"As this trench filled with water, we began at the same point and dug a similar one on the south side, running east and west, and connected the first trench with the drain. The gravel slopes also to the west, and dips quite abruptly when at a distance of forty feet from the drain. When the trenches were dug a gravel slope at the south-east corner of the square prevented the water from running out of the first trench. I therefore had the earth turned over on this slope, when we found great numbers of stakes, with some brushwood, the earth being a peaty marl. "When clear of the slope there is a decided layer of brushwood about two feet thick, also studded with stakes, and along the inner side of the south trench we found a number of piles from five inches to seven inches in diameter, in a line, and mostly upright. One of these we got out quite perfect. It is of oak wood, four feet in length, six inches in diameter, and has a forked top which has apparently been intended for carrying a horizontal beam or support. The piles are about four feet apart. One had given way and been replaced. "As the trench is not exactly in a line with the piles, several are now left standing and partially exposed. In this portion of the digging, we found several bones of animals, a peculiar grinding-stone of whinstone or granite, almost semicircular in shape, 12 inches long by 7 broad, a flint core, a stone with the centre hollowed, a pounding or hammer stone, and two fragments of rude pottery, evidently British. "Hazel nuts are numerous; several I have picked out appear to have been opened by squirrels. "After making these discoveries I suspended work, as I felt that I should like some one acquainted with similar explorations to give an opinion with respect to the course I ought to adopt. "Whether the place is a lake-dwelling or not, further research will determine. It is undoubtedly a pile structure, and of a very early date. "At this season the spring-tides tend to impede further investigation, the water having risen to the height of 7 feet in the trenches on the 19th inst. And as we may hope for warmer weather with longer days, I shall probably defer further exploration until April. I believe I have discovered another similar place, but on a larger scale, and the timbers appear much larger. The two are not more than half a mile apart, and are situated on the same lake as the earthworks and mound at Skipsea (described in Poulson's _Holderness_). In the meantime, any suggestions you may favour me with will be gladly received by yours very faithfully, "THOMAS BOYNTON. "DR. MUNRO, _Kilmarnock_." _Concluding Remarks._
