The grub, living under ground in the daytime, and sallying forth at night, is a ferocious enemy to cabbage-plants, lettuce, and most of the young, tender vegetables; but, by taking a lantern and a pan after dark, the gentlemen can be collected whilst on their tour, and poultry are very fond of them. Last year, the potato crop failed throughout Canada. What a singular dispensation!--for it alike suffered in Europe, and no doubt the malady was atmospheric. The hay crop, too, suffered severely; but still, by a merciful Providence, the wheat and corn harvest was ample, and gathered in a month before the customary time. By the word corn I mean oats, rye, and barley; but in the Canadas and in the United States that word means maize or Indian-corn only, which in Canada, last summer, was not, I should think, even an average crop. It is extensively used here for food, as well as buckwheat, and for feeding poultry. But to our journey westward. I arrived at Toronto on the 27th of June, and found the weather had changed to variable and fine. On steaming up the harbour, I was greatly surprised and very much pleased to see such an alteration as Toronto has undergone for the better since 1837. Then, although a flourishing village, be-citied, to be sure, it was not one third of its present size. Now it is a city in earnest, with upwards of twenty thousand inhabitants--gas-lit, with good plank side-walks and macadamized streets, and with vast sewers, and fine houses, of brick or stone. The main street, King Street, is two miles and more in length, and would not do shame to any town, and has a much more English look than most Canadian places have. Toronto is still the seat of the Courts of Law for Western Canada, of the University of King's College, of the Bishopric of Toronto, and of the Indian Office. Kingston has retained the militia head-quarter office, and the Principal Emigrant Agency, with the Naval and Military grand depots; so that the removal of the seat of Government to Montreal has done no injury to Toronto, and will do very little to Kingston: in fact, I believe firmly that, instead of being injurious, it will be very beneficial. The presence of Government at Kingston gave an unnatural stimulus to speculation among a population very far from wealthy; and buildings of the most frail construction were run up in hundreds, for the sake of the rent which they yielded temporarily.
