The parties have inserted each provision in the contract, and accordingly, if possible, a contract should be so construed as to give effect to each provision inserted therein.1 Thus a clause in a building contract providing that no lien should be taken thereunder is not repugnant to a subsequent provision requiring the contractor to show by sufficient evidence that the premises are free of liens.2 Whether in this sense a printed heading is a part of the contract written thereunder is a question on which there seems to be some conflict. It has been held that a printed heading on an order blank may be looked to to show that the order was taken as a publisher and not as an engraver;3 while a notice on a letter head that all orders were subject to delays arising from strikes was held not a part of a contract written thereunder,4 and terms printed at the head of a bill cannot be considered as a waiver of express provisions of the written contract for the sale of such goods, which contract is contained in a letter mailed on the same day as that on which the goods are shipped.5 The rule that every part of the contract must be given effect applies to a contract that is partly written and partly oral.6
