This return afforded us at least the opportunity of comparing the longitude of Yarmouth church, as shown by our chronometers, with its position as laid down by the Ordnance Trigonometrical Survey; and it was satisfactory to find, from the small difference in their results, that the chronometers had not experienced any alteration in their rates in consequence of their being changed from a horizontal position in a room to that of being carried in the pocket.

An untoward circumstance while at this anchorage cast a damp on our party at this early period of the voyage.  Emboldened by the decided appearance of the North-West sky, several of our officers and passengers ventured on shore for a few hours; but we had not been long in the town before the wind changed suddenly to South-East, which caused instant motion in the large fleet collected at this anchorage.  The commander of our ship intimated his intention of proceeding to sea by firing guns; and the passengers hastened to embark.  Mr. Back however had unfortunately gone upon some business to a house two or three miles distant from Yarmouth along the line of the coast; from whence he expected to be able to observe the first symptoms of moving which the vessels might make.  By some accident however he did not make his appearance before the captain was obliged to make sail that he might get the ships through the intricate passage of the Cockle Gat before it was dark.  Fortunately, through the kindness of Lieutenant Hewit of the Protector, I was enabled to convey a note to our missing companion, desiring him to proceed immediately by the coach to the Pentland Firth, and from thence across the passage to Stromness, which appeared to be the only way of proceeding by which he could rejoin the party.

Transactions at Stromness.

June 3.

The wind continuing favourable after leaving Yarmouth, about nine this morning we passed the rugged and bold projecting rock termed Johnny Groat’s house and soon afterwards Duncansby Head, and then entered the Pentland Firth.  A pilot came from the main shore of Scotland and steered the ship in safety between the different islands to the outer anchorage at Stromness, though the atmosphere was too dense for distinguishing any of the objects on the land.  Almost immediately after the ship had anchored the wind changed to north-west, the rain ceased and a sight was then first obtained of the neighbouring islands and of the town of Stromness, the latter of which from this point of view and at this distance presented a pleasing appearance.
