Hydrangea.

 In the greenhouse on the college grounds some hydrangea
cuttings were put out to be rooted. Only a very small portion
of the cuttings lived; examination showed that a fungus seemed
to be the cause. The greenhouse had been used for studying
tomato blight during the summer, and the soil had been pretty
thoroughly seeded with blight. Later tests, with pure culture of
blight, showed that hydrangeas are subject to this disease.
 WEEDS ATTACKED.
 Desmodium molle, or beggar weed, is killed by blight, but
does not propagate it to such an extent as some other plants,.and
it is a question whether serious damage would be done for more
than one year.
 The fire weed, Erachtites hieracifula, is very severely attacked,
and propagates the blight to a remarkable degree. This weed is
very common on new land and on land just being prepared for
cultivation, as well as on sparely timbered land. It is a com-
mon weed in Florida, but not at all troublesome excepting that
it makes a good fire weed. It catches fire easily and makes a
quick, hot blaze.
 Another common weed, the Canada fleabane, Erigeron Cana-
dense, also called cow-tail, is severely attacked by the tomato
blight. The habitat of this weed is much the same as that of
fire weed, besides taking possession of old fields and of neg-
lected fields.
 Two of the amaranths, or careless weeds (A. retroflexus, L.
A. spinesus, L.) are also killed by tomato blight.
 There are many other weeds that may be added after further
study. It has already been stated that there are a number of sus-
pected hosts not mentioned here. From the above list we see
that this parasite has quite a faculty for adapting itself to differ-
ent hosts.
 HOW BLIGHT WINTERS.
 We have seen how this blight may live from early spring
until late fall by simply attacking one plant, and then another,
