The present characteristic and beautiful building was then erected, and with the aid of Government, it was furnished with some of the chief instruments; but much to my regret the establishment has been exclusively limited to the purposes of a scientific observatory, without any provision of a popular description for which it was originally intended.

By the level line to Edinburgh the branch to Leith becomes also somewhat more lengthened than by the descending line, which, instead of preserving the level, is always falling, or approaching towards Leith. The reporter, as before noticed, has various modes in view, by which the branch to Leith may be made of a very easy line of draught, or be thrown into a succession of levels, by a species of lockage or stepping. Where sudden acclivities occur on the line of a railway they are generally overcome by an inclined plane, of greater or less extent, according to the particular rise, and on this the loaded wagons are brought up by a steam-engine. But to render railways applicable to all situations, it seems to be necessary that the overcoming of such obstacles should be within the reach or power of the driver and his horse; by working a kind of gin connected with an inclined plane, or by lifting the loaded wagons perpendicularly, which may in various ways be accomplished by the aid of pulleys, by the common lever, or the revolution of a wheel.

100 The proposal stated is not new; it has been often under the memorialist’s consideration, and he has heard it favourably spoken of and received by several of the Professors of the University, in particular Professors Leslie and Playfair, and others eminently qualified to judge correctly upon the subject.”

The writer had all along been considering various schemes—providing the men could be kept under command—which might be put in practice for the general safety, in hopes that the Smeaton might be able to pick up the boats to leeward, when they were obliged to leave the rock. He was, accordingly, about to address the artificers on the perilous nature of their circumstances, and to propose that all hands should unstrip their upper clothing when the higher parts of the rock were laid under water; that the seamen should remove every unnecessary weight and encumbrance from the boats; that a specified number of men should go into each boat, and that the remainder should hang by the gunwales, while the boats were to be rowed gently towards the Smeaton, as the course to the Pharos or floating light lay rather to windward of the rock. But when he attempted to speak, his mouth was so parched that his tongue refused utterance, and he now learned by experience that the saliva is as necessary as the tongue itself for speech. He then turned to one of the pools on the rock and lapped a little water, which produced an immediate relief. But what was his happiness when, on rising from this unpleasant beverage, some one called out ‘A boat! a boat!’ and on looking30 around, at no great distance, a large boat was seen through the haze making towards the rock. This at once enlivened and rejoiced every heart. The timeous visitor proved to be James Spink, the Bell Rock pilot, who had come express from Arbroath with letters. Spink had for some time seen the Smeaton, and had even supposed, from the state of the weather, that all hands were on board of her, till he approached more nearly and observed people upon the rock. Upon this fortunate change of circumstances sixteen of the artificers were sent at two trips in one of the boats, with instructions for Spink to proceed with them to the floating light.5 This being accomplished, the remaining sixteen followed in the two boats belonging to the service of the rock. Every one felt the most perfect happiness at leaving the Bell Rock this morning, though a very hard and even dangerous passage to the floating light still awaited us, as the wind by this time had increased to a pretty hard gale, accompanied with a considerable swell of sea. The boats left the rock about nine, but did not reach the vessel till twelve o’clock noon, after a most disagreeable and fatiguing passage of three hours. Every one was as completely drenched in water as if he had been dragged astern of the boats.”

The cross section (shown in Fig. 12) of the metalled road to be the same in all respects as that already described for the causewayed70 roadway. But the cross section is to rise from the interior brows or slopes of the paved channels to the centre of the roadway, at the rate of 1 in 25. The bottoming of the road is to be of broken stones from the excavated matters of the Calton Hill works; the pieces of stone not to exceed five or six lbs. in weight; to be laid by hand in a compact manner to the depth necessary for preparing the road for the upper strata, viz., a layer or stratum of clean sharp sand four inches in thickness, laid all over the surface, and forming a bed for the upper or road-metal stratum, which is to be seven inches in thickness, and to consist of broken stones taken from the quarries of Salisbury Crags, or the lands of Heriot’s Hospital, as may be finally agreed upon. The road-metal is to be broken into pieces of such dimensions as to pass freely through a screen, to be provided by the Commissioners, the meshes of which shall not exceed one inch and a half square. The whole to be finished with a ‘top-dressing’ of sea-gravel, in such a manner that none of the road-metal shall appear on the surface of the roadway when it is completed.”
