A Boy's Life and One Tragic Summer on Mt. Washington by Joseph McQuaid. 
McQuaid, publisher of the New Hampshire Union Leader and Sunday News, grew up in the newspaper business. But his teenage years were spend high up in the White Mountains, working on the world-famous Mt. Washington Cog Railway for the Teague family.
In this memoir, McQuaid writes with humor and wistfulness of a wonderful era that time and circumstance have all but erased, and of Colonel Arthur S. Teague, whose recognition as one of America's outstanding World War II heroes is long overdue.
Cog Days is also the story of one terrible summer that claimed the lives of Colonel Teague and a daughter, and ended with the worst accident in the Cog's storied and colorful 150 years of operation.
