" If you do not think it safe to hum the vines on a hog, do you helieve 

 they coidd he cut, raked off and burned, without injuriyig the roots, even 

 if left uncovered by the water during the winter? " 



85 per cent answer yes ; 15 per cent, no. Some think it will 

 depend much on whether the winter is mild or severe. 



" What do you think would be the cost per acre to cut, remove, and 

 hum the vines? " 



The answers range from $5.00 to $100.00, but the majority range 

 from $5.00 to $15.00. 



The object of the last seven questions was to learn whether a badly 

 infested bog could be cleared of the insects at a moderate cost with- 

 out destroying the roots of the plants ; and how much time would 

 elapse before it would bear again. In case of a somewhat isolated 

 bog, this might pay, but if it be near one that is infested, it is doubt- 

 ful if it would prove a success. 



When a new bog is made it is very important that vines to restock 

 it should be obtained from some bog which is not infested, as they 

 are set out at a time when the eggs of the vine worm are on the 

 leaves ; and if the vines are obtained from an infested bog, the new 

 one will be stocked, not only with plants, but with insects also. 



From the replies received and from my own observations on the 

 bogs over the entire Cape, it seems that the vine worm does by far 

 the greatest amount of damage, and that the fruit worm stands next 

 in the list. The span worm is occasionally quite destructive, but I 

 found only two bogs last summer on which it had done much damage ; 

 one at Pleasant Lake, owned by Mr. Cyrus Gaboon, and one in 

 Carver,. under the supervision of Hon. A. D. Makepeace to whom I 

 am under obligations for much valuable information. Specimens of 

 the span worm were sent here to the Insectary, but the studies on 

 them have not yet been completed, and therefore no report can be 

 made on them at this time. I recommended the application of Paris 

 green in water, one pound of the former to 150 gallons of the latter, 

 and two quarts of glucose or molasses. The object of the glucose 

 was to cause the Paris green to adhere to the leaves and prevent it 

 from being washed off so readily by showers. Mr. Makepeace has
