Incendiaries at the Navy Yard.
--An attempt was made on Sunday last, says the
Portsmouth (Va.) Transcript of the 14th, to burn the
Saw Mill at the
South end of the
Navy-Yard, with the expectation, no doubt, of destroying therewith the other valuable buildings and property in the vicinity-Fortunately, however, the dense smoke arising exposed the vile attempt in time to prevent an extensive conflagration.
On examination it was found that a large pile of shavings and other combustible material had been placed directly under the most valuable part of the mill, and there fired.
It is rumored that very large rewards have been offered by the enemy to persons secretly in their employ, to destroy the property in this Yard, and it is hoped that the utmost vigilance will be maintained, that the miscreants may be detected and dealt with as their conduct merits.
