NGAKAWHAU COAL.
Mr Chambers, manager of the Ngakawhau coal mine, has received a letter, of which the following is a copy, referring to another test of the Ngakawhau coals:— " Wellington, Feb. 22, 1873. '•' Chas. Hartman, Esq., " Sib, —According to your instructions I have tested the forty bags of coal sent on board at Nelson. I found that three tons of these lasted as long as three and a half of New South Wales coals; this was under easy steam. On putting the engines to full speed I found I could not carry within three pounds of the pressure of steam I could have carried with N.S.W. coals under similar circumstances, but with slightly less consumption of the New Zealand coal, lam of opinion that we could have carried better steam if the firemen had sufficient experience in working the coals. " They are a very strong coal, and I should think would be very severe on the fire bars. They make very little ashes or clinker, and the least smoke of any coals I have ever used. " I remain, Sir, " Tour obedient servant, " John Lees, '' Engineer s.s. Wellington."
