growth. For fear of poisoning the fruit, many fruit growers omitted to take 

 measures against the slug, in consequence of which, in some sections, this insect 

 increased to an alarming extent, some trees having their leaves completely stripped 

 of their green portions. 



If such a condition recurs in the years to come, where it is inadvisable to spray 

 witli arsenieals, it will be found that handfuls of powdered soil and lime will act 

 as a temporary remedy. 



The slugs reached their full stage of growth (around Grimsby) about June 

 29th of this year, and where they were present in extreme numbers caused consider- 

 able annoyance to the fruit growers, by adhering to the cherries during picking. 

 By July 2nd the great majority of the slugs had disappeared from the trees and 

 pupated in the ground — a few slugs remained on the trees after this date, and an 

 occasional one could be seen on the leaves at any time till the end of the month. 

 The general emergence from the pupa of the adult and the consequent egg de- 

 position began (around Grimsby) on July 28th and continued until July 31st. 

 Field observations record the second appearance of larvae on August 10th. At 

 this time many fruit growers sprayed a second time, using lead arsenate at the 

 rate of 2 lbs. to 40 gallons of water, and, according to the observations made on 

 this insect by Mr. W. H. Wright, who carried on the work at Jordan in my 

 absence, it was not strong enough, as the larvse lived for several days with the 

 leaves well-coated with the arsenate. At the Jordan Harbour Experimental Farm 

 € lbs. to 50 gallons was used with good results, but this made spraying rather 

 expensive. 



Boeing Wasp (Cemonus inornatus, Say). This wasp was in evidence again this 

 year, attacking newly- headed Peach, Plu.m and Cherry trees. No material damage 

 resulted. 



Attacking iSmall Fruits and Vegetables. 



The Cane Bojieh {Agrilns ruHcollis) and the Satvfly {Monoplmdnus ruhi) 

 were reported as afPecting Easpberries this year, the former from the Port Dal- 

 housie District, and the latter from the Stoney Creek District. The Snowy Tree 

 Cricket {Oecanilms niveus) has been abundant again on Easpberries. 



The two Asparagus Beetles {Crioceris asparagi and C. 12 punctatus) have 

 also caused annoyance in certain sdctions. 



A predaceous pentatomid (probably PeriUus hioculatus, Fabr., variety 

 cloAidus, Say), as mentioned by Dr. C. J. S. Bethune in the "Canadian Ento- 

 mologist" Vol. XLIIL, Septr., 1911, page 320) has been very commonly noticed 

 attacking the larvae of the Colorado Potato Beetle. Its presence has attracted the 

 attenlion of many farmers, but its control has not been sufficient to allow the 

 abandonment of the usual arsenical spray for the beetle. 



The Pe.\ Moth (Semasia nigricans) was in evidence this summer, but, in 

 numbers, not to the same extent as some years preceding. It would appear, from 

 general observation, that the late varieties of Peas are the most liable to attack. 

 These are mostly English varieties, such as Yorkshire Hcto, Shropshire Hero, 

 Carter's Daisy and Fillbasket. At the Jordan Harbour Experimental Farm the 

 last picking of early Peas took place about June 30th, and the tirst picking of 

 late Peas about July 8th. 



Both the Zebra Caterpillar (Mamestra picta) and the worm of Pieris rapae 

 were prevalent on the Cabbage this Summer at Jordan, and destroyed a large 

 number of marketable heads. The Eoot Maggot, also on Cabbages, has been most
