Manuscript copy of a certificate signed by Daniel Chamier in New York, certifying that in his capacity as Commissary General he had appointed Samuel Rogers as Deputy Commissary of Stores and Provisions at Perth Amboy beginning in December 1776 and continuing until the following May, "during which time the great Number of Troops in Garrison there and at Brunswick being upwards of Ten Thousand Men, rendered it necessary to place very large Quantities of Provisions in his care." Chamier praises the work done by Rogers but notes that bad weather had brought on a "Rheumatic Complaint" that would require him to be relieved of his duties.
