In The Engineer for September 17, 1880, we did our best to place a true statement of the facts concerning the Rocket before our readers. In... more...

IRON PILE PLANKS IN THE CONSTRUCTION OF FOUNDATIONS UNDER WATER. The annexed engravings illustrate a method of constructing subaqueous foundations by the use of iron pile planks. These latter, by reason of their peculiar form, present a great resistance, not only to the vertical blow of the pile driver (as it is indispensable that they should), but also to horizontal pressure when excavating is being... more...
