5. As far as the 232 pounds 10s. 0d. was concerned, it is obvious that by the mortgages in question the bankrupt gave the appellant a preference or advantage over the other creditors, for he thereby converted an unsecured debt into one secured upon Fallon's equity of redemption in his interest as a joint tenant in the subject lands. But as regards the balance of the mortgage moneys the position was different. The appellant offered uncontradicted evidence, which Townley J. accepted, to the effect that the mortgages were given in pursuance of a stipulation made by the appellant as a condition of his granting the loan and giving credit for the price of the ninety-five cows. The transaction came about in the following circumstances. The appellant was at one time a butcher at Biggenden, but about 1954 he sold his business and became a cattle dealer. Fallon was an auctioneer and commission agent in the same town. On some occasions the appellant bought cattle from Fallon, and on others he sold cattle to him. It was through Fallon that he sold his butcher's business. He had to wait at times for money which Fallon owed him, and on a couple of occasions cheques which Fallon gave him were dishonoured; but the cheques were eventually met, and until June 1957 the appellant received full payment sooner or later in respect of every transaction. About the 29th June, however, the 232 pounds 10s. 0d. for cattle bought by Fallon at the beginning of the month being still unpaid, Fallon approached the appellant with a request for a loan. There followed a conversation, as to the precise terms of which the evidence is not entirely clear. Fallon, who gave evidence by affidavit and was not cross-examined, said only that the amount which he asked the appellant to lend him was 2,000 pounds, and that the appellant gave him 500 pounds and asked him to accept certain cattle for the sum of 1,900 pounds, the cattle being ninety-five cows at a price fixed by the appellant at 20 pounds per head. The appellant's account of the matter is found only in the depositions of his examination under s. 80, these having been put in evidence before Townley J. by the respondent. The appellant denied that Fallon's request was for a loan of 2,000 pounds. According to him Fallon said that he was short of money but that he wanted to buy the ninety-five cows, that he had some cattle (about two hundred and fifty) which he was expecting to sell and that if the appellant would sell him the ninety-five cows and lend him 500 pounds in cash he would pay him as soon as he sold the other cattle. The appellant's reply, according to one account that he gave, was: "Keith, it's a big order but if you can give me some sort of security on the thing". Another version was: "Keith, you'll have to do something about it. I can't see you stuck. Can you give me some security?". He said that Fallon replied that he would give him a second mortgage on "the farms" an expression evidently referring to the lands the subject of the mortgages. In addition, he said that Fallon "suggested he would give me 50 pounds for the loan"; and the sense of his evidence is that that was agreed upon. There is, however, nothing in the evidence to warrant a finding that the agreement for security extended to the antecedent amount of 232 pounds 10s. 0d. The sale of the ninety-five cows and the loan of the 500 pounds were both made on 29th June, Fallon assuring the appellant that as soon as he sold his other cattle he would be able to pay in full. On 1st July the appellant wrote out for his own purposes particulars of Fallon's indebtedness to him. These included an item "Loaned 550 pounds". This he explained in his examination in the bankruptcy, as referring to the 500 pounds which he had lent and the additional 50 pounds "for the loan". His evidence was very vague as to whether a specific date for payment was agreed upon. An invoice of Fallon's dated the 29th June, however, contained, over Fallon's signature, the entries:
