changed, as we supposed them to be, in the ratio of 17 yards of linen for 10 yards of cloth.
"But our suppositions might have been different. Suppose that, at the assumed rate of interchange, England has been disposed to consume no greater quantity of linen than 800 times 17 yards: it is evident that, at the rate supposed, this would not have sufficed to pay for the 1000 times 10 yards of cloth which we have supposed Germany to require at the assumed value. Germany would be able to procure no more than 800 times 10 yards at that price. To procure the remaining 200, which she would have no means of doing but by bidding higher for them, she would offer more than 17 yards of linen in exchange for 10 yards of cloth: let us suppose her to offer 18. At this price, perhaps, England would be inclined to purchase a greater quantity of linen. She would consume, possibly, at that price, 900 times 18 yards. On the other hand, cloth having risen in price, the demand of Germany for it would probably have diminished. If, instead of 1000 times 10 yards, she is now contented with 900 times 10 yards, these will exactly pay for the 900 times 18 yards of linen which England is willing to take at the altered price: the demand on each side will again exactly suffice to take off the corresponding supply; and 10 yards for 18 will be the rate at which, in both countries, cloth will exchange for linen.
"The converse of all this would have happened, if, instead of 800 times 17 yards, we had supposed that England, at the rate of 10 for 17, would have taken 1200 times 17 yards of linen. In this case, it is England whose demand is not fully supplied; it is England who, by bidding for more linen, will alter the rate of interchange to her own disadvantage; and 10 yards of cloth will fall, in both countries, below the value of 17 yards of linen. By this fall of cloth, or what is the same thing, this rise of linen, the demand of Germany for cloth will increase, and the demand of England for linen will diminish, till the rate of interchange has so adjusted itself that
