A mill-owner, hearing of the depths I had found, thought it untrue, because, from his acquaintance with the locks, the fine sand could not lie at such a steep angle.But the deepest lake, in proportion to its area, is not as deep as most people imagine. If its water is drained to take a look, what is left is not a very deep valley.They are not cup-shaped like valleys, for this lake, which is already surprisingly deep for its size, cuts through the center only as deep as a shallow dish.Most of the lakes and marshes have been drained, and what remains is a meadow, no lower than we often see.William Gilpin is excellent, and always accurate, in describing landscapes, and standing on the tip of Loch Fein in Scotland, he describes, "This bay of salt water, sixty or seventy fathoms deep, four miles wide " about fifty miles long, and surrounded by high mountains on all sides, he added: "If we could, when the floods, or whatever convulsions of nature cause them, before the currents rush in, it must be What a dreadful gap!"
"The lofty mountain rises so high,
The bottom of the low-lying lake sinks so low,
Wide and wide, a good river bed——. " If, however, we apply the ratio of the shortest diameter of Feyn's Loch to Walden, where we already know that the longitudinal section is only a shallow dish, it is four times shallower than Walden.Such would be the exaggerated horror of the gap if the waters of Finn's Loch were to pour out at once.Undoubtedly, many of the smiling valleys stretching out the cornfields are "dreadful gaps" exposed by receding torrents, though the insight and foresight of a geologist would have been necessary to convince the unsuspecting inhabitants that this fact.Among the hills low on the horizon the discerning eye can discern a primitive lake, and the plain need not be raised later to conceal its history.But like people who have worked on the road, it is easy to know. After heavy rain, you can know where the depression is by looking at the mud puddle.This means that the imagination, if it is allowed a little indulgence, sinks lower and rises higher than nature.Therefore, the depth of the ocean may be insignificant in comparison with its area. Having measured the depth of the lake on the ice, I could now determine the form of the bottom much more accurately than I could measure the bay without ice, and was surprised to find it generally regular.In the deepest part, there are acres of flat ground, scarcely inferior to the plowed fields in any sun and wind.In one place, I picked a line at random and measured thirty rods, but the change in depth was only one foot; generally speaking, in a place near the center of the lake, moving in any direction, the change of one hundred feet would be enough for me. It can be known in advance that it is only about three or four inches in depth.It is customary to say that even in such a calm lake with a sandy bottom there are deep and dangerous holes, but if this had been the case, the water would have flattened all the unevenness of the bottom.The regularity of the lake bottom, its conformity with the shore and the adjacent mountains, is so perfect that a bay in the distance can be measured from the opposite side of the lake, and its direction can be known by observing its opposite bank.The headlands became sandbars and shallows, and the valleys and valleys became deep waters and lakes. I found this astonishing consistency even more when I drew pictures of the lakes at a scale of ten rods to an inch, noting their depths at more than a hundred places.I found that the place where the greatest depth was recorded was just in the center of the lake. I used a straightedge to draw a line at the longest distance, and then drew a line at the widest place. It happened to be at the intersection of the two lines, and although the center of the lake was fairly flat, the outline of the lake was not very regular, and the difference in length and breadth was measured from the recesses, I said to myself, who knows whether this implies that the ocean is the deepest Is the situation here the same as that of a lake and a mud puddle?Does this rule also apply to high mountains, considering high mountains and valleys as relative?We know that the narrowest point of a mountain is not necessarily its highest point.
