SUMMARY OF DISTRIBUTION AND PRESENT CONDITION. 21 
obscure form of disease as well as to the lime-sulfur treatment. In 
southern California it is particularly troublesome in apple orchards. 
The principal variety of apple grown is the White Pearmain, and the 
comparatively rough bark of this variety makes it difficult to get very 
satisfactory results from the lime-sulfur wash. The varieties of apple 
commonly grown in northern California- — for example, Newton Pippin 
and Yellow Bellflower — are smooth barked, and better results with the 
wash are gained. Taking the State as a whole, Professor \Yoodworth 
says that it will be readily found in at least 25 per cent of the or- 
chards, in injurious numbers in probably 10 per cent in any one year, 
and that from 25 per cent to 10 per cent of the orchards are sprayed 
with the lime, sulfur, and salt wash every year. 
COLORADO. 
The San Jose scale has apparenth T not yet obtained foothold in 
Colorado, but it has been sent to us from Colorado on fruit imported 
from California. The probable explanation is that the fruit regions 
of Colorado are above the climatic range of this scale insect. 
CONNECTICUT. 
The San Jose scale is recorded for at least five localities in Bulletin 
12. The increase of this scale in Connecticut has been pretty rapid, 
and Mr. W. E. Britton, State entomologist, expresses the belief that 
there is now no town in the State which is not infested, tho he may 
not have records from quite all of the towns. It is found very gen- 
erally, at any rate, in all of the larger cities, which are thoroly 
infested. Practically all of the larger orchards are infested, tho per- 
haps only slightly. He. says that there are many orchards and trees 
which are still exempt, but that there is no general region of the State 
where the scale can not be found. 
DELAWARE. 
Delaware, as recorded in Bulletins 3 and 12, became generally 
infested very early. Mr. Wesley 'Webb, secretary of the State board 
of agriculture, now informs us that the San Jose scale occurs in all 
parts of Newcastle County and in approximate^ one-half of the 
orchards. In Kent County there are many young peach orchards, 
and more than one-half of them are infested to a greater or less extent, 
a large proportion of them, however, only slightly so. In the western 
half of Sussex County, along the railroad from Farmington to Delmar, 
nearly half of the orchards are somewhat infested, while in the east- 
ern half of the county from Lincoln southward there are but few 
orchards, and these are comparatively free from scale.
