An illustration of the mouth of the Miami River. The Miami River is a river in Florida that drains out of the Everglades and runs through downtown Miami, Florida. The 5.5 mile (8.9 km) long river flows from the terminus of the Miami Canal at Miami International Airport to Biscayne Bay. It was originally a natural river inhabited at its mouth by the Tequesta Indians, but it was dredged and is now polluted because of its proximity to the Miami-Dade County. The mouth of the river is now home to the Port of Miami and many other businesses whose pressure to maintain it has helped to improve the river's condition.

"Siege of Island No. 10, on the Mississippi River- night bombardment by the Federal mortar boats, ten o'clock P. M., March 18th, 1862. On the 16th of March, 1862, the mortar fleet and the gunboats, consisting of the <em>Cincinnati, Pittsburg, St. Louis, Silver Wave, Carondelet, Mound City, Conestoga, Louisville, Rob Roy, Alps, Wilson, Lake Erie, Great Western</em> and <em>Torrence</em>, and nine mortar boats, arrived near the Point. These were accompanied by several tugboats. On the 18th they opened fire, which, after some hours' delay, was returned by the Confederate batteries. This continued for several days, with very little loss to the Federal troops, owing to the iron casing of the vessels. The study of mortar firing is very interesting. Our sketch represents the manner in which the smoke rolls, and a small column frequently splits out when the shell passes. The shell itself can be seen at night during its entire flight, the fuse having the appearance of a star, which appears and disappears as the shell rolls through the air, very like the twinkling of the celestial orbs. The explosion of the shell at night is a magnificent and fearful sight, sending a glow of surpassing brightness around it as though some world of combustible light had burst." &mdash; Frank Leslie, 1896

"And Tobias went forward, and the dog followed him, and he lodged the first night by the river of Tigris. And he went out to wash his feet, and behold a monstrous fish came up to devour him. And Tobias being afraid of him, cried out with a loud voice, saying: Sir, he cometh upon me. And the angel said to him: Take him by the gill, and draw him to thee. And when he had done so, he drew him out upon the land, and he began to pant before his feet. Then the angel said to him: Take out the entrails of the fish, and lay up his heart, and his gall, and his liver for thee: for these are necessary for useful medicines." Tobit 6:1-5 DRA

Right triangle ABC with angles A, B, C to be used for finding distance across a river. This is a trigonometry problem. Wishing to determine the width of the river, I observed a tree standing directly across on the bank. The angle of elevation of the top of the tree was 32 degrees. At 150 ft. back from this point and in the same direction from the tree the angle of elevation of the top of the tree was 21 degrees. Find the width of the river.

"Trout is a term applied generally to various species of fishes belonging to the salmon family. The best-known species, and that which par excellence receives the name, is the common trout, a fish which inhabits clear and running streams. The average weight of the common trout is from three-fourths to one pound. "&mdash;(Charles Leonard-Stuart, 1911)

"Desperate naval combat between the Confederate iron-plated ram <em>Arkansas</em> and the Federal gunboat <em>Carondelet</em>, at the mouth of the Yazoo River, Tuesday, July 15th, 1862. Next to the ever-memorable combat between the <em>Merrimac</em> and the <em>Monitor</em>, that of the <em>Carondelet</em> and the <em>Arkansas</em> was the most exciting. Like the former engagement, it ended in a drawn battle. On July 14th, 1862, the gunboats <em>Carondelet</em> and <em>Tyler</em> were sent by Commodore Farragut to survey the Yazoo River and ascertain the exact condition of the Confederate iron-plated ram <em>Arkansas</em>, about which there were various reports. They arrived at the mouth of the Yazoo, fifteen miles above Vicksburg, at seven o'clock in the evening, and anchored for the night. Next morning at daylight they tipped anchor and slowly steamed up the Yazoo, the <em>Tyler</em> considerably in advance. About two miles up the river smoke was seen across a little point of land, which, as Captain Gwin of the <em>Tyler</em> surmised, proceeded from the Confederate ram, now rapidly steaming toward the <em>Tyler</em>. In another moment a heavy report was heard from the enigmatical gunboat, and a huge round shot went howling over the deck of the <em>Tyler</em>. Captain Walke of the <em>Carondelet</em> ordered the <em>Tyler</em> to proceed with all speed to alarm the fleet and advise it to prepare for her approach while he engaged the Confederate monster. In ten minutes afterward the <em>Carondelet</em> and <em>Arkansas</em> were alongside each other, and the conflict commenced in earnest. The <em>Carondelet</em> commenced with her bow guns, striking her opponent with a rapidity and precision which the enormous strength of the iron plating alone prevented taking immediate effect. The <em>Arkansas</em> used in return her rifled and guns with terrible effect, some of the shots going right through the <em>Carondelet</em>. Seeing her inability to cope with her antagonist, Captain Walke ran the <em>Carondelet</em> alongside the <em>Arkansas</em> and grappled her. The order "Boarders away!" was instantly passed, and the crew of the Federal gunboat speedily mounted the deck of its adversary. When there they found no foe to engage. The crew of the Arkansas had retired below, and the iron hatches were closed, so that it was uttlerly impossible to go down and continue the action." &mdash;Leslie, 1896
