Water Chestnut, Assabet River 2015

Water chestnut rosette, top. Each plant can create up to 5-10
rosettes; each rosette creates 5-15 seeds.
Water chestnut, an invasive water plant, has a nature akin to lily pads on steroids, growing rapidly in nutrient-rich fresh water ponds, lakes and slow-flowing rivers. Unchecked, it will almost completely cover water surfaces, making boating, swimming and fishing impossible. The dense floating mat of overlapping leaves also blocks sunlight penetration, causing oxygen deprivation lethal to fish and other animal life. In addition to this ecological horror story, the large, sharply pointed seeds, which mature in early August, fall to the bottom, and can cause painful wounds if stepped on.

bladders on stems, to keep the plant floating. Seeds not yet created.

(This species, Trapa natans, is not to be confused with the edible water chestnut common to Chinese cuisine.) Water chestnut was initially brought to the Harvard University Botanic Garden, possibly from southeastern Europe or western Asia. In the 1870's staff gardener Louis Guerineau took it upon himself to throw seeds into Fresh Pond and other Cambridge waterways. This came to the attention of Medford-based botanist George E. Davenport, who decided to bring seeds and live plants to his friend Minor Pratt, in Concord. He and Pratt seeded a pond near the Sudbury River, and he suspected Pratt conducted additional distributions. Thus, Cambridge was point zero and Concord the plus one. Current distribution ranges from Canada to Maryland, and westward into New York and Pennsylvania.

As early as 1879 there was a concern voiced by botanist Charles S. Sargent, Director of Boston's Arnold Arboretum, that this non-native species threatened to become a nuisance, based on dense growths reported in Cambridge. Davenport fessed up in the Bulletin of the Torrey Botanical Club, Vol. 6, page 352: "I have several times had plants of Trapa natans that were collected in the vicinity of Boston, during the present year, brought to me for identification, and I have entertained no doubt as to the manner of its introduction into waters outside Cambridge Botanic Garden. But that so fine a plant as this, with its handsome leafy rosettes and edible nuts, which would, if common, be as attractive to boys as hickory nuts now are, can ever become a 'nuisance' I can scarcely believe."
Filling baskets with water chestnut, Assabet River 2015.  By the end of
the day's efforts this patch was all pulled up and disposed of.

This past Saturday a doughty band of about 16 volunteers, organized by OARS (Organization for the Assabet Sudbury & Concord Rivers), launched canoes onto the Assabet River from the property of Bob Collings, in Stow, to put in three hours pulling water chestnut plants. I was there as a first-time participant. What this involved was paddling upstream about one-third of a mile. Two occupants per canoe would steer into an area with plants to pull them by hand, each yank resulting in a dripping, muddy mess dropped into laundry baskets in the middle of the canoe. After a half-hour of this, the laden canoes would be paddled back to the launch site, the baskets lugged ashore to a compost pile, the canoes bailed out, the process repeated. Messy, messy, messy! The harvest was sixty full laundry baskets.  

Years of these visits, conducted every July before the nuts mature and fall to the bottom, have done a great job of eradicating the plants from long stretches of the Assabet River and reducing density in the still impacted parts. Surveillance visits are repeated each year, because while most seeds sprout next spring, some are still viable as much as 8-10 years later.

Worst case: without the past, present and future efforts of volunteers from non-profit organizations the Assabet River upstream of the Ben Smith Dam could have become blanketed shore to shore with water chestnut. A few rosettes would have broken loose from anchoring stems, floated down the canal, and ending up infesting Maynard's mill pond.

To get an idea of how bad it can get, Vermont spends over half a million dollars a year hiring companies with mechanical harvesters to manage the worst parts of Lake Champlain, plus paying dozens of people to do hand-pulling in less-infested waters on the big lake and elsewhere. The 2013 report described 1,200 tons collected by the harvesters and more than 21 tons by hand.

Locally, mechanical harvesters have been needed on badly impacted parts of the Sudbury River. Heavily infested areas can also be treated with chemical herbicides, but these are non-selective, killing all plants. Researchers are looking into biological controls (plant diseases or insects from parts of the world where water chestnut originated), but are wary about introducing anything that is not species-specific.

OARS volunteers were out in boats again in July 2016, removing water chestnut from the section of the Assabet River between Maynard and the Powdermill Dam, in Acton.

Gruber Bros. Furniture

Gruber Bros. Furniture, Main Street, Maynard, MA (2015)
 The fire of 1934 changed everything. Julius and Benjamin Gruber had bought the business from Alfred T. Haynes in 1917, followed by buying the building in 1919, and were operating as Gruber Bros. Furniture on the first floor. Upstairs was Riverside Theatre (motion pictures), managed by Samuel Lerer. Elsewhere in the building were the Waino Williams Bakery, King & Huggins liquor merchants, and various offices of the Town of Maynard. The fire started in the back of the building around 4:30 AM on a Saturday morning and was not entirely extinguished until after noon. The re-build was to a smaller building, currently with Gruber Bros. Furniture as its sole occupant.

A pre-fire photo hangs in the front window along with a plaque from the Maynard Historical Commission. The original building, three stories tall, much modified through the years, was erected in 1868. A large meeting hall on the second floor served as host to Maynard’s first town meeting, in 1871.   

When Julius and Ben retired the business fell to Burton “Burt” Gruber, Julius’ son. A newspaper clipping from The Beacon, Nov 18, 1982, recounts a story about Burt selling $69 worth of office furniture on credit to a couple of guys starting up a new business in the mill. The business was Digital Equipment Corporation and one of the shoppers was Ken Olsen. When Burt retired operation of the business went to his nephew, Joel B. Cohen, son of Burt's sister Jeanette (Gruber) Cohen and Sidney Cohen. [Burt died in 2006, age 94 years.]

The Gruber family was an active part of a small Jewish community in Maynard. Family records suggest that brothers Max and Eli Gruber came to the United States from Russia circa 1880, with both of them ending up in Maynard some time later. Ellis Island as the east coast immigration arrival site did not start operating until 1892, so a good guess is that the Grubers left port from Hamburg, Germany and landed in Boston (rather than New York, the major destination for Jewish immigration from 1890-1925). Max's oldest daughter was born in Europe, but the subsequent four children, including Julius and Benjamin, were born in the U.S. The oldest sister married Samuel Lerer, local store owner, movie theater operator, and a Selectman of the Town of Maynard.

The Gruber family was instrumental in forming the Maynard Hebrew Society, which in 1921 bought a house on Nason Street and had it moved to Acton Street to be the home of Rodoff Shalom Synagogue. Prior to that the members had been served by a visiting rabbi, holding services in space rented in the meeting hall of the International Order of Odd Fellows, on Nason Street. Rodoff Shalom Synagogue existed through to 1980, when it merged into Congregation Beth Elohim, in Acton. In a temple newsletter, Adam Jacoby remembered, “In 1980 we built a new building and marched the Torah from Maynard to Acton under a chuppa [canopy] with shofars [horns made from rams' horns]. I was one of the shofrot during the walk.”

Gruber Bros. Furniture intends to close its doors later this year, thus bringing a closure to three generations and 98 years as a family business. As Joel Cohen put it, "When I was 16 years old my mother sent me over to the store to help with a furniture delivery. Now, 54 years and one hip replacement later, it's time for me to get off the truck and retire." The middle photo shows Cohen leaning on a stand-up desk that spans the width of the office. When asked the history of the desk he replied that it was in the office when his family bought the business in 1917. Future use of the building, which includes a mural-decorated warehouse building in back, is unknown.
