In 1889, school children from schools across New York state were solicited to express their preference for an official state tree. The young students made their preference known and the sugar maple was lauded as the state tree of New York.
The sugar maple remained in a place of prominence among New Yorkers for sixty years. In spite of the favorable 1889 vote by school children, the sugar maple never received an "official" designation from the state legislature. Proponents of the red oak sought to take advantage of that fact. In 1949 a challenge emerged with a legislative proposal to name the red oak the official state tree.
It looked like New York's long affair with the sugar maple might be upset by an "official" act of the New York State Legislature. The oak tree seemed to be riding a wave of popularity. Maryland had adopted the white oak in 1941 commemorating its huge Wye Oak, at Wye Mills, on the Eastern Shore. Connecticut had adopted the white oak, in 1947, in recognition of its historic Charter Oak.
Though supported by tree lovers and nurserymen, legislation designating the stately red oak (Quercus borealis) the official state tree failed to win approval by the legislature.
Nine years later, in 1956, New York Governor William Averell Harriman asked the State Assembly to validate the choice the school children had made in 1889. He asked the legislature to officially designate the sugar maple the official state tree of New York.
When Vermont Governor Joseph B. Johnson heard about the proposal to name the sugar maple New York's state tree, he sent a rather confrontational telegram to New York Governor Averell Harriman expressing outrage that New York would even consider naming the sugar maple their official state tree.
Johnson telegraphed a protest that "the sugar maple has been the state tree of Vermont since March 16, 1949, and the public won't be fooled into believing that the Empire state can compete with Vermont maple products."
"However, Vermont will be willing to share its sugar maple with New York if you are willing to prove in competition that New York's maple- products taste even one-half as good as Vermont's maple products."
("Vermont-N.Y. Maple Syrup Battle Simmering to Boil", 1956)
In the telegram, Governor Johnson accused New York of "trespassing on hallowed ground" but offered to withdraw his protest if Harriman admitted that New York's maple syrup tasted only 'half as good as Vermont's." 
Harriman promptly challenged Johnson to enter Vermont's maple sugar in a "free and fair taste test" at the annual New York State Maple Sugar Festival in Cooperstown April 6-7.
"Should you in the meantime wish information as to the quality of the New York product," Harriman added, "I refer you to the many Vermonters who import thousands of gallons of New York state's maple syrup every year."
("Vermont-N.Y. Maple Syrup Battle Simmering to Boil", 1956)
And, Harriman pointed out, New York school children had already selected the sugar maple as the state tree on Arbor Day in 1889! The current legislation, he said "merely deposit in our archives a fact which has long been graven on the hearts of our people." 
In the New York State Assembly, legislators were up in arms.
"Gentleman, this is war!" declared Assemblyman Eugene F. Bannlgan. 
From Vermont came further assaults on New York's actions.
During a speech in Worcester, Massachusetts, Vermont Governor Johnson accepted Harriman's challenge and agreed to a face-off at the New York State Maple Sugar Festival in Cooperstown.
The field of "maple war" competitors was growing. New Hampshire, Maine, Ohio and the Province of Quebec, Canada joined what some called a "good-natured feud."
The Governor of New Hampshire, Seymour Lane Dwinell, upped the ante.
Governor Durnell [sic] says both Harriman and Johnson "are way out on a maple limb." Both governors, he said, "are trying to borrow New Hampshire's reputation for producing the highest quality maple syrup."
("Cooperstown Invites Governors to Fete", 1956)
From Ohio, Governor Frank John Lausche weighed in.
The cry reached the ears of Governor Lausche, who replied in a letter to a New York lawmaker "You can save yourself a lot of anxiety and bring to an end this dispute by recognizing that while the maple syrup of New York, the New England states and Quebec is good, that of Ohio is the finest in the world."
("Vermont Maples are Tops Says GVA's Ansheles", 1956)
New Hampshire State Representative Perkins Bass proposed that un-biased commission be appointed to pass judgment on each state's product, then went on mock the proposition that any other product could match the high standard set in New Hampshire.
"The preposterous claims of Ohio and New York of producing the best maple syrup in the nation are unbelievable to anyone who has had the privilege of tasting our New Hampshire maple nectar."
("N. Hampshire Enters Maple Syrup Battle", 1956)
He then offered a list of New Hampshire representatives to form the "un-biased" commission.
The Lethbridge Herald, Alberta, offers some tart commentary from Sherbrooke, Quebec.
"It's a wise, wise governor who knows his own syrup," said one authority here.
Robert Boright, one of Quebec's biggest exporters of maple syrup, said most of the syrup sold under American label is imported from Quebec—and even then is "watered down" for retail sale.
"I only hope the governors will remember that it is the syrup, not the label, that matters," said a Sherbrooke producer, with a sly grin.
("Highlighted in the News: Stickey Subject", 1956)
The Evening Observer, Dunkirk, N. Y., reported that a confident Governor Harriman was steadfastly convinced that no one could match the quality of New York's maple syrup.
Harriman obviously does not think this is possible for he has put up a "Governor's Cup" to be awarded in competition at the State Sugar Festival in Cooperstown next April.
Brimming with confidence, the Governor's office said Saturday the competition would be open to all states and "friendly nations." Food editors will taste-test the syrup at the festival, which is scheduled for April 6-7.
("State's Maple Syrup "Best In World"-Ave", 1956)
“Announcement was made this week that Gov. Averell Harriman, New York State’s leading maple booster, has issued invitations to nine other states, and to the premier of Quebec, to attend the New York State Maple Festival at Cooperstown on April 6 and 7,” The Star reported on March 16. The festival would hopefully answer the question as to which state or province had the best maple syrup.
(Simonson, "Backtracking: In Our Times: Election, maple syrup, schools made local news in '56", 2016)
The taste-off at the New York State Maple Festival would include production from New York, Vermont, Pennsylvania, Massachusetts, Ohio, Wisconsin, Maine, Michigan, Minnesota and Canada's Quebec Province.
Meanwhile in Albany, on January 31, 1956, the New York Senate approved the bill proposing that the sugar maple tree be designated the official state tree and forwarded it to the Assembly for consideration.
The New York State Maple Sugar Festival and maple syrup taste-off loomed ahead. Both New York Governor Harriman and Vermont Governor Johnson remained certain that their state's product would come out on top.
Even prior to arriving at the festival, the judges, food editors Isabel McGovern, Mary Hornaday, Margaret Pettigrew, Alice Peterson and Ida Bailey Allen began making their way through various syrupy recipes including "maple barbecued ribs; sweet and sour skillet chicken; maple corn muffins; scalloped sweet potatoes and pineapples in syrup; French dressing with maple syrup; maple charlotte russe (a type of desert), and maple fluff." 
Evidently, their sensitive palates could not distinguish between two top contenders. Calling it a tie, they awarded the top spot to Vermont and Michigan. New York came in third.
We have been unable to find ranking information for the remaining seven contestants; Pennsylvania, Massachusetts, Ohio, Wisconsin, Maine, Minnesota and Canada's Quebec Province.
The top products awards went to Dewey Lyman of "Breezy Hill Farm, White River Junction, Vermont, and Clive Willis, Bellevue, Michigan.
Governor Averell Harriman accepted the results graciously. Because there were two first-place winners, he promised to provide a Silver Governor's Cup to each.
Though Vermont came out ahead of New York this year, the victory was slight.
After the results of the competition were announced, undaunted, Governor Harriman went on to sign the tree bill, approved by the New York State Legislature, making the sugar maple the official state tree of the State of New York on April 10, 1956.
