56 THE EEPOHT OF THE i\o. 36 



In the course of the season the pool was visited by representatives of the five 

 species undermentioned : — 



BasicBschna Janata, Say. 



Libellula quadrimaculata, Linneus. 



Libellula pulcJiella, Drury. 



Plaihemis trimaculata^ De Geer. 



ZSshna umhrosa, E. M. Walker. 



The last named was a particularly brilliant object. It was seemingly set with 

 jewels. It flashed in the sunshine with the glories of emerald, sapphire, and topaz. 

 It hovered over the pool, as a kestrel hovers over an English meadow. 



The whole scene in the bright autumn days was very lovely. The Golden Eod 

 grew thickly around, its colors relieved by the blue of the Michaelmas Daisy. Here 

 and there a clump of the Glaucous Willow gave an air of seclusion to the spot; 

 and a few yards away the stately forest trees ascended, with foliage already tinged 

 with russet, crimson, and gold. 



It was a spot in which the contemplative man might hold communion with 

 his Maker, and muse upon all His works, and "rejoice in giving praise for the 

 operations of His hands." 



On October 17th — the day being bright and warm — I visited the pool again, 

 but could detect no living thing within it. All its frequenters had lived out their 

 lives, or sought their winter retreats. 



The ground was covered with dead leaves, brown and sear ; and silence reigned 

 — "Sic transit gloria mundi.'' 



THE BEAN MAGGOT IN ONTAKIO IN 1910.

It was the writer's privilege and pleasure to attend the inaugural iih'cnn.; ol 

 the Bean Growers' Association of Kent County, at Eidgetown, in May. At this 

 meeting the fungus diseases and insects injuring beans were discussed at some 

 length. During the discussion many of the growers asked about a little white 

 "weevil" which they claimed was their worst insect pest. Most of them had the 

 idea that it was the bean weevil, but, from the descriptions given of it, the writer 

 came to the conclusion that the pest was not the bean weevil. It was, however, im- 

 possible to say what the insect was from the accounts given by the growers at the 

 meeting. An arrangement was, therefore, made for the Biological Department 

 of the Ontario Agricultural College to investigate the insect and fungus diseases of 

 beans which might become prevalent in Kent County during the summer of 1910. 



About the 10th of June word was received at the College that "the little 

 white weevil" was doing serious harm in Kent County. Many -fields of beans had 

 failed to germinate properly owing to the ravages of the pest. On June 21st the 

 writer went down to Eidgetown, in Kent County, to investigate as fully as pos- 

 sible the cause of the trouble. At Eidgetown Mr. W. E. Galbraith, President of 

 the Bean Growers' Association, met the writer and a start for a trip of inspec- 

 tion was made. The farm of Mr. Galbraith was first visited. On looking over the 

 bean fields, here and there in the rows were seen plants which were little more 

 than blackened stubs. The plumule and cotyledons had come above the ground, 

 then withered and discolored. When some of these stubs were examined the coty-
