and has spread widely. It adds the quince and pear to 
its bill of fare. It is double-brooded, and very injurious. 
The moth lays her eggs singly on the blossom end of 
the fruit, where it hatches in a few days, and burrows 
for the cere, feeding asit goes... In three or four weeks 
it is full grown. and crawls out of the fruit to seek a 
place to spin 1‘s eccoen end pupate, coming out with 
wings in ten to fifteen days later. The second broods 
do not issue as motlis till the next spring. 
Remedies.—Spraying the trees with any of the arsen- 
ical poisons when the frnit is small, is most relied on to 
destroy the larva before they get into it. Those that 
escape and mature in fallen fruit are trapped with bands 
placed around the trees. Where there are plenty of 
apples, other fruits are little sought; but in western 
New York, where quinces are largely grown, the codlin 
moth is a very serious enemy. 
CHAPTER XXI. 
SOME FUNGI INJURIOUS TO THE QUINCE. 
BY DR. BYRON D. HALSTED. 
In this chapter the reader’s attention is called to a 
group of enemies of the quince that consist of minute 
plants. Fungi are usually so small that they can only 
be seen with the microscope, and consist of fine threads 
which run into the substance of the quince stem, leaf 
or fruit, and rob it of its vital juices. The spores they 
produce are minute bodies, capable of growing into new 
fungi when conditions are favorable. Spores serve the 
same purpose for fungi that seeds do for higher plants. 
The orchardist’s attention is called to those kinds of 
fungi that have proved to be the most destructive to 
guinces, 'eaving out of sight a large number that occur
