MANUFACTURE OF PAPER.

SUITABLE DOMINION TIMBERS. PROSPECTS FOR STARTING INDUSTRY. By Teleffraph.—Press Association. Wellington, Last Night. Tests to decide the suitability of New Zealand timbers ae paper-making materials have 'been carried out by the Imperial Institute, London. Discussing the report just received, the Director of the Forest Service says the re- I suits show that four species of birch I yielded pulps of a similar character, which bleached readily and furnished fairly strong papers of good quality. The yields of pulp were fairly good—--41.5 to 44 per cent. —that from red birch, or fagus fusca, being the best. Tawa wood also gave a fairly good yield of pulp (42.5 per cent.) and yielded paper of a similar quality to that obtained from the species of fagus. Kamahi wood gave a rather low yield of pulp (36.5 per cent.), which, however, bleached satisfactorily and had igoodj felting properties. The strongest papers were obtained from pinus laricio and pinus radiata, 'bul? the pulps from these did not bleach quite so readily as from the other six samples; the yield of pulp (39 per cent.) was only moder-* ately good, and, owing to the presence of knots in the wood, a larger uJmount of causftc soda was required. The director adds that all these timbers may be regarded as suitable for the manufacture of paper pulp in New Zealand if available in sufficient quantities, but before tho manufacture of pulp is undertaken on a commereia) scale a number of factors will need careful consideration. The questions involved will be investigated in detail by the forest service, and a report on commercial aspects of paper-making will be furnished on completion.
