Words or conduct, communicated properly to the offeror, which show that the offeree intends not to accept the offer amount to a rejection thereof.1 A so-called acceptance which varies materially from the offer, is a rejection thereof in legal effect.2 Knocking down property at an auction to a higher bidder,3 or adjourning the sale with-out accepting a bid,4 is in each case a rejection of the unaccepted bid.
