specified design and complete it before Ist March 1927, to lay on
water, and to supply some fencing posts. Further, by another
agreement of the same date, the vendor agreed that for the next
wheat season, that of 1927-1928, the purchaser should cultivate 700
acres of the land as a share-farmer, and should be entitled to fallow
the land which was under crop in 1926, the fallowing being "for
his use after taking possession on the Ist day of March 1928 of the
said block as purchaser thereof under an agreement for sale and
purchase entered into simultaneously herewith by the parties
hereto." Up to Ist March 1928 the parties substantially performed
the provisions of these agreements. But the vendor was not then
in a position to complete the contract, because his land was encum-
bered with greater liabilities than the contract provided for. The
purchaser, who had in fact used and occupied the land for the purpose
of his share-farming agreement, remained in possession, and sowed
1,400 acres of wheat for the ensuing season. The vendor's solicitors
made some efforts to rearrange the encumbrances, which included
other land as well as the land sold, so that the sale might be completed
according to the terms of the contract. The purchaser's solicitors,
after some complaints of the delay and a request for an assurance
that the sale would be completed, at length on 13th October 1928
served on the vendor a notice fixing 5th November 1928 as the
date for settlement, and notifying him that if he failed to complete
the sale upon that day, the purchaser would treat the contract as
at an end and act accordingly. At this time the vendor's attempts
to rearrange the encumbrances upon his various lands so as to enable
him to complete the contract were proving successful, but when the
residue of the purchase-money payable in cash was tendered to him
by the purchaser's solicitors on 5th November 1928 he was not in a
position to carry out his contract. The vendor's solicitors, however,
asked the purchaser's solicitors whether the purchaser would sign
some application forms for the purposes of taking over the mortgage
liabilities contemplated by the contract in a way which, although
convenient, he was not strictly required to follow. His solicitors
did not at once determine the contract but agreed to consult the
purchaser, and after failure to comply with the notice no election
