TO assure a national supply of dyes, independent of any foreign sources, it is necessary that in respect of each of the three stages of manufacture—(1) raw products, (2) intermediates, (3) finished dyes—his country should be selfrsupporting. An abundant supply of the necessary raw products is available in Great Britain, and, moreover, their manufacture in the state of purity required for the production of dye manufacture has long been carried out within the country on a very extensive scale. In respeot of intermediates, at the outbreak of war we were very badly (placed indeed, for although at one time, otr another various firms in this country had manufactured a considerable number of the necessary intermediate products, in most instances they bad been forced, by continuous, underselling on the part of German firms, to abandon their manufacture. This state of affairs led to the result that the British firms which manufactured colours were to a very large extent dependent upon imported intermediate products. The correctness of the statement that before a really national supply of dye can be established there must be a sufficient, and secure, supply of intermediates will not be denied by anyone who has to deal with the manufacture of colouring matters, for without them the dye-maker is in the position of the dyer who has no supply of colours. Moreover, if the dyewares that are to be produced from them are to be of a kind which will enable our textile industry to compete successfully in the open export market, every dye-maker will admit that the intermediates must be of the finest quality.
