Business Change.

Mr. Charles H. Mason, for some time past the efficient commercial traveler for Saxton & Thompson, flour dealers, Troy, has severed his connection with that firm to engage in business with his grandfather, Mr. Henry J. Mason, the well known furniture dealer and undertaker. He will act as accountant for the house and it is his intention to acquire a knowledge of the business in all its details. The young man has ample ability and all the qualifications necessary for a successful business career, and his hosts of ardent friends will wish him god-speed in his new enterprise.

Century of Service Since 1861.... four generations of the Mason family home have aided their neighbors in Lansingburgh and Troy in times of bereavement. Founded at 588 Second Ave. The funeral parlors remained at that address until destroyed by fire in recent years.  The present parlors were opened at 8-109th St. in 1954. We extend our congratulations to the members of the "Uncle Sam" Committee who devoted time and effort unselfishly to bring national recognition to our city as the "Home of Uncle Sam". The Genealogy of our Concern through 100 Years is as follows: Henry J. Mason...Founder Thomas J. Mason Charles H. Mason, Sr. Charles H. Mason, Jr. Charles H.
