which is troublesome both in the celhir and garden ; in the hitter especi- 

 ally, being very destructive during early spring, preying on the tender 

 shoots ot plants. These are the mice so detrimental to young orchard^ in 

 winter, when they bark the young trees beneath the snow to such an 

 extent as to destroy them as completely as if girdled. liast sunomer a 

 pair of jumping mice (Zapics hudsonius, Zimmerman) were found at 

 Prescott, and although that place is not in the Ottawa district, yet it is 

 so near as to induce the idea that it is not improbable they may be 

 found in this vicinity. We have heard of a pair being taken on the 

 Aylmer Road a few years ago, but nothing accurate is known of the 

 capture. 



In conclusion, we appeal to the members of the Olub to note down 

 any interesting fact that comes before them during the next season of 

 outdoor observations. Much information full of valuable import might 

 thus be imparted to the Club as a body which may appear perhaps 

 ti'ivial to the individual. If members also would make lists of the 

 objects they notice for the purpose of comparison and record the dates 

 of first and last appearance of the rai-e species, these would be very 

 useful. In following out one brauch of natural history any interesting 

 feature of another branch should never be overlooked, as every con- 

 tiibutor to science of local interest becomes to a certain extent a public- 



lienefactor.

Mr. R. B. Whyte said the refuse from tan vats was quite sufiicient 

 to kill fish, and there was a tannery emptying into St. Louis Dam. He 

 stated that in former years a creek ran down Mosgrove street, on which 

 a tannery was situated, and that every time the vats were emptied 

 numbei's of tlead fish were seen in the creek. 



Mr. Fletcher said that the kangaroo mouse had been found near 

 Aylmer, and that ho had, in the month of January, seen frogs moving 

 about in the canal near the Bank Street Bridge, in a [)Ool possibly kept 

 open by a warm spring.
