equal to all the others combined. It is very generally known as
mold. The trouble is caused by a minute animal that somehow,
by its presence, causes a white, fuzzy outgrowth on the plant. The
part that appears like mold is not mold at all, but an outgrowth
of the skin of the tomato vine. The term mold has been occupied
in another way, and is erroneously used for this disease, so it would
be well to use some other. In Southern Spain ashy is used. While
this may express the appearance as nearly as mold, the same objec-
tions and not too long.
 Forty-three tests of fungicides and insecticides were made to
find a remedy for this pest, but, as far as could be seen, they
were all equally ineffective. The circumstances were all unfavor-
able, and so the tests cannot be pronounced failures. It is not
at all improbable that some efficient remedy will be found among
the insecticides. Some form of the sulphur insecticides seems
about'the right thing. I believe that it is.claimed that these
destroy by their fumes, and that it is not necessary for the liquid
to come in contact with the animal. This is very important, as
it is very difficult to saturate completely a branch inhabited by
phytops on account of the fine, hairy out-growth entangling so
much air that the phytops can live right along on a submerged
branch.
 As soon as a branch becomes inhabited it seems to stop
 bearing and do nothing but produce friz and feed phytops.
 The life-history and mode of dissemination of this animal,
 I think, are not known. It is probable that if these were known
 it would be less difficult to control it than to cure the disease
 after it has attacked the plant.
 It will require some time and labor before this knowledge
 can be gained, however.
 NEMATODES.

 A very wide-spread disease, and of many different plants, is
 one known as root-knot, or root-gall, caused by H terodera radi-
 cola. It is claimed by a good many careful observers that this
 is not so bad now as it was a few years ago. It does not pay,
 however, to plant tomatoes on land infested by this small ani-
 mal. This disease may be carried from one part of the field to
 another by simply taking the root of some diseased plant there
 and leaving it. There are many of our common weeds attacked
 by this worm, and care should be taken that these are not
