John F. Dryden,
The American Type of Isthmian Canal
“ Engineers of the highest standing at home and abroad have expressed themselves for or against one type or the other, but it is a question upon which no complete agreement is possible. In theory a sea-level canal has unquestionable advantages, but, practically, the elements of cost and time necessary for the construction preclude to-day, as they did in 1894, when the New Canal Company recommenced active operations, the building of a sea-level canal. ”
