To-night's Telegraph says : It will be within the recollection of lomo of our readers that some two or throe years ago Mr J. S. M. Jaoobson announced that he had discovorod n fiold in Canterbury whore crystals, which ho believed to be diamonds, wore plentiful. He has now brought tho matter beforo tho Industrial Association, by urging that body to re quest the Government to offer a bonus for tho discovery of suoh a field. Tho Association, though by no means satisfied that tho specimens hold by Mr Jacobson Are diamonds, to some extent concur with his proposal. Several of tho mem bers hftvo a large experience of tho colony, and think it quito possible that diamonds may bo found, if not in 0 intorbury, in other places, and a committee has been appointed to confer with Mr Jacobsen on the subject. Mr Reeso stated at last night's meeting that a man with whom ho was acquainted found a largo orystal in a claim on tho West Ooasfc some y«ars ago. Whether it was a diamond or not Mr Reese could not s^iy, but tho man who found it prized it so highly that ho Bent it homo, and had it cut and mounted in gold. Mr Jacobson has, it appoars, been very unfortunate in hi* en deavors to havo these crystals teoiod. Shortly aftor ho found tho fiold ho sent some specimens home to a firm of experts for their opinion, but tho only roply that ho got was a request that he would send somo more. This hardly suitod Mr Jacobson's jdoas, and ho waited until a friend was going homo, and sent his best and largest specimen with him. That was two years ago, and ho has hoard nothing of it sinco. Mr Jacobson declare* that ho will not disoovor tho locale of the field until a bonus is offered by Govern ment. His reason in that part of tho field ia on private property, and part in tho hands of tho Government, and of course without a special permit ho could work neither. Ho showed somo of his speci mens to Mr Kollar of the Royal Illusionists and that gentleman, who is an old dia mond digger, said that they wore undoubt edly diamonds, but soft.
