Corn Exchange, Monday, Sept. 11.—The weather continued most beautiful here until yesterday, when we had some heavy thunder showers, and to-day is gloomy, damp and close. The wind, what little there is of it, is north. The arrivals during last week were moderate except of Foreign Wheat and Barley, of which of course there is yet some quantity to arrive. The new English Wheat coming soft in hand, is slow sale at 1s. to 2s. reduction—free Foreign finds buyers for mixing at last week's currency. Barley is dull sale at last week's rates. Oats are 6d. to 1s. lower. Some new Irish have appeared of fine quality. There is no change in Beans and Peas. Flour is the same as last week.

Corn Exchange, Friday, Sept. 15.—The weather threatened to be stormy yesterday, the barometer fell, and we had some heavy drops of rain, but it has since cleared up, and to-day is 10 degrees warmer and beautifully clear, with the wind south east. In Ireland and Scotland there was a good deal of rain on Sunday and Monday, which (we understand) stopped the harvest work for the time, but we hope by this time they have it fine again. The new English Wheat comes to hand softer and lighter than at first; as usual after being stacked, the yield is much complained of, besides that many of the stacks got so soaked by the heavy rains of the 21st and 23rd of August, that the condition of the Wheat is sadly spoiled. The arrivals are moderate this week, except of Irish Oats, several small parcels of which are of the new crop; there is also a small parcel of new Scotch Barley in fine condition, and new Scotch Oats, also good. Almost all the Wheat has been entered at the 14s. duty; we believe it is over 300,000 qrs. New English Wheat is dull sale: Foreign, on the other hand, is more inquired for, and not to be purchased in any quantity except at 1s. advance. Barley is saleable in retail at Monday's prices. Oats are again 6d. cheaper than on Monday, except for very fine samples. The averages lead us to suppose that on the 21st instant the duty on Foreign Wheat will rise to 16s. per qr.; on Barley it will remain 6s.; on Oats 6s.; on Rye it will rise to 9s. 6d.; on Beans it will remain 10s. 6d.; and on Peas, 9s. 6d.

SMITHFIELD MARKET.

Monday.—There was a considerable and beneficial improvement in trade to-day for everything, but not, however, permanent; at least, the causes which produced the change this morning would not authorise a different conclusion, and the salesmen of the market, although looking forward to a very fair state of things next Monday, do not anticipate that the improvement will last the next succeeding Monday. It appears that London is clear of meat, the which, with small supplies of everything to-day, is the sole immediate cause of the improvement, for, notwithstanding that the market was well attended by both town and country butchers and stock-takers, they, nevertheless, at the opening of the market, appeared disposed to purchase briskly, on the supposition, according to the returns of over-night, that the supplies were large, but when this statement was discovered to be erroneous they then bought freely, and higher prices were more readily given.

Friday.—In consequence of the supply of beasts on sale being large for the time of year, we have to report a very heavy demand for beef, and in some instances the quotations declined 2d. per 8 lbs. From Scotland nearly 200 lots were received fresh up. Prime old downs maintained their previous value; but that of all other kinds of sheep had a downward tendency. In lambs very little was doing, at barely Monday's quotations. Calves moved off heavily, at a reduction of 2d. per 8 lbs. The pork trade was unusually dull, at previous currencies. Milch cows sold slowly at from 16l. to 20l. each.
