It was in great part the existence of this anomaly which led to the re-establishment of the sample post in 1887. No exact estimate was made of the cost of dealing with sample packets, but the authorities stated that the rates proposed, viz. under 4 ounces 1d., over 4 ounces and under 6 ounces 1-1/2d., and over 6 ounces and under 8 ounces 2d. (8 ounces to be the maximum weight), would be remunerative, and that any immediate loss to revenue in consequence of the reduction in rates would therefore be likely soon to be made up. This statement must, however, have been based on general considerations and estimates. In the following year the Secretary to the Post Office (Sir Arthur Blackwood) told a Select Committee of the House of Commons that the Post Office had not any return of the cost per million letters, or any return of that kind by quantity, and that the Post Office could not give the actual cost per million letters.[505] The post, which was re-established in the interests of trade and could only be used by traders, was continued until 1897, when the Jubilee reductions brought down the postage on ordinary letters to the level of the sample rate. The sample post was never more than a very minor part of the Post Office business. In 1865, when the total number of letters passing by post was some 700 millions, the number of samples was one million. In 1870 the number of samples was four millions. In 1896, the last year of its existence as a special rate, the number of samples was nine millions. In that year the number of letters, etc., was some 3,000 millions. As a result of the increase of letter postage on the heavier letters, as a war measure, it has been deemed necessary to re-establish the inland sample post. On the 1st November 1915 the post was accordingly re-established substantially as it existed prior to 1897. The rates of postage are the same, and the regulations practically unaltered. * * * * * FRANCE
