After undressing and climbing into the top berth, I read from about quarter-past eleven to the time we struck, about quarter to twelve. During this time I noticed particularly the increased vibration of the ship, and I assumed that we were going at a higher speed than at any other time since we sailed from Queenstown. Now I am aware that this is an important point, and bears strongly on the question of responsibility for the effects of the collision; but the impression of increased vibration is fixed in my memory so strongly that it seems important to record it. Two things led me to this conclusion--first, that as I sat on the sofa undressing, with bare feet on the floor, the jar of the vibration came up from the engines below very noticeably; and second, that as I sat up in the berth reading, the spring mattress supporting me was vibrating more rapidly than usual: this cradle-like motion was always noticeable as one lay in bed, but that night there was certainly a marked increase in the motion. Referring to the plan, [Footnote: See Figure 2, page 116.] it will be seen that the vibration must have come almost directly up from below, when it is mentioned that the saloon was immediately above the engines as shown in the plan, and my cabin next to the saloon. From these two data, on the assumption that greater vibration is an indication of higher speed,--and I suppose it must be,--then I am sure we were going faster that night at the time we struck the iceberg than we had done before, i.e., during the hours I was awake and able to take note of anything.
