Gnarly ancient sugar maples are sentinels. They may grow for 200 years and slowly decline for another half century.

Plagued by unseen internal maladies, the ancients display familiar symptoms of aging: thinning of fine twigs in the leafy canopy - like male pattern baldness. Loss of large limbs in a winter ice storm is a catastrophic injury, like a broken arm. Mushrooms sprout from cracks in the craggy bark. Woodpeckers extract carpenter ants from the heartwood. Hammered and hollow, old maples decline in vigor each year. In time, squirrels holes replace tap holes. Sap buckets gracing old roadside maple trunks in March become more a quaint memory.

Yet perhaps you've seen how a young maple sapling can sprout from the living roots of its parent tree? More accurately, it's a clone: an exact genetic replica of the ancient tree. The sprout grows quickly, nourished by the established network of roots. Hardwoods practice this resurrection trick, regenerating sprouts from cut stumps in a process that foresters call "coppice regeneration."

Same tree, new century.

A fitful start

When we finally boiled sap for the first time last weekend, it felt just like that: resurrection, with continuity in the experience.

Our lightly used maple equipment - call it "the rig" - came to us from Hinesburg, Vt. Its former owner died suddenly late in 2012. His widow is now selling their farm and wished for the family's maple legacy to live on. We offered to buy all the equipment and provide a fine home in a classic new post and beam sugarhouse overbuilt by eager, ambitious and perhaps naïve New Hampshire sugar-makers.

We carted untold labelled boxes of equipment, supplies and plumbing fittings back home to New Hampshire - mainlines, tubing, bulk tanks, pumps, taps, special tools, filters, canning supplies and more.

We planned a "soft opening" for this first season operating unfamiliar equipment in the new sugarhouse. This is a project a decade in the planning and three years of weekends in actual construction, from logging and milling pine for the timber frame to hanging the last roof shingles. Boiling actual maple sap now represents the culmination of a project I call the "$10,000 waffle."

Maple sap runs are intermittent. Fitful late February and early March temperatures didn't remain in the "Goldilocks zone." Maple sap runs best when nighttime low temperatures are in the 20s and daytime high temperatures are in the 40s. It was too warm overnight when daytime temperatures spiked to 60 degrees, and then too cold by day when overnight temperatures dipped to low single digits.

With the thermometer at 8 degrees, we broke ice to pump cold maple sap beneath the surface from the outdoor bulk tank buried in remnant snow up to the sugarhouse loft feeder tank. The sap immediately began freezing in the newly-installed hoses leading to the wood-fired evaporator. My son, Cody and I were determined to boil the first 160 gallons we'd collected from our 100-plus taps. We re-routed sap directly into the cold pan and fired-up the arch - a risky gambit that frozen sap lines would thaw and flow before we reached boiling point.

It worked. The sugarhouse warmed as the wood-fired arch creaked and the smokestack pinged as the rig came to life. At its glowing heart is the shiny stainless steel evaporator we purchased from Hinesburg. We watched as steam billowed from the rooftop vent doors and sparks spilled from the chimney stack each time we stoked the fire. A milestone.

A box of supplies contained the glass maple syrup grading jars and fragile hydrometers that measure sugar content of clear maple sap and thicker, hot finished syrup. We found an old-fashioned kitchen egg timer in the box with seven minutes marked on the face of the dial. It turned out to be the exact interval for stoking wood in the arch and adding a tiny drop of defoamer to the rolling boil in the sap pan.

Our first-ever boil yielded 6 pints of finished syrup - 0.75 gallons - along with 40 gallons of half-cooked sap leftover in the evaporator for next time. As the rig cooled down, we washed up and took stock of what worked best and what needed improvement. We began a new sugarhouse journal to record the gallons collected prior to boiling, total gallons processed to steam and the yield - if any - in finished syrup. We've got big plans for more taps, more efficient collection, easier filtration. But we'd settle for warmer temperatures and several more good sap runs.

Our first efforts felt guided by a sense of sugaring continuity; our confidence nourished by roots beyond our prior experience. Afterward, we received a copy of the sugarhouse journal from Hinesburg. It's a sap-bucket-treasury of weather notes, stories and statistics. Handwritten notes reveal the personality of the family's annual maple sugaring operations we're now fortunate to perpetuate.

Same rig, different farm.

To experience maple sugaring with your family, join the Forest Society on Saturday, March 18, during a special "Five Hikes in Five Weeks" series tour of "The Maple Guys" maple sugarhouse in Lyndeborough. To register, visit http://bit.ly/2mlO7Xs.

Maple tours continue each weekend at The Rocks Estate in Bethlehem. The "New Hampshire Maple Experience" spring tour dates are March 18, 19, 25 and 26, and April 1. Join guided tours of the sugaring operation, horse-drawn and tractor drawn rides, tap a maple tree with the group, tree identification, the history of sugaring or attend a demonstration of cooking with maple, visit the NH Maple Museum and sample maple syrup, sour pickles and cider donuts.
