On leaving the Rock at night we had the greatest difficulty in boarding the _Pharos_ with two boats containing upwards of thirty-two persons, as the vessel rolled so heavily, that there was great danger of the boats being thrown right upon her deck. Next morning (8th August) we landed, with some sea running, about nine o’clock, before which hour it was impracticable, owing to the surf in the landing creek. Our first work was to prepare the tackling for landing the heavy materials from the _New Leven_, which came up about eleven o’clock, and was made fast by a warp to the _Pharos_. We next took means for fixing the smith’s forge on the Rock and preparing the fixtures for the crab, which stood on the point of rock to the westward (see Plate III.), and served chiefly for raising the beams of the log-house into their places. The greater part of the day, till half-past eight in the evening (when it became dark), was spent in lining off with accuracy the site of the supports of the wooden barrack, and in landing and fixing by strong lashings to the Rock, all the principal timbers and iron fixtures. The spot in which the framework of the first barrack was placed, will be seen by reference to Plate III. The Rock was at this place a good deal lower than the site afterwards adopted for the barrack. The high water of spring-tides rose 2¹⁄₂ feet upon the legs or main beams; but this site had many advantages, as it left more room for operations at or near the Tower itself than could have been obtained in any other position. ~Sudden gale, and great peril to the vessels.~ ~Reach Hynish in safety.~
