_Remedies._--The waste lands for a half mile at least all around the
vineyard should be plowed and harrowed in the early spring. This will
destroy the eggs of the grasshoppers, and the fallow land will serve as
a barrier over which the grasshoppers do not readily pass.
If the vineyards are so situated that the weeds or natural vegetation on
the land surrounding the vines can be burned for half a mile or more,
this will also prove a certain barrier for the hoppers.
A mixture of fifteen pounds of white arsenic with eighty pounds of bran
and twenty pounds of middlings, moistened with enough water to make a
paste, will be eaten by the grasshoppers. The paste is spread on bits of
shakes or shingles and distributed all around the vineyard, and later on
in the vineyard. It may also be smeared on fences or trees. The
grasshoppers will eat it readily, and can thus be successfully
destroyed. If this method is used in time, the advancing army of the
pest can be kept back or destroyed at the very entrance of the vineyard.
As another remedy, a spray is recommended consisting of one ounce of
Paris green, one hundred gallons of water, and two pounds of paste. This
is sprayed on the trees or vines, and is said to kill the grasshoppers
effectively without injuring the fruit.
THE RAISIN VINEYARD.
PLANTING.
_Distances for Muscat Vines._--An examination of the various vineyards
in any or in all the different raisin districts will not help us much in
deciding upon how far apart the vines should be set, as most vineyards
have been planted by men of no previous experience in the raisin
business, and when that experience was at last acquired the vineyards
were already established and could not easily be changed. In planting,
we are too apt to do as other people do without first inquiring from
them if their experience has not taught them anything else, and if they
would not do otherwise if they had to commence over again. For years the
standard distances between raisin-vines have been eight by eight feet.
Of late years this distance was considered too small, as our soil was
supposed to be so rich, that all that was required, in order to get
large crops, was to give the vines plenty of room. Many vineyards have
been set nine by nine, nine by ten, ten by ten, or even ten by twelve
and twelve by sixteen feet. The effect has, however, been different from
that which was expected. Instead of producing larger crops, those vines
which were given more room produced only more wood and more leaves. They
followed that law of nature, which causes any animal or vegetable to
grow luxuriantly when overfed, and which, on the contrary, causes seed
and fruit to form when the vegetable system is restricted to certain
proportions, which, of course, we can only determine by actual
experience. By giving the vines less space, some inconvenience will be
experienced in working the soil, and in drying the crop between the
rows.
