Edward H. Tracy, of New York, has invented, and patented this week, an improvement in the above, whicji is designed to obviate the difficulty attending the washing; away of the foundations of breakwaters. The invention consists in constructing the breakwater, dam, or other structure, with two or more longitudinal compartments, which may be subdivided into cells, and having inner compartments provided with a flooring, the outer compartment being open at its lower end, so that in case the filling of the outer compartment escapes in consequence of the washing away of the foundation directly beneath it, the structure will be retained or supported by the inner compartment or compartments while the front compartment is being re-filled, and until sufficient filling has escaped to form a good foundation.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
