gade at Gettysburg, and, from December, 1863, till April, 1864, was at the head of the middle department, with headquarters at Baltimore. He then participated in the Richmond campaign in May and June, 1864, and commanded provisional troops against Gen. Jubal A. Early, in July, 1864. From that date until August, 1865, he commanded a brigade in Baltimore. He was mustered out of service on 25 Aug., 1865, and returned to the naval school in Annapolis. He was retired on 4 Aug., 1876. In addition to a tract entitled "Manual of Naval Batteries," he has published "Exercises in Small Arms and Field Artillery, arranged for the Naval Service" (Washington, 1852).—His son, James Booth, explorer, b. at the U. S. naval academy, Annapolis, Md., 9 Oct., 1852; d. at Cape Sabine, arctic regions, 9 April, 1884, was sent to a private school at Bethlehem, Pa., and later to St. John's college, Annapolis. After some experience in farming and as a railway surveyor, he was commissioned 2d lieutenant in the 23d U. S. infantry, 1 Oct., 1873. He served in the west for the succeeding seven years, and became proficient not only in ordinary military duties, but also in surveying, telegraphy, and phonography. He volunteered for duty with
the Lady Franklin bay expedition (see Greely, Adolphus W.) and, as second in command, was intrusted with the most important field-work of the expedition, also assisting in the magnetic observations. In preliminary sledging he was in the field twenty-two days after the sun had left for the winter, and six days before its return. In March, 1882, Lieut. Lockwood, with a dog-sledge, made a few days' trip across Robeson channel to Newman bay in temperatures ranging from 30° to 55°, Fahrenheit, below zero. On 3 April, 1882, he started on the successful journey that fixes his fame as an arctic explorer. Using a dog-sledge and assisted by eight men, he reached Cape Bryant, on the north Greenland coast, on 1 May, and thence he sent back the man-sledges, and with dog-sledge, accompanied by Sergt. Brainard and the Eskimo Christiansen, started northward. The party reached Cape Britannia on the fifth day's march, and thenceforward travelled along land before unknown. Lockwood island, in latitude 83° 24′ N., longitude 40° 46′ W., the most northerly point on land or sea that ever has been attained by man, was reached on 13 May, and two days were spent in observations. The Greenland coast yet trended to the northeast, being visible as far as Cape Washington. 83° 35′ N., but there was no land to the north or northwest within the sixty miles that were visible from the summit of an adjacent cliff. Vegetation was comparatively abundant, while birds were seen and animal traces found. Fort Conger was again reached on 17 June. In sixty days Lieut. Lockwood travelled 1,069 statute miles and experienced temperature as low as 49° below zero, Fahrenheit, without serious accident. His discoveries extended the boundary of known lands 28 miles nearer the north pole, and added 125 miles of entirely new coast line to Greenland. The farthest point that was seen on the Arctic ocean was within 350 miles of the pole. A most promising attempt in 1883 to surpass the latitude of 1882 failed only through the disintegration of the polar ice-pack. Later in the year, despite his misgivings, Lieut. Lockwood, "with Sergt. Brainard, supplemented Lieut. Greely's discoveries of 1882 by crossing Grinnell land and reaching, by dog-sledge, a point on the coast, 50 miles beyond Mount C. A. Arthur, which had been attained by that officer on foot. In the retreat of the Greely expedition in the autumn of 1883, and in the terrible winter at Camp Clay, Lieut. Lockwood bore his part bravely. His remains were brought to the United States by the relief expedition under Capt. Winfield S. Schley, and buried in the grounds of the naval academy. See Charles Lanman's "Farthest North" (New York, 1885), and "The Official Report of the Lady Franklin Bay Expedition" (Washington, 1887).
LOCKWOOD, Homer Nichols, topographer, b. in Victory, Cayuga co., N. Y., 23 June, 1833. He was educated in Fulton, N. Y., and from 1858 till 1865 travelled in the southern states, and the West Indies. He aided in building the New York Southern-Central railroad in 1865-'71, and in 1866-'7 was a member of the legislature. Since 1880 he has resided in New York city.

LOCKWOOD, Samuel, clergyman, b. in Mansfield, Nottinghamshire, England, 20 Jan., 1819. He was graduated at the University of the city of New York in 1847, and at New Brunswick theological seminary in 1850. He was licensed to preach by the New York classis of the Dutch Reformed church, and held pastorates in Cortland, N. Y., Gilboa, N. Y., and Keyport, N. J., until 1867, when he was appointed superintendent of public instruction for Monmouth county, N. J., which office he has since held. For some time he was lecturer on natural sciences in Rutgers college grammar-school, and he has contributed to scientific journals discoveries in botany, paleontology, and zoölogy. He received the degree of Ph. D. from the University of the city of New York in 1869, and is now (1887) president of the New Jersey state microscopical society and of the American postal microscopical club. His writings include "Temperance, Fortitude, Justice" (New York, 1855); "Abnormal Entozoa in Man" (1881); "The American Oyster" (Trenton, N. J., 1883); "The Life of an Oyster" (New York, 1885); "Raising Diatoms in the Laboratory" (1887); and "Animal Memoirs" (1889).
LOCKWOOD, Samuel, naval officer, b. in Connecticut, 24 Jan., 1803. He was appointed midshipman in the U. S. navy on 12 July, 1820, and in 1826 served in the sloop "Warren," which was engaged in suppressing piracy in the Greek waters. He was promoted lieutenant in 1828, and in 1847-8 commanded the steamers "Petrel" and "Scourge," assisting in the capture of Vera Cruz, Tuspan, and Tobasco. In 1850 he was made commander, and in 1857 commodore. In 1861-'2 he had charge of the blockade of Wilmington and Beaufort, and of York river and Newport News. Com. Lockwood also assisted in the capture of Fort Macon. He was retired, 1 Oct., 1864.
