disease will flourish, are still absent from the list, but a provis-
ional list, with a brief description of how the affected plants ap-
pear, will be of interest to the tomato growers. No explanation
will be here given as to the manner of proving that this is one
and the same disease, simply because it would require pages to
do so. Such plants as are merely suspected to be subject to this
disease in the field, and have not yet been proven, are omitted.
It requires weeks of careful work to settle whether a plant is sub-
ject to the blight, as the same cause acts quite differently on dif-
ferent plants.



 Tomato.
 When a tomato plant is attacked, if the attack is not too
heavy, it shows itself by the wilting of a single leaf near a head.
This leaf is usually the last fully developed leaf on that branch.
This is a very important point to notice as the other diseases
begin on the lowest or oldest leaves and then gradually work
upward. It sometimes happens that a plant is severely attacked.
In such cases the entire head hangs down as if suffering from
drouth, while other heads of the same plant are looking fine.
Again, it may cause the entire plant to hang down as though
" struck by lightning, as some people call it. Not because it was
thought that any such thing had happened--death is as sure,
however. Some plants, again, will be attacked very lightly, and
then live out a miserable existence. If fruit is formed, it ripens
prematurely, but usually the plant has to devote its entire ener-
gies to keeping alive.
 Plants suffering from blight alone show no spots on any
 part. Pulling the plant up and examining the roots reveals no
 constant characters. The drooping of the leaves and the absence
 of other characters is a conclusive way of telling.
 If some tomato breeder has a fancy variety that should be
 blighted, he can save his variety by making cuttings from the
 wilted tops, if they are not too much wilted, and root these.
 Cuttings may be freely taken if only they are cut eight inches
 above the ground.
 Every vine attacked by blight should be pulled up at once
 and dried; to let it grow is only propagating the disease for an-
 other year,
