The plow works of Wyley & Conklin having been sold to Henry Robinson, the manufacture of grates and mantles for dwelling houses was commenced. Mr. Robinson was succeeded by Thos. Southard, dee'd, in 1840, who commenced the manufacture of stoves. Some eight or ten years afterwards, upon the death of Mr. Southard, the present farm of Southard, Robertson & Co. came into possession, and the imprint of the People's Stove Works may now be found upon work of their manufacture all over the land.

In the winter of 1826-27, Seth Hoyt erected part of the buildings now known as the Peekskill Plow Works and commenced the manufacture of plows and plow castings on an extensive plan. A few years afterwards Mr. Hoyt died and the property was purchased by Truman Minor and Frost Horton, who, in 1835, formed a co-partnership under the firm name of Minor & Horton, and three years afterwards the firm became Minor, Horton & Co., who commenced the erection of extensive additions and enlarged their business to such an extent that their wares were shipped to almost every part of the world. This firm continued the business for thirty years, when it was merged into a joint stock company, now known as the Peekskill Plow works.

The foundries now in operation are The People's Stove Works, (Southard, Robertson & Co.), the Union Stove Works, (Hill's), National Stove Works (Stanford's), the foundry of Montross, Lent & Pollock, the American Stove Works, and the Peekskill Manufacturing Company, (Seymour's). In brisk seasons these shops employ from 400 to 600 men.
