FROM EAST TENNEssKE-Mr Robert Garter.
who has arrived At Cincinnati direct from
Greenyiile, reports that there are very few
troops in Upper East Tennessee. All the avail
able force in that section OF the country had
been ordered to Tuiiahoma ana Murfreesboro'
An order had been issued for all the cavalry in
East Tennessee to report at Knoxviise, % be
dismounted. There were some 300 cavalry An
Hancock and Hawkins counties, who gAye out

vile 10 be dismounted, in pursuan Of tho
order TO that effect There Were some 600 troops
at Greenyille, but these were under orders for
Tullahoma. There are some two regimeute Al
kingston, Roane county, and a heavy force.at
Chattanooga The Rebel newspapers say that
their grand stand is 10 be made at Tullanoma,
and that Only small force has been thrown
out at Murfreesboro' as felnt and 8 check o,
the Federal forces. Mr.. Carter also says that
the inhabitants Of East Tennessee are no, re-
spending very readily TO the conseript law.
and that the Confederacy have, lust az this
time, too much business on their hande TO en-
force it; and that thousands of Union meu ar.
