August 19 {1857}. There are four great men whose haunts I mean to seek, and on whose footsteps I mean to stand: Newton, Shakespeare, Milton, and Johnson. To-day I told the driver to take me to St. Martin’s, where the guide-book says that Newton lived. He put me down at the Newton Hotel, but I looked in vain to its top to see anything like an observatory. I went into a wine-shop near, and asked a girl, who was pouring out a dram, in which house Newton lived. She pointed, not to the hotel, but to the house next to a church, and said, “that’s it – don’t you see a place on the top? That’s where he used to study nights.” It is a little, oblong-shaped observatory, built apparently of wood, and blackened by age . . . .” Blackened no doubt by the wood ash and soot found in the air throughout over-crowded nineteenth century London. We always think about London being very foggy in the nineteenth century but frankly a lot of it was wood and coal ash as the nineteenth century grew older, particularly as factories developed and belched all of that into the air – think Sherlock Holmes in the 1880s. But Maria Mitchell, while starting in Europe as a young woman’s chaperone, also knew that this tour of Europe was a great learning experience – the equivalent of a college education she could not have. Doors were thrown open to her around Europe – in particular at all of the observatories that dotted the continent. She was not just well-known – she was famous. JNLF

This is a blog of the past. I often think of this “story” when it’s hot and humid out. So here it is again. The past few weeks have been very un-Nantucket as far as the heat and the extreme humidity. When I was a child and even a teenager, I remember that we always wore long pants and even sweaters in the summer evenings on island. This does not seem to be the norm any longer unfortunately. The heat also leads me to think about staying cool and what generations before us did to preserve food. Long before modern refrigeration, ice was used for preserving foods. Although the use of ice brought an end to salting and drying fish for local markets, with railroad development and western expansion in the 1850s, salt fish was still being shipped to inland domestic markets as well as abroad. As the fishing industry grew on Nantucket and elsewhere, however, so did the need for ice to keep the catch fresh for market. On Nantucket, when a hard freeze produced ice of the necessary thickness, blocks were cut from Maxcey’s and Washing Ponds and the North Head of Hummock Pond and stored in nearby icehouses. This was a fairly long and tricky process that took skill to make sure the ice was the right thickness and that one did not fall through the ice. Mainland icehouses typically used sawdust for insulation, but Nantucket ice was insulated with beach grass, seaweed, and eelgrass—sawdust not being readily available here. The iceman would drive his cart around the streets with usually a gaggle of children trailing behind – or hitching a secretive ride on the back of the cart – hoping for a piece of ice to suck on and cool off with – back when something that simple was a pure delicacy. When electricity was introduced on Nantucket in 1889, cutting pond ice was no longer necessary. Captain John “Jack” Killen built the first ice-making plant, on Straight Wharf, opening it on May 5, 1902. Several other plants, including that of the Island Service Company, followed—all operating until the Great Depression. Nantucket’s early ice-making plants were established primarily for packing fish and shellfish, which were shipped in barrels or fish boxes layered with ice. Fishermen both on and off-island would stock up on ice before going out on long trips, and it is said that island ice was of a much higher quality than that from plants off-island—perhaps because of the purity of Nantucket’s water. Some people still cut ice. My parents had an elderly friend, now gone, and his family owned – and I assume still owns – a camp of cottages from the 19 th century up in New Hampshire. In the winter, the entire family shows up to harvest ice and store it in the icehouse. The ice is then used in each of the cottages during the summer since they have no electricity or plumbing. It is an art that is almost gone but happily there are still a few who have passed down the knowledge and skill for harvesting ice. I recently took a look at his obituary and was blown away – I remember him for ice harvesting – but wow what a life! One of service and seeking justice. JNLF

NANTUCKET, MA— Join the Maria Mitchell Association (MMA) as it hosts Maria Mitchell’s 208th birthday on July 31st on Vestal Street. Maria Mitchell’s birthday celebration is a free community event with astronomy and natural science activities, live animal displays, research demonstrations, summertime refreshments, an ice cream truck, and live period-inspired music by Susan Berman and Ray Saunders. Admission will be FREE to the MMA’s Vestal Street sites! This afternoon of Maria Mitchell themed family activities will be held Tuesday, July 31st from 3pm – 5pm on Vestal Street, with the lower portion of the street closed to traffic. Join us for this annual event that the MMA has been hosting since our founding. The MMA is named after America’s first female astronomer, Maria Mitchell. She is known for discovering a comet over Nantucket in October 1847. She went on to become the first female professor at Vassar College, where she was an inspiration to her students. She believed in learning-by-doing and in the capacity of women to achieve what their male counterparts could. “Miss Mitchell” was beloved by her students whom she taught until her retirement, due to failing health, in 1888. She died in 1889 and is buried beside her parents in the family plot at Nantucket’s Prospect Hill Cemetery. The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell.

