Trois Rivieres contains about two hundred and fifty or three hundred houses, and ranks as the third town, in point of size, in the provinces. It is one of the oldest settlements in the country, and its founder, it is said, calculated upon its becoming in a short time a city of great extent. It has hitherto, however, increased but very slowly in size, and there is no reason to imagine that it will increase more rapidly in future, at least until the country bordering upon the St. Maurice becomes settled, a period that may be very distant. The bank of iron ore in the neighbourhood, by the manufacture of which it was expected that the town would suddenly become opulent, is now nearly exhausted; nor do we find that this bank has ever furnished more ore than was sufficient to keep one small forge and one small foundry employed at intervals. The fur trade also, from which so much benefit was expected, is now almost wholly centered at Quebec and Montreal; it is merely the small quantity of furs brought down the St. Maurice, and some of the northern rivers that fall into the St. Lawrence, nearer to the town of Trois Rivieres than to Quebec or Montreal, that is shipped there. These furs are laden on board the Montreal ships, which stop opposite to the town as they go down the river. The country in the vicinity of Trois Rivieres has been represented by some French travellers as wonderfully fertile, and as one of the most agreeable parts of Canada; but it is totally the reverse. It is a level barren tract, and so sandy, that in walking along many of the streets of the town, and the roads in the neighbourhood, you sink into the sand at every step above the ankles. The sand is of a whitish colour, and very loose. The air also swarms with musquitoes, a certain proof of the low damp situation of the place. In none of the other inhabited parts of Canada, except in the neighbourhood of Lake St. Charles, were we ever annoyed with these troublesome insects. In Quebec, indeed, and Montreal, they are scarcely ever seen. The streets in Trois Rivieres are narrow, and the houses in general small and indifferent; many of them are built of wood. There are two churches in the town, the one an English episcopalian, the other a large Roman catholic parish church, formerly served by the Recollets, or Franciscan friars, but the order is now extinct in Trois Rivieres. The old monastery of the order, a large stone building, at present lies quite deserted; and many of the houses in the neighbourhood being also uninhabited, that part of the town wherein it is situated has a very dull gloomy aspect. The college or monastery of the Jesuits, also a large old building of stone in the same neighbourhood, has been converted into a gaol. [Sidenote: ST. URSULE.]
