The line at the western end passes over a flow-moss from 30 to 40 feet deep, for a distance of 2 miles. Here the rails had to be literally floated on rafts of timber, and continued floating for some time after the trade had commenced, until at length, by continued pouring in of hard material—such as gravel, stones, &c.—this part of the road is now comparatively firm and solid. It had, however, for some months after the trains commenced to run, a very singular, and to many, an alarming appearance,—the engines and carriages, as they went along, causing a deflection of the platforms or rafts, of from 2 to 3 feet, which gradually rose to their proper level behind the train, exactly like a sluggish wave, as soon as the whole had passed over.
