To the patriotic business men of Philadelphia. : Three times our state has been invaded by the enemy; every emergency has found us unprepared to meet the foe--and for want of a force of cavalry to herald his approach his foot has been upon our soil without any warning to his presence. To meet this deficiency--remedy this now apparent evil, 1000 mounted men, bold riders, are wanted, and have been called for by Gen. Couch. ... You are earnestly invited to contribute immediately, ... all monies received for the company will be paid over to the treasurer, E.S. Hall, cashier of the 7th National Bank, No. 216 Market St., and orders drawn on him for the purchase of the horses. ... Any other information will be given at, and all communications can be addressed to the law office of the undersigned, No. 204 South Fifth St / Fred'k A. Van Cleve, Capt. commanding. Frank L. DeGour, 1st. Lieut. Alonzo Gordon, 2d Lieut.
