The special committee appointed at the conferenoo of the grain shippers of ii vltimore, Philadelphia, and New York have (according to a Home paper of Januiry 2nd) agreed upon a form of contraot to govern dealers in cereals between tho United States and Europe. Thi« w tho drab American contraot ever formulated, and it has become neces sary, it is alleged, beoause of the objection to many of the conditions of the contract formulated by the London Com Trade Association, whioh were cousidered unjust to American shipperi. It will bo submitted to tho shippers at Baltimore and Philapol phia for their approval, and will then be forwarded to Londoi for aotion by the English, shippers and dealers of grain.

Tbe fact that a shipment arrives out of condition shall not be by itielf sufficient proof of lm- Kroner shipmeut. Should tho " lay daya " c loss than as stipulated, tho demurrage to complete them shall bo allowed by the seller iv cash from the invoice, but the seller shall have the right to buy from owner or captain any days to complete the required number, providing it be done before the documents are taken up. In default of the fulfilment uf contraot, either p»rty to the transaction shall have the right of repurchase or resale, the defaulter to make good on demand the loss, if any, by suoh repurchase or resale, which right must be used within three busi ness days following the knowledge of the default. Claims on acoount of quality or condition must be made within two business days following tho (inal discharge of the shipment. All disputes arising out of the contraot, as to quality or condition of ship ments, from ports or plaoes where organised associations of graiu dealers exist, shall be deoidod by the official committee of the association appointed for that purpose.
