winter with a dormant spray, and under such conditions the scale 
is of littl* importance. Although the San Jose scale is probably 
our most important fruit-tree pest, ^e find that most of the trees 
are able to survive many years even though infested with this insect. 
Of course, young small trees that become infested frequently succumb, 
but after the trees have survived to an age of three or four years, 
they are usually able to survive for a much longer period. These 
trees, of course, are probably not so vigorous and profitable as 
trees that are sprayed and kept practically free of scale insects, 
but I have on numerous occasions observed trees to remain infested 
with the scale for many years and continue to bear quite profitable 
crops from year to year. It would seem that in many cases this is 
due to partial natural control of the insects combined with the 
resistance of the trees. Our nurseries are kept free of the scale 
and no trees are allowed to be sold under any conditions that show 
scale markings. As a precautionary measure all deciduous trees are 
fumigated with hydrocyanic-acid gas, but any that show scale markings 
must be discarded. 
Louisiana W. E. Hinds (February 17): The San Jose scale is undoubtedly serious 
wherever it occurs, and we have no doubt that it had continuous 
breeding through the winter season. 
Colorado C. P» Gillette (February 16): T7e have had no inquiries concerning 
the San Jose scale during the past year. Te know, however, that the 
scale does occur in some of the orchards in the vicinity of Grand 
Junction, and probably there is some extremely slight infestation 
in one locality in Delta County, but for the past two years we have 
been unable to find any specimens of it at all. In the Grand Junction 
area we try to treat promptly every orchard where an infestation 
occurs, but have never been $ulte able to stamp the insect out. 
It does very slight damage to the fruit crop in this State. 
Idaho C. lakeland (February 15): Severe infestations of the San Jose scale 
on fruit trees occurred only on trees in areas where there had been 
a small percentage of the insects that survived the winter of 1924- 
25. These areas were known and spraying was carried on generally 
in restricted communities in the spring of 1926. As reported in 1926, 
very little dormant spraying was done in the spring of 1925, and it 
was not needed, for the winter preceding had killed the insects 
completely in the fruiting areas of and on all portions of the trees 
above snow line. Killing was so complete that in large areas there 
has not been sufficient increase of scale insects to justify the 
application of dormant sprays again in 1926. There are a few localities 
even where it appears that spraying will not be conducted this 
seacon, so complete was .the destruction of scale insects in December, 
1924. During the past season a noticeable increase has taken place 
in all areas ^here there was a slight hold-over of live insects 
in 1924-25. In many localities there was little or no injury to fruit 
during 1926, but the insects are scattered in the fruiting areas 
of many trees now where they are not suspected by the grower, and
