least expense has been the object in view. The writer believes that 
by the intelligent use of the methods herein given the moth can be so 
well controlled that the injuries will be between 2 and 10 per cent. 
With the insect under control, it will not be necessary to use all of 
these measures every year. 
The writer has never had the opportunity of putting all of these 
recommendations into practice in one orchard. This would have been 
done had it not been for the freeze of 1901. Advice was given many 
times as to the treatment of orchards and the results were noted as far 
as possible. Some of the successes are here given: 
M. A. Kurtz, Nam pa, Idaho, has an orchard of about 2,500 trees, 
many of which are stunted partly on account of lack of care. In 1898 
there was less than a full crop, about 50 per cent being damaged; in 
1899 there was a full crop, but only 100 boxes of clean apples were 
harvested. In 1900 there was about one-fourth of a crop, and all were 
wormy. In 1901 Mr. Gibson, in charge, began good cultivation, spray- 
ing, and banding. There was probablj- over a half crop. The trees 
were all sprayed with Paris green four times, and a majority of them 
a fifth time. Bands were well attended to. The writer visited the 
orchard frequently during the season, the last visit being made the 
latter part of September, when the fruit was estimated to be damaged 
as follows: Ben Davis, 5 per cent; Steele's Winter Red, 10 per cent, 
and Blue Pearmain, 25 per cent. A few Ben Davis trees showed 10 
per cent of damage. A large amount of the fruit was undersized. 
The writer could not get figures after the crop was harvested, but he 
believes the work done against the codling moth was quite successful. 
The only cause of uncertainty was the fact that the crop was small 
the year before, and the insect might possibly have been reduced 
on this account. 
Hon. Edgar Wilson has an orchard (PI. V) near Boise, containing 
about 1,000 trees, about 2,000 of which were bearing. There was a 
light crop of Jonathans and about one-half crop of Ben Davis. Only 
the earty sprayings were made, and they were well done. Bands 
were well attended to. The later sprayings were not made, and the 
bulk of the injury was done by the second generation. Not over 10 
per cent of the apples in this orchard were free from worms. In 1900 
from 85 to 90 per cent were saved. 
Mr. Tiner, of Boise, has about 100 trees, in a badly infested locality. 
Spraying and banding were well done, but only about 30 per cent of 
the fruit was saved. In 1900, 80 per cent was the amount saved. 
The losses in many other well-treated orchards with small crops 
varied from 20 to 80 per cent. In those orchards where the loss was 
higher only partial measures were used. In untreated orchards in 
badly infested localities the loss was always about 100 per cent. The
