gineer in charge of the work. After making surveys for railroads in various parts of the country, he became interested in the manufacture of iron, and introduced several improvements, including the utilization of the waste gases from blast and other furnaces. In 1845-'52 he engaged in this manufacture in Maryland, and then built the New York “Crystal Palace.” He afterward became president of the New Jersey zinc company, built their works at Newark, and originated and successfully developed the manufacture of “spiegel” iron from the residue of the zinc ore. He then engaged in coal-mining, but failing health forced him to go to Europe, where he lived, most of the time in Paris, till his return to New York in 1885. He published a translation of the principal historical, political, and diplomatic writings of Machiavelli (4 vols., Boston, 1882).
DETRE, William, missionary, b. in France in
1664 ; d. in South America. He entered the Jesuit
order, and obtained permission from his superiors
to devote himself to the Indian missions. He was
sent to South America either in 1701 or 1700, where
his zeal and ability attracted attention, and he was
made superior-general and visitor of all the mis-
sions on the Amazon for over an extent of more
than 3,000 miles. As soon as he had made himself
thoroughly familiar with the Inca, or Quichua, the
most common language in that country, he suc-
ceeded in translating the catechism into eighteen
languages spoken by the tribes under his jurisdic-
tion. He was appointed rector of the College of
Cuenga in 1727. He is said to have died at an ad-
vanced age, but the date is not given. He sent to
Europe the celebrated map of the Amazon, drawn
by Father Fritz, who died in his arms. He left an
interesting " Uelation," written in 1731, giving
curious details about the savage tribes that dwell
on Ihe banks of the Amazon. It is inserted in the
23d volume of the " Lettres edifiantes."

DEVENS, Charles, jurist, b. in Charlestown, Mass., 4 April. 1820; d. in Boston. 7 Jan., 1891. He was graduated at Harvard in 1838, studied in the law-school at Cambridge, and practised from 1841 till 1849. He was a member of the state senate from that county in 1848 and 1849. From 1849 till 1853 he held the office of U. S. marshal for the district of Massachusetts. During this period Thomas Sims was remanded as a fugitive slave, and Mr. Devens, in obedience to what he considered the exigencies of his office, caused the process to be executed. After the rendition he endeavored, through the Rev. L. A. Grimes, in 1855, to obtain the freedom of Sims, offering to pay whatever sum was necessary for the purpose, but the effort was fruitless. At a later period, hearing that Mrs. Lydia Maria Child was making applications for money to purchase the freedom of Sims, Mr. Devens addressed her a letter requesting the return of the sums she had collected for this purpose, and that she allow him the privilege of paying the whole sum. To this Mrs. Child assented ; but, before the affair could be arranged, the war rendered negotiation impossible. Sims was eventually liberated by the progress of the National armies, was pecuniarily aided by Mr. Devens in establishing himself in civil life, and at a later period appointed by him, while attorney-general of the United States, to an appropriate place in the department of justice. In 1854 Mr. Devens resumed the practice of law in Worcester. On 19 April, 1861, he accepted the office of major, commanding an independent battalion of rifles, with which he served three months, and in July was appointed colonel of the 15th Massachusetts volunteers. With this regiment he served until April, 1862. and was wounded in the battle of Ball's Bluff. He was made brigadier-general in 1862, commanded a brigade during the Peninsular campaign, was disabled by a wound at
