Abundance x Wolf which have fruited several years. We have varying
degrees of hardiness in these seedlings. Most of them have withstood our
winters at the fruit farm without injury, as well as in most of the
southern half of the state.
Among the Abundance x Wolf hybrids eight of the seedlings are only
partly hardy, while of the Burbank x Wolf only one or two have shown
themselves to be particularly weak in this respect.
Type of fruit. In general the Burbank type of fruit is dominant. The
flesh of these hybrids runs quite uniformly yellow, varying in degrees,
however, from a deep yellow to a yellowish green. Some of them have a
yellow skin with a blush or a streak of red, while others are a deep red
even before ripe. The fruit in size varies from both smaller and larger
than the parents. Firmness characterises most of the hybrids. We are
also getting good shipping quality, and in Burbank x Wolf No. 12 we have
a plum measuring one and three-quarters inches and more in diameter and
a perfect freestone. This plum will be used extensively in further
plant-breeding.
In shape of tree the two hybrids differ materially. The Burbank x Wolf
hybrids make spreading trees more or less, while the Abundance x Wolf
grows more upright and does not need quite as much room.

TENT CATERPILLAR.--As soon as small nests are detected, they
should be destroyed. When in convenient reach, the nests may be torn out
with a brush, with gloved hand, or otherwise, and the larvae crushed on
the ground, care being taken to destroy any caterpillars which have
remained on the tree.
The use of a torch to burn out the nests will be found convenient when
they occur in the higher parts of the trees. In using the torch great
care is necessary that no important injury be done to the tree; it
should not be used in burning out nests except in the smaller branches
and twigs, the killing of which would be of no special importance. Nests
in the larger limbs should be destroyed by hand, as the use of the torch
may kill the bark, resulting in permanent injury.
Tent caterpillars are readily destroyed by arsenicals sprayed on the
foliage of trees infested by them. Any of the arsenical insecticides may
be used, as Paris green, Scheele's green, arsenate of lead, etc. The
first two are used at the rate of one-half pound to 50 gallons of water.
The milk of lime made from 2 to 3 pounds of stone lime should be added
