(Nos. 9 and 10 are good elementary works on Insects; No. 4 
is the best book of reference on fruit pests, while No. 15 is an 
elementary outline of the same subject; Nos. 7 and 13 are reports 
on various species of injurious Insects and other animals; No. 17 
is a general book on pests of fruit and vegetables and, although 
out of date, contains useful information; Nos. 1 and 2 deal with 
the economic status of Birds, and No. 19 with the encouragement 
and protection of the beneficial species. The remainder of the 
references deal for the most part with special subjects referred 
to in these lectures.)
