dragged about. If a field is free of it, there is no danger of the
disease, if the commercial fertilizer is used, or if care be taken
not to use any roots in making compost.
 BLIGHT.
 HISTORY.
 The blight of tomatoes in Florida is caused by a fungus
that is indigenous to the State. The term blight is used in a
number of different States for different diseases. In Mississippi
the Southern tomato blight was found by Dr. B. D. Halsted to
be caused by bacteria. In this State there seems to be little or
no confusion as to what disease shall be termed blight. Other
terms are used for this disease, but where this is the case no
other trouble is known as blight. It is probable that no consid-
able portion of the State is free from it. Often it is present with-
out the owner knowing it at all. In Lake County a field con-
tained 13 per cent. of blighted plants without the owner knowing
it. In fact, he was certain that no such thing was in his field.
However, after the blighted plants were pointed out to him, he
was able to distinguish them, and to help to compute the above
results. In Alachua County over 7 per cent. of blighted plants
were present without the owner's knowledge. Only one field of
considerable size has been seen that was free from blight, and
this was one that was in a good state of cultivation and had
been for some time. Many attempts have been made to grow
tomatoes in fence rows ;" i. e., grow them nearer the fence than
can be cultivated; nearly all such attempts have resulted in
failure, simply because weeds that propagated this disease grew
there, and, when killed, left it to attack the tomato.
 In studying the disease last spring a number of fields were
found that were raising the first crop of tomatoes and were as
badly blighted as any of the older fields in the vicinity. One of
these new fields had as much as 70 per cent. of the plants
blighted before any of the fruit was shipped. At first such
cases seemed to defy all explanation, but a more thorough study
made the reason plain and certain. The disease known as
blight will flourish on a number of garden plants, and on a
number of weeds that are common to fence rows, and to old
fields and those not under cultivation.
 PLANTS ATTACKED.
 It is quite certain that a number of plants, on which the
