In "Bulletin 3" of the New Hampshire Experiment Station is the following:
As our New England markets demand a round or oblong white potato, we recommend for main crop the planting of such varieties as the Green Mountain and Delaware, or varieties that closely resemble them.
As seedsmen are each year introducing and selling at fabulous prices new and untried varieties, the most of which are soon dropped from their catalogues and forgotten, we advise growers to depend on standard sorts that have been fully tested and found adapted to their soil and market, and allow their experiment station to test the novelties for them, thus preventing a large annual waste of time and money."
