noted (1) for its trout, (2) for the abundance and variety of repre- 

 sentatives of the mosquito tribe. "Insect powder,"or pyrethrum, was used 

 with great advantage, and the simple act of burning a snail pile of this 

 substance in the room quieted every mosquito and afforded an excellent 

 opportunity of enjoying a good sleep, which it would otherwise have 

 been impossible to obtain. He had just returned from an expedition 

 to the locality mentioned with the eminent American entomologist, Mr. 

 :S. H. Scudder. They had gone to collect the eggs of some rare butterflies 

 and had been very successful, having secured eggs of no less than 14 

 species. An important investigation now being carried on was with 

 reference to the timber-boi'ing beetles. The life -history of these insect 

 enemies, which destroy annually a large quantity of timber, especially 

 that which has to remain in the woods after being cut for a season or 

 two, was not yet fujly known, and a link was necessary to complete the 

 chain of our knowledge regarding them. He was of the opinion that if 

 the time and manner in which the beetles laid their eggs, whether on the 

 sui-face or in crevices and holes of the bark, or in other ways, as had been 

 variously stated, were accurately determined, a remedy might then be 

 found. If the beetle as is supposed by some, gnaws a hole in the bark 

 in which she lays her eggs, it is possible that the old reliable poison, 

 Paris green,^as had been suggested to him by Mr. J. M. Irwin, of 

 Peterboro, might be useful in poisoning or deterring the insects from 

 depositing eggs oa logs protected by this substance. In a knowledge of 

 the life history of an insect lies the secret of success in the work of an 

 economic entomologist. 



At the request of Professor Saunders, Mr. Henry M. Ami, 

 of the Geological Survey staff", and leader in geology of the O.F.N.C., 

 was called upon to give an account of the geological features which 

 characterized the farm, a subject which had engaged his attention for 

 some time past. Mr. Ami began by stating that the rocks which were 

 found on the farm belonged to two great periods or systems in geology, 

 widely separated in time and differing in many characters. The older 

 and underlying series had been deposited in palasozoic times, a period 

 long anterior to the advent of man or p.ven of mammalia upon the earth. 

 The limestones which were seen to cro[) out in various places contained 

 many remains of fossils entombed in them, such as trilobites, encrinites
