and in ten days more was mounted and in the field. He rendered active and valuable services, especially to BuelPs army in Kentucky, and was engaged in several severe skirmishes and battles, receiving two disabling wounds. His regiment was engaged in resisting Morgan's raid, and fol- lowed him until his capture at Buffington island. In 1863 Col. Jacob was elected lieutenant-governor on the ticket with Thomas B. Bramlette. Col. Jacob fiercely assailed the emancipation proclama- tion as an act of violated faith toward the friends of the Union cause, and of injustice to the owners of property in slaves in a loyal state. He advo- cated the election of Gen. McClellan to the presi- dency in 1864, and censuring the administration in unsparing terms, while canvassing the state, was arrested by order of Gen. Burbridge, and sent through the Confederate lines to Richmond. He afterward received an unconditional release from Mr. Lincoln, and returned to Kentucky, where he now (1887) resides in Oldham county.

JACOBS, John Adamson, educator, b. in
Leesburg, Va., 19 Aug., 1806 ; d. in Danville, Ky.,
27 Nov., 1869. He was taken by his parents in
infancy to Kentucky, was left an orphan at thir-

obtain an education. He studied in Centre col-
lege, Ky., and at eighteen years of age was made
superintendent and teacher of the deaf and dumb
in the institution that had been recently estab-
lished under state auspices in Danville. To fit
himself for this service he spent eighteen months in
the deaf-mute institution at Hartford, Conn. Until
1854 he was allowed any profits that might accrue
on the boarding department proceeds : but in that
year he voluntarily gave it up, thus saving at the
time $2,500 per annum to the state. He died
after forty-five years of service in the institution.
Mr. Jacobs published a manual of lessons for his
Kupils (1834), and "Primary Lessons for Deaf-
lutes," which received many commendations on
both sides of the Atlantic (2 vols.. 1859). — His

uncle, he was unanimously chosen by the trustees
to succeed him as superintendent of the institution.
