The great scare which took place along our seaboard cities when it was known that the Spanish fieet had started for America was no doubt largely responsible for the authorization by Congress in 1898 of four harbor defense monitors, one of which, the “Arkansas,” built at Newport News, is herewith illustrated. The others, the “Florida,” “Nevada,” and “Wyoming," were built at Elizabethport, Bath, Me., and San Francisco. The “Arkansas” is 252 feet long, 50 feet bea:n, and draws only 12 feet 6 inches of water. She is a typical monitor, with a freeboard of only a few feet and her main battery of two 12-inch guns is carried at a height of not more than 8 or 10 feet above the water. The belt, 11 inches in maximum thickness, 's 5 feet wide, half of this being below the water line. The deck is 1112 inches thick and the barbette and turret are protected by 11 inches of armor, all treated remaining three reserves are in the waters of the State of Washington and include islands, some being at the entrance to Puget Sound, while the others are on the southwestern coast of the State near the Oregon line. In forest preserves 480,451 acres have been added to the Stanislaus and Lassen Peak national forests in California, the addition to the Stanislaus forest lying in Calaveras, Tuolumne, and Mariposa counties.

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.

Thank you,
