The action sparked what became known as the Powder Alarm, in which thousands of colonists, believing an attack had been made, marched on Boston and Cambridge. In 1832 Colonel Samuel Jaques, a well known horticulturalist and breeder of livestock bought Ten Hills Farm and made it famous as a stock farm. In 1877, the farm was destroyed and much of the high ground was used to fill in surrounding marshlands. In 1900, the Metropolitan Park Commission acquired land along the Mystic River in Ten Hills and built Melrose Street, now called Shore Drive. In 1908, the City of Somerville built a public bath house on Melrose Street which became a very popular spot for bathers in the Mystic River. A planned amusement park was never built, but a new bathhouse along the shore of the river was built sometime between 1925 and 1947. In 1928, the City of Somerville bought the site for the purposes of building an elementary school, and in 1930, The Charles A. Grimmons Elementary School was opened for students.
