Frank B. Black, was one of Sackville’s business elite, having several businesses and investments in the region. Among these interests was a farm and in this document and others making up this file, we see evidence that he maintained a correspondence with officials in the New Brunswick Department of Agriculture reporting on pest damage and seeking advice on how to combat them. In this memo he describes his experience with the army worm over several seasons. Apart from the challenges posed by these pests, the exchange highlights the increasing role of government agencies and their technical experts in the support of farming.
