Abundance of grain.
--The Montreal Advertiser learns from Upper Canada that the receipts of wheat from the farmers are greater than ever known before. The storehouses upon the railway lines are filled to repletion, and the amount accumulated at the various ports on navigation already will furnish many week's employment for all the lake and river craft. Farmers show much anxiety to sell at present prices, and large quantities have been disposed of on four or six months credit.
