However, if it is thought best to try to protect the quince crop, 
the following line of treatment is recommended : Spray thoroughly 
with Bordeaux mixture as soon as the fruit has set, and follow this 
with two or three more sprayings at intervals of ten days or two 
weeks. The young fruit should be protected with the mixture until 
the season of late spring and early summer rains is passed. 
STRAWBERRY LEAF BLIGHT. 
(Sphcerella fragarice.) 
The illustration in Plate IX., Fig. 2, is from a natural size 
photograph of a strawberry leaf that was attacked by the common 
leaf blight or rust. This disease is so common and the characteristic 
spots which it produces on the leaves are so well shown in the illus¬ 
tration that an extended discussion of the nature and effects of the 
fungus will not be necessary. It may attack any portion of the plant 
above ground, and when the leaf surface is materially reduced, small 
berries are the result. The fruiting stems may be so injured by the 
fungus that the berries wither before they ripen, and when newly set 
plants are badly diseased, the future crop may be a failure. Some 
varieties are much more susceptible to attacks of this fungus than 
others, and some valuable kinds have to be abandoned in certain 
localities on this account. 
The degree of susceptibility that a variety exhibits toward this 
disease varies in different localities, but good kinds may be found 
for every locality which are comparatively free from attacks of rust. 
Selection of resistant varieties is the most practical method of com¬ 
bating the disease, but it may be controlled by spraying with 
Bordeaux mixture if it seems desirable to do so. When setting new 
plants, all diseased foilage should be removed and destroyed, and 
the plants should be sprayed a few days after setting. The new 
growth must be protected with the mixture during the fore part of 
the season. This will require about four sprayings. The next sea¬ 
son it is recommended that the plants be sprayed just before they 
blossom and again as soon as the blooming period is over. If the 
plants are to be fruited another season, the beds should be mown 
and burned over as soon as the picking season is passed. If the. 
burning is properly done no harm will result to the plants, and 
many spores of the fungus will be destroyed. 
WHEAT STINKING SMUT. 
(Tilletia fcetens.) 
It is the practice of the wheat growers in many sections of the 
State to treat their seed wheat with copper sulphate (blue vitriol), for
