On 12th August 1930 the Adelaide Steamship Co. Ltd., on Turner's order, had delivered to the bank the certificates for the 417 shares which were in his name. These 417 shares were retransferred to Miss Rogers, she signing the transfers as transferee. The transfers were registered on 25th August 1930, and the certificates returned to the bank. On the same day the above-mentioned letter signed by Miss Rogers was delivered to the bank, presumably by Gardiner. Miss Rogers in evidence stated she had no recollection of the document or of the signing of the scrip.
On 5th December 1930 Miss Rogers at Gardiner's request executed a general power of appointment over her interest in her father's will and out of the proceeds, in January 1931, made a gift to Gardiner of £225. The balance of the proceeds, £165 14s., she paid into her savings bank account.
The bank continued to press Gardiner to reduce his overdraft, and in January 1932 Gardiner promised the manager to bring in Miss Rogers to see him. On 3rd February 1932 Miss Rogers, accompanied by Gardiner, went to the bank and saw Sheridan. In her evidence Miss Rogers said that Gardiner had stated to her that "Mr. Sheridan wanted to see me at the bank about my Adelaide Steamship shares, that he wanted me to sign a paper, I thought he meant the 200 shares he had borrowed from me, I did not ask him why Mr. Sheridan wanted the paper signed and he did not tell me why." Sheridan read to her an equitable mortgage of the shares lodged with the bank. It was a long document, which, Miss Rogers said, Sheridan read deliberately and slowly but she did not under- stand its meaning. She signed the document and also signed a letter in the following terms :- Adelaide, 3rd February 1932. The Manager, Bank of New South Wales, Adelaide, S.A. Dear Sir,
I hand you herewith equitable mortgage executed by me this day to secure certain advances and accommodation afforded and to be afforded by you to Charles Lennox Gardiner of Semaphore, S.A., retired civil engineer, against the security, inter alia, of shares already lodged by me with your bank as particularly described at foot hereof.
I am aware that the account of C. L. Gardiner with your bank is at this date overdrawn £6,772 17s. 6d. exclusive of interest. Yours faithfully, May E. A. Rogers. 987 £1 f.p. Adelaide Steamship Co. Ltd. as comprised in scrip certificates Nos. 13248, 13479, 13480, 13481, 13482, 13483. May E. A. Rogers."
In evidence Miss Rogers stated that she read the letter at the time of its signature but she did not remember the footnote above her second signature. She also deposed in cross-examination that she remembered that she had signed the equitable mortgage and
