Soon after my arrival at Camp Allegheny in the month of May 1800 I became acquainted with Lieut. Zebulon Montgomery Pike of the 2d Regt. U. S. Infy, he was shortly afterwards appointed Adjutant of the Regiment, in which Capacity he served during the Years 1800 & 1801. No officer could be more attentive prompt and efficient in the execution of the several duties of his office--nor was there any more emulous to acquire a perfect knowledge of the Military profession, nor more zealous, ardent and persevering in the pursuit of scientific improvement. It was these qualities and disposition of mind that laid the foundation of the subsequent Character and fame of Zebulon M.

At that period the most vexatious evil and obstacle that attended the maintenance of discipline in the Army was the general and extensive use of Ardent Spirits, Whiskey among the Men which was constantly being introduced in Camp by the Men & Women attached to the service and other hangers on around the Camp--On one occasion returning to Camp from Pittsburgh about ten o'clock in the evening Pike and myself being desirous of detecting the Soldiers in their Clandestine manœufvres in the introduction of whiskey approaching the
