the remainder of the flower are shown in 
the way of a shrunken style and stigma, in 
the open and empty anther sacs which con¬ 
tained the pollen and in the somewhat larger 
receptacle. Now let us examine plate No. 
IV. In this we find that the sepals are turn¬ 
ing inward, due to the enlargement of that 
part of the original flower in plate No. I, 
termed the receptacle. It is the receptacle 
of the flower which develops into the edible 
portion of the apple as shown in plate No. 
II, and the corresponding parts in plates 
Nos. V and VI. 
Our rules for spraying for the codling 
moth tell us that the first spraying should 
take place immediately after the petals fall, 
and that the calyx (the sepals taken togeth¬ 
er constitute the calyx) should be well filled 
with the poison. From an examination of 
plate No. IV it can readily be seen that the 
turning-in of the sepals as the little apple 
develops from the flower directs a spray 
away from the calyx cavity. A few days 
later in its development the sepals form a 
sort of cone-like roof over the calyx cavity 
much like that of a mature apple, as shown 
at “c” in plate No. V. It can also be seen 
by a close examination of plate No. II that 
the larva of a newly hatched moth has but 
a small distance to eat to reach the center 
of the little apple during the early stages 
of its growth. It is also noticeable that the 
calyx cavity during the early stages is quite 
pointed; hence, if the poison is well placed 
during spraying, the larva is sure to eat it in 
its endeavor to reach the inside of the apple. 
Thus we find that each part of the flower 
after unfolding from the bud gradually
