Wanganui sailed last night for the Bluff. The p.s. Samson arrived from Oamaru and passed up to Dunedin. - A topsail schooner, supposed to be the WanS,nui, arrived this morning and passed up to unedin. The ship Undine not having enough ballast on board to be removed into the dock, the brig Craigellachie was taken in yesterday afternoon. The three-masted schooner Euphrosyne, which arrived at the Heads yesterday morning, sailed up in the afternoon. She left the Bluff on Saturday morning with strong N.E. winds until off the Taieri, when the wind fell to a calm; a light breeze springing up enabled her to reach the Heads. She brings 45,000 ft of timber. Captain Thomson, harbor-master at the Bluff, is undoubtedly an inventive genius. Not long since we noticed his patent ancnor; how we have to chronicle that he has successfully constructed a'machine for registering the rise and fall of the tides. Reporting to the Secretary for Works, he says“l received a book from you a abort time age to keep a register of the tides in, but I could not see my way to keeping such a register as, would be of any practical value, without serious inconvenience, as it would require constant attention both day and night. I therefore set about inventing a self-registering machine, which would record’ all phenomena connected with tides, and 1 have succeeded in doing so. It will register for a week at a time the limits of high and low water, and the time they take place, and any irregularities caused by storm or earthquake waves, showing the height to which they rise, and the time they take place. It will also record the time that elapses during the rise and fall of each foot. When I completed my invenwas hot aware that anything of the kind was in use, but I have since been told that a machine which registers for one day is in use in Newcastle, New South Wales, but on quite a different principle; and 1 cannot learn that it docs any more than show the limit of each tide, and the time. This, however, I easily arrived at, but that would not suit my purpose, Us my other duties would frequently cause my absence at the time the machine required re-setting, and here: my difficulties commenced. I have, however, succeeded in overcoming them in the most satisfactory way. The machine has been made by myself, but X require an ordinary eight-day spring clock, with slight alterations made to suit my arrangements, and a* small wooden box on the wharf for its safe keeping..
