tendered in evidence, but what was proved was that a course of dealing was adopted which, with minor variations in individual cases, was followed throughout. The Irish suppliers from time to time made known to the plaintiff-either of their own motion or in response to an inquiry from the plaintiff-the quantities of casings which they had available for export to Australia. The plaintiff then offered these quantities to purchasers in Australia. There was never any difficulty in disposing of them.
The first dealing between the plaintiff and the defendant in Irish hog casings was in November 1950. The plaintiff, having ascer- tained that certain quantities were available in Ireland, offered a quantity to the defendant, which the defendant said that it would take. The plaintiff then, after obtaining a licence to import the goods, sent to the Irish supplier an order for this quantity. The order was in the following terms :-
13 November 1950 Messrs. Dillon &Sons, Balleymacthomas, Cork, Ireland.
ORDER No. 1 1000 (one thousand) bundles of HOG CASINGS-unselected
