lost heavily, was drawn off in good order; Tallard's was almost

BLENNERHASSETT, HARMAN (1765-1831), Irish-American lawyer, son of an
Irish country gentleman of English stock settled in Co. Kerry, was born
on the 8th of October 1765. He was educated at Trinity College, Dublin,
and in 1790 was called to the Irish bar. After living for several years
on the continent, he married in 1796 his niece, Margaret Agnew, daughter
of Robert Agnew, the lieutenant-governor of the Isle of Man. Ostracised
by their families for this step the couple decided to settle in America,
where Blennerhassett in 1798 bought an island in the Ohio river about 2
m. below Parkersburg, West Virginia. Here in 1805 he received a visit
from Aaron Burr (q.v.), in whose conspiracy he became interested,
furnishing liberal funds for its support, and offering the use of his
island as a rendezvous for the gathering of arms and supplies and the
training of volunteers. When the conspiracy collapsed, the mansion and
island were occupied and plundered by the Virginia militia.
Blennerhassett fled, was twice arrested and remained a prisoner until
after Burr's release. The island was then abandoned, and Blennerhassett
was in turn a cotton planter in Mississippi, and a lawyer (1819-1822) in
Montreal, Canada. After returning to Ireland, he died in the island of
Guernsey on the 2nd of February 1831. His wife, who had considerable
literary talent and who published _The Deserted Isle_ (1822) and _The
Widow of the Rock and Other Poems_ (1824), returned to the United States
in 1840, and died soon afterward in New York City while attempting to
obtain through Congress payment for property destroyed on the island.

BLERA (mod. _Bieda_), an ancient Etruscan town on the Via Clodia, about
32 m. N.N.W. of Rome. It was of little importance, and is only mentioned
by geographers and in inscriptions. It is situated on a long, narrow
tongue of rock at the junction of two deep glens. Some remains of the
town walls still exist, and also two ancient bridges, both belonging to
the Via Clodia, and many
