A very successful trial of Mr Ford's siren took place on the 16th. It was flvst tested at the Railway Wharf, then at Soamos' Island, and finally at Fort Ballance. During- the , trial at Soamos' Island half a gale was blowing in the direction of Potone, yet the siren was heard distinctly at Fort Ballance. The cylinder used was made of copper instead of' brass, which is a more suitable material, whilst the piston was without packing. Still very good results were obtained. This was all the more satisfactory as tho instrument w;is only 2-1 inches in diameter, tho proper sizo being from six to eight inches. It is intended to have a brass cylinder of the requisite size constructed at the Petono workshops, when another trial will bo ma do. Messrs J. and A. Anderson, of Christchurch, are tho success!ul tenderers tor the erection of.a lighthouse tower on Farowbll Spit. Thp, contract prico is d08(a) 10a.
