40 THE REt^ORT OF THE Nu. 19 



The cyaniding process, while it will not save more gold than will chlorination, possesses the 



advantage of saving from 70 to 80 per cent, of the silver values in an ore as well and hence is in 



more general use.

The Mastodon of Mount Brydcjes. 



During the summer there was found on the estate of Mr. Duncan Forbes of Mount Brydges 

 tlie jaw of a Mastodon. The rind occurred several feet below tlie surface in a peat bog. 



The jaw weighs 54 lbs., and is 30 inchts long by 24 inches wide, by 18 inches high. I't 

 ditiers from the jaws of living animals in its great massiveness — a section through it almost 

 forming a circle. The exterit)r is black in color and of a hard dense structure, being ap])arently 

 tilled with intiltrated iron. 



The jaw contains four teeth — two on either .side — none in front. The row on either side is 

 about three inches wide by ten inches long. The front teeth contain three rows of nipples and 

 the rear four rows. 



A loose tooth was found to weigh one pound and a half. Tlie tteth exhibit a remarkable 

 degree of preservation, as the enamel remains as it was when the animal died. The tops of the 

 nipples are notched by wear, show the hard black dentine beneath. From their appearance the 

 animal would seem to I'e herbivorous. 



The front of the lower jav shows a peculiar structure as though it had contained tusks m 

 teeth during the animal's lifetime. 



(The rinders attempted to reach other parts but have been so far unsuccessful.)

REPORT FROM THE ENTOMOLOGICAL SOCIETY OF ONTARIO TO THE ROYAL 



SOCIETY OF CANADA. 



Through the Rev. C. J. S. Bethunb,. D.C.L., Dhlegate. 



When a society has attained to mature age, like an individual it cannot be expected that 

 its thirty-seventh year should be marked by any great crisis or any striking event. It is natural, 

 therefore, that the representative of the Entomological Society of Ontaiio should be able t^ 

 present to the Royal Society of Canada only a report of quiet work and steady progress sinci,' 

 (>\ir meeting a year ago. 



The thirty-seventh annual meeting was held in November last at London, the headquarters 

 of the Society. The opening proceedings Avere rendered notable by the joint meeting which 

 was held with the lecently organized London Horticultural Society. It was held in the splendid 

 new building of the Normal School and was attended by a large and appreciative audience, 

 representing both the Societies and the general public as well. It was presided over by Prof. 

 C. C. James, Deputy Minister of Agriculture for Ontario, who delivered an address on the value 

 of Horticulture in its various a.spects, its intellectual advantages and its attraction for person.^ 

 of literary tastes. He was followed by Mr. VV. E. Saunders, of London, who read a paper on 

 " The planting, care and pruning of the trees in the parks and streets of the city," which is a 

 matter of much importance in a place whose beauty and attractiveness largely depend upon the 

 noble avenues of trees in the streets, and the parks secured to the public by a wise and rare 

 forethought. Dr. Fletcher, Dominion Entomologist and Botanist, then gave an address, illus- 

 trated with beautiful lantern picturts, and showing how trees should be giown and treated and 

 the admirable results that have been obtained at the Expeiimental Farms at Ottawa and in 

 the North-west. He also took up the subject of insects and described a large number of the 

 most destructive species and the remedies that may be most successfully employed against them.
