illustrations showing the development of the worms and the production of 
galls on the plants. C.P. Close (N. Y. no. 161: 153-164. 2 J.) records 
three season’s tests in successfully combating’ gooseberry mildew with potas- 
sium sulfid, and less important results with Bordeaux mixture, lysol, and 
formalin. A popular two-page edition of this bulletin has been prepared by

ANNUAL REPORTS of experiment stations published during the year 1899 
not yet mentioned in these pages but containing matters of interest to bota- 
nists, may now be briefly noticed. In the nineteenth report of the New Jer- 
sey station B. D. Halsted-(pp. 289-370, 72 #/.) fills eighty pages with the 
results of a wealth of observation and experiment, supplemented with a 
dozen well printed plates. Lime is found to be effective in checking club- 
root (Plasmodiophora) of turnips, and sulfur ineffective; the latter, how- 
ever, when applied to the soil outranked corrosive sublimate in reducing the 
scab of: potatoes; and it is even more serviceable in case of sweet potatoes. 
The fungicides, Bordeaux mixture, cupram, soda-Bordeaux, and creolin, were 
used with varying results upon beans for Colletotrichum lagenarium Pass. 
and Bacillus Phaseoli Sm., on tomatoes for Cladosporium fulvum Cke., on 
spinach for a Cladosporium and a Phyllosticta, on egg-plants for Phy/los- 
ticta hortorum Speg.,on cucumbers for Colletotrichum lagenarium Pass., and 
on beets for Cercospora beticola Sacc. Fungicides were also used on other 
plants with less conspicuous results. The smut of onions, Uvocystis Cepule 
Fr., was introduced into a plat by bringing soil from another part of the state 
which had borne a smutted crop the year previous. There are observations 
upon asparagus rust, and on other parasitic fungi, on shading plants, on 
weeds, and on a number of other topics. The report closes with a discus- 
sion of the relation of fungi to weather. ; 
Spot diseases of tobacco. There are also seven pages of miscellaneous 
notes on plant diseases and spraying. In the same report E. H. Jenkins 
(pp. 310-316) gives statistics on the germination of garden seeds of various 
ages.
