TIIE CANADIAN ENTOMOLOGIST. 149 



and by the 6th of September many of them were full grown. With us they 

 were much more destructive to cherry trees than to pears, consuming the 

 upper surface of the leaves, some giving the trees a scorched and sickly aspect, 

 in many cases the foilage fell off, leaving the trees almost bare. 



As soon as the slugs were observed at work in Spring, they were treated 

 to a plentiful supply of dry sand thrown up into the higher branches with a 

 shovel, and shaken over the lower ones through a sieve, which stuck thickly 

 to their slimy skins, completely covering them up. Thinking we must have 

 mastered them by so free a use of this long trusted remedy, we took no further 

 heed of them for some days, when to our surprise they were found as numerous 

 as ever. The next step taken was to test this sand remedy accurately to see 

 what virtue was in it. Several small branches of pear trees were selected and 

 marked, on which there were six slugs, and these were well powdered over — 

 entirely covered with dry sand; on examining them the next morning it was 

 found that they had shed the sand-covered skin and crawled out free and 

 slimy again. The sand was applied a second and a third time on the same 

 insects with similar results ; and now being convinced that this remedy was 

 of little value, they were treated to a dose of hellebore and water, which soon 

 finished them. Ashes were now tried on another lot, the same way as the 

 sand had been, with very similar results. It was also intended to try fresh 

 air-slacked lime, which we believe would be effectual, but having none on 

 hand just then, the experiment was postponed, and the opportunity of testing 

 it lost for the season. We must not omit mention of an experiment with 

 hellebore. On the 13th of August at 8 a.m. a branch of a cherry tree was 

 plucked, on which there were sixty-four slugs; the branch had only nine 

 leaves, so it may be readily imagined that they were thickly inhabited. A 

 dose of hellebore and water was showered on them about the usual strength, 

 an ounce to the pailful, when they soon manifested symptoms of uneasiness, 

 twisting and jerking about in a curious manner ; many died during the day, 

 and only six poor sickly looking specimens remained alive the following 

 morning, and these soon after died.
