77-114. 72 figs.) provides a rather full account of 
the strawberry thrips (Thrips Tritici Osb.) and of the onion thrips (Zhrips 
of abaci Lind,). and of the nature of the injuries they cause to plants. G. E. 
Stone and R. E. Smith (Hatch, Mass. no. 55:3-67. /? pl.) give a large 
amount of information about “Nematode worms” (Hederodera _radicola 
Miill.), including historical and experimental data, much of it new, and with
