ENGINEER SOLDIERS.

By legislation at the late session of Congress the number of these was increased to four companies of 150 men each. Prompt steps were taken to recruit these companies by establishing recruiting stations at a number of the principal cities and towns of the country, and for a time the result was quite successful, but the necessities of the case made it unavoidable to break up these stations and bring the recruits with the recruiting officers into service. Owing too this check the whole number of enlisted men of the corps amounted on the 1st July last to 276 men only. Recently, however, under the regulations permitting recruits to be drawn from the volunteer troops, large numbers have been added to the force, which now is not far from its limit of 600 men. The battalion of four companies is serving with the Army of the Potomac.
