I knew also that she had been built as a pleasure-boat for the accommodation of only six persons upon the Severn.
I determined, therefore, to suspend my belief till I could take the admeasurement of each vessel.

This I did; but lest, in the agitation of my mind on this occasion, I should have made any mistake, I desired my friend George Fisher to apply to the builder for his admeasurement also.
With this he kindly complied.

When he obtained it he brought it me.

This account, which nearly corresponded with my own, was as follows:--In the vessel of twenty-five tons, the length of the upper part of the hold, or roof of the room, where the seventy slaves were to be stowed, was but little better than ten yards, or thirty-one feet.

The greatest breadth of the bottom, or floor, was ten feet four inches; and the least five.
Hence, a grown person must sit down all the voyage, and contract his limbs within the narrow limits of three square feet.
