receipt, and deeds of release. Taxes on contracts are not always levied by means of stamps. The duty on sales by auction, abrogated by Sir Robert Peel, was an instance in point. The taxes on transfers of landed property, in France, are another: in England there are stamp-duties. In some countries, contracts of many kinds are not valid unless registered, and their registration is made an occasion for a tax.
Of taxes on contracts, the most important are those on the transfer of property; chiefly on purchases and sales. Taxes on the sale of consumable commodities are simply taxes on those commodities. If they affect only some particular commodities, they raise the prices of those commodities, and are paid by the consumer. If the attempt were made to tax all purchases and sales, which, however absurd, was for centuries the law of Spain, the tax, if it could be enforced, would be equivalent to a tax on all commodities, and would not affect prices: if levied from the sellers, it would be a tax on profits, if from the buyers, a tax on consumption; and neither class could throw the burthen upon the other. If confined to some one mode of sale, as for example by auction, it discourages recourse to that mode, and if of any material amount, prevents it from being adopted at all, unless in a ease of emergency; in which case as the seller is under a necessity to sell, but the buyer under no necessity to buy, the tax falls on the seller; and this was the strongest of the objections to the auction duty: it almost always fell on a necessitous person, and in the crisis of his necessities.
Taxes on the purchase and sale of land are, in most countries, liable to the same objection. Landed property in old countries is seldom parted with, except from reduced circumstances, or some urgent need: the seller, therefore, must take what he can get, while the buyer, whose object is an investment, makes his calculations on the interest which ho can obtain for his money in other ways, and will not buy if he is
