strings: Mr. Editor: From present indications we have every reason to believe that Mr. Douglass will contest the right of Mr. Stuart to a Seat in Congress. We deem it a matter of great importance to the Whig party of this District that they should be prepared to meet such contest. The importance of the decision of that contest is increased by the doubt which at present exists as to which party will have the ascendency in the next Congress. In this state of uncertainty one vote may become of the utmost importance to the sustaining of those great principles for which the Whig party are now contending. To prepare ourselves for the contest and to solicit your aid in so doing by engaging your assistance in the collection of proofs to the following facts, are the objects of this communication.
