Page 175 - He was convinced that with a correct glass, and a log properly " hove" by an experienced seaman, the distance would be given to one-eighth of a mile. Under all circumstances, he thought the common log was the best known means of ascertaining the speed at sea. " Massey's" log was, perhaps, the best of all the other instruments he had seen and tried. When a vessel was going less than 5 knots, it did not indicate sufficient distance ; between 5 knots and 8 knots it was very correct ; but above that...
Page 403 - Any hollow in the drain intercepts the sedimentary matter which the flow of the drainwater would otherwise carry out with it; the sectional area of the water-way is thereby lessened, and the sediment, gradually accumulating, after a time causes a stoppage, the drain bursts, and the work has to be re-done. The Level placed in the trench, as it is dug preparatory to laying in the tiles, indicates by the plumb-line any irregularity bad workmanship may occasion.
Page 184 - Metallic tanks have since been very generally adopted, with the difference in favor of those now used, that they are of the cheapest metal — iron; but, on the contrary, they have usually the disadvantage of not being shaped to the form of the vessel, and of not contributing in any way to the strength of its structure. Saving of First Cost. It appeared from the report of the master shipwright of Deptford Dockyard, on comparing the quantity of timber employed for the Dart...

The large diameter given to the steam cylinders was purposely with a view to working very expansively, and on the trial recorded the steam, being at 4 Ibs. pressure in the boiler, was throttled on its passage and cut off by the expansion valve at l-6th of the stroke, that is, 1 foot from its commencement.
Page 348 - By the motion of these interior vessels, which are filled with non-conducting substances, the air to be operated upon is moved from one end of the exterior vessel to the other, and as one end is kept at a high temperature, and the other as cold as possible, when the air is brought to the hot end it becomes heated, and has its pressure increased ; and when it is brought to the cold end, its heat and pressure are diminished.
Page 167 - HOSKEN was anxious to record clearly the points where he was satisfied the propeller was preferable to the paddle-wheel for steamers generally, but more particularly for the purposes of war and for Atlantic navigation. By using the screw, a great weight was entirely removed from the top sides and centre of .the ship. The exertion of the power of the engines was transferred from the top sides and centre to the lower midship body, which was the strongest part of the ship. There was a saving of nearly...