Being Nantucket, we tend to stay cooler than the mainland in the summer though the humidity is often over the top. It often makes me think about people in the nineteenth century and earlier – heck, even well into the mid 1900s, and how they handled the weather. With climate change, we have warmed and our weather is more severe and volatile at times. Instead of a nice gentle rain, we get a deluge and the ground has trouble absorbing that sort of onslaught. But they did did still have heat and humidity – and think of a fire in the hearth all day and the bake oven – if it was a baking day. And now, think of the women standing in front of the firebox and bake oven, or even a cook stove later on. I am sure if the confines of their home, alone, les could be worn but for the most part, those women still had a lot of layers on. I am sure that a cloth dipped into or run under the mouth of the pump and wrung out gently – to keep as much as the cool, moisture as possible – was tied around a neck or stuffed down a dress front (or even in addition to the wet neckerchief). At the Mitchell House, we get a little of the feeling for this. We have no HVAC in the House so we rely on doors being open – with screens to keep the bugs out – and the roofwalk opened (also with a screen) so that air circulates throughout the House. Air can move nicely through – the heat rises, the air moves up and out of the roofwalk hatch very much as it might have in Maria Mitchell’s day. While we do not have the added (somewhat) drying benefit of the heat of the fire in the kitchen, we do have all of the original horsehair plaster, so the House does remain somewhat cooler and drier overall. But some days, the relative humidity does get up into the 90s in the House – that’s when I say, “Get out your umbrellas!” JNLF

NANTUCKET, MA— The Maria Mitchell Association’s (MMA’s) Nantucket Harbor water-quality monitoring buoy is now part of the Northeastern Regional Association of Coastal Ocean Observing Systems, known as NERACOOS. NERACOOS is one of eleven regional associations that make up the U.S. Integrated Ocean Observing System, or IOOS, NOAA’s national ocean-observing network for gathering and sharing ocean, coastal, and Great Lakes data. This connection means that real-time data from Nantucket Harbor are no longer held only within a local monitoring program. They are now available through the NERACOOS Mariners Dashboard, where scientists, resource managers, educators, mariners, and the public can view Nantucket Harbor conditions alongside other coastal observing sites from Long Island Sound through the Gulf of Maine. The monitoring buoy carries a suite of sensors that track changing conditions such as temperature, oxygen, acidity, nutrients, and underwater light. These measurements show what eelgrass, bay scallops, and other marine organisms are actually experiencing over time. “This is an important step because Nantucket Harbor is now part of a larger coastal observing system,” said Dr. Betsy Sherman, the Maria Mitchell Association’s Senior Marine Science Advisor. “Our data can be compared with data from other sites, used in regional analyses, and placed in a broader environmental context. We are not just looking at Nantucket Harbor in isolation.” The Nantucket Harbor buoy project has been supported by the Great Harbor Yacht Club Foundation, whose early investment helped make continuous water-quality monitoring in Nantucket Harbor possible. Additional support has been provided by the Remain Nantucket Fund at the Community Foundation for Nantucket, the Osceola Foundation, the Sociable Weaver Foundation, and through collaboration with the Town of Nantucket Harbormaster. The timing is especially relevant for coastal communities because NERACOOS is also leading the newly funded NSF Seafood Engine in New England, a regional effort focused on strengthening fisheries, aquaculture, seafood technology, and coastal economies. For an island community facing changes in water quality, habitat, fisheries, and climate, joining this regional network strengthens the scientific foundation for understanding and protecting Nantucket Harbor.

Finished. Finis. Completed. Done. Accomplished. The Mitchell House roofwalk is now done. Back to looking a bit more normal up on the ridgeline. But as I may have noted in the other post about the roofwalk, the one that was removed due to its condition and how it sat on the roof’s ridge was far from the original – or even a nineteenth century one. I am including an image from about 1908 or so in order for you to see the Mitchell House without a walk – even then. Now, an interesting fact is that I am able to date the undated photo because in the west image – where you see the open year – you can actually see the shadow of the Maria Mitchell Vestal Street Observatory – at the backside of the 1825 Kitchen. And given that shadow you also know its late afternoon since that side of the House, as noted, faces West. Another interesting feature is the long downspout – more like a side spout – that takes water from the front gutter, along the upper West façade of the House and across a window and then over the 1825 Kitchen roof where it terminated in a cistern – still in existence under the ground today.
