In fact, although 12th December 1972 passed without any survey plan having been prepared and, consequently, without either party being in a position to express satisfaction or otherwise concerning it, the vendor did not then treat the contract as at an end. The contract required the purchaser to pay a further deposit of $2,950 on 12th December 1972 but it failed to do so, whereupon the estate agent engaged in the transaction, acting on behalf of the vendor, on 4th January 1973 communicated by telephone with the purchaser's solicitors and on the following date received from them a cheque for the sum of $2,950 which, in accordance with condition 1 (a), he deposited in his trust account and for which he issued an appropriate receipt dated 6th January. He at the same time informed the vendor's wife by telephone of the receipt of the further deposit. Then, on 23rd January 1973, the purchaser's solicitors, in a letter which referred to an earlier letter from the vendor's solicitors dated 6th December in which a copy of "the proposal plan" referred to in condition 1 (d) had been requested, enclosed a photo-copy of a plan which was not a survey plan although the letter appears to treat it as answering the requirements of condition 1 (d). Thereafter nothing more appears to have happened until about the end of April 1973 when surveyors engaged by the purchaser sought entry upon the vendor's land to carry out the necessary survey and were refused entry by the vendor. There then ensued, on 2nd May 1973, a telephone conversation between the managing director of the purchaser and the vendor in which the former sought to arrange a time convenient to the vendor at which the surveyors might enter the land. The result of this telephone conversation was inconclusive and the next day the purchaser's managing director called on the vendor and was told that the latter had received legal advice that the surveyors were to be refused entry to the property. Then the purchaser received from the vendor's solicitors a letter on 7th May offering to refund all moneys paid and stating that no binding contract existed between the parties and that, presumably in the alternative, the vendor was entitled to cancel the agreement pursuant to condition 1 (d) and elected to do so.
