The first rule about the construction of documents enjoins that the simple natural meaning of words be ascribed to them unless this is impossible, and the defendant is severely precluded from giving oral evidence to disparage the clear expressions already reduced by her or for her into writing. We have come to the conclusion in this respect also that the learned trial judge had not given the document exhibit 1 its natural and ordinary meaning and that on a close reading and study of that document it is manifest that the defendant states in exhibit 1 that the amount of 600 was the purchase price of the land which she had contracted to sell to the plaintiff.
