Tliis is a most stupendous work and could not have been eifected without iron tools.

In this country may be found growing wild, and in great plenty, hops, grapes, cranberries, plums, strawberries, gooseberries, blackberries, raspberries, currants, plantain, dock, yarrow, spikenard, sarsaparilla, mullen, burdock, dock, English pursley, French sorrel, peppermint, common mint, catnip, thorn apples, of whicli pies are made, Indian corn, potatoes, oats and flax -- peas, beans, and all kinds of productions grow very rank. Wheat this year was hurt with the rust, but grew amazing rank. Face of the country beautiful -- no stones of any consequence. From 3 pints of barley 3 bushels were produced this year. There appears by the best accounts to be forts built in the manner of those on Sandy creek; all over the country from the St. Lawrence to tlie Black River, and South and Southwest, all round the lake particularly, and upon tlie military grounds -- and these by account correspond with those on the Oliio, in their conformation. They are a ditcli, and the earth is banked up on the inside. The ditches of those which I have seen, I think must have been at first about 8, 10 & 12 feet wide ; how deep cannot be even judged with any degree of certainty, until some person who has time shall dig down and tlirow out the made earth. By whom were those works wrouglit 1 Not by the natives, surely ; because in various parts of tliis county iron implements are dug and ploughed up. And if the natives ever had the art of working iron, it is not probable they would lose an art so useful. Further, nothing ever appeared in the natives which indicated so much improvement in the art of self defence, as to build forts so regular as those are found to be.
