The discussion which followed was opened by Mr. Holt. He said that if
they were to have greater speed on the Atlantic, there was one point
which was not alluded to in the paper, and that was the total
abolition of cargo on board the great passenger steamers. If vessels
were built solely for passenger traffic, they would be able to insure
greater speed by reason of the greater slightness in build and the
additional space at the command of the designer. The existing Atlantic
express steamer was far too heavy, and might, if cargo was dispensed
with, be made with finer lines and more yacht-like. He looked on the
