Bonedust.

It seems almost inconceivable that last year 3,518 tons of bonedust, valued at £23,057, should have been imported into the colony for manure, when the unmanufactured product exists here already in such great quantities. The establishment of bonedust mills in all the districts of the colony, on the same principle that boiling-down establishments dot the country, would not involve any great outlay of capital, and would lead to greater care and economy in the collection and storage of bones, and to a good deal of labour being employed. It would be necessary, however, to impose a moderate import duty, and to offer a Government bonus for the production of the first five hundred or one thousand tons. The demand for bonedust increased last year, judging from the imports, by 30 per cent., and the increase is likely to continue.
