appeared afterwards was free from caterpillars, showing that the 
application was satisfactory. 
“ Six females, eight males. 
“ No. 7.—i \ T ot Syringed with any insecticide, 57 inches circumfer¬ 
ence. One hundred and thirty-eight females, one hundred and three 
males. Bore two Apples only. 
“No. 8 .—Not syringed with any insecticide, 34 inches circumfer¬ 
ence. Eiglity-two females, eighty-five males. Bore about half a peck 
of Apples. 
“ No. 9.—Tree partly syringed with London-purple, early before 
buds expanded. The portion of the tree syringed bore a nice crop of 
Apples of good quality ; foliage good. 
“The portion of the tree not syringed bore very little fruit, and 
the foliage was very badly damaged. 
“ Grease bands; about two-thirds of the trunk banded with water¬ 
proof paper, on twenty-seven inches of the circumference, eiglity-five 
females, fifty-three males. 
“Nine inches of the bark was dressed direct (without any paper), 
on which two females and two males only were caught, thus showing 
the effect of absorption of the sticky part of the dressing by the 
bark.”—(J. H.) 
To the above report Mr. Hiam added the following summary:— 
“Six trees syringed, on which were placed 128 in. of bands. 
Moths caught, females 17, males 69. 
“ Three trees, two of which were unsyringed, and one partly so. 
118 in. of band. Females caught 305, males 241.” 
Looking at the season’s work as a whole, also from the well qualified 
opinion given by Capt. Corbett on the careful trials at Toddington, and 
opinions sent me in reply to my successive reports, by the Dominion 
Entomologist of Canada, I consider it cannot be looked on as other 
than a success. 
We had many failures. These must be always expected in trying 
new measures, but we can trace these very especially to want of 
apparatus, and also notably to the proportions advised not being 
adhered to. There was an alarm as to leaves of trees dropping, but so 
far as report has been given me, and special report was sent at my 
request, this was for the most part where over-quantity of the chemical 
was used. 
Rather unfortunately for our steady progress, an experiment was 
made by one observer of giving an enormously strong overdose, which 
application was crowned with the fullest success. The caterpillars were 
killed and the leafage was uninjured. The reason of this was easily 
traceable, to the fact of such rainfall as washed the leafage clean 
almost immediately following; but meanwhile, encouragement was
