While nitrogen is critical for all plants, they are unable to utilize organically bound nitrogen in soils. Therefore, the majority of plants obtain useable nitrogen through nitrogen fixing bacteria and the microbial decomposition of organic matter. In the majority of cases, symbiotic microorganisms directly furnish plant roots with inorganic forms of nitrogen. More than 80% of all land plants form intimate symbiotic relationships with root colonizing fungi. These common plant/fungal interactions have been defined largely through nutrient exchange, where the plant receives limiting soil nutrients, such as nitrogen, in exchange for plant derived carbon. Fungal endophytes are common plant colonizers. A number of these fungal species have a dual life cycle, meaning that they are not solely plant colonizers, but also saprophytes, insect pathogens, or plant pathogens. By using 15N labeled, Metarhizium infected, wax moth larvae (Galleria mellonella) in soil microcosms, I demonstrated that the common endophytic, insect pathogenic fungi Metarhizium spp. are able to infect living soil borne insects, and subsequently colonize plant roots and furnish ts plant host with useable, insect-derived nitrogen. In addition, I showed that another ecologically important, endophytic, insect pathogenic fungi, Beauveria bassiana, is able to transfer insect-derived nitrogen to its plant host. I demonstrated that these relationships between various plant species and endophytic, insect pathogenic fungi help to improve overall plant health. By using 13C-labeled CO2, added to airtight plant growth chambers, coupled with nuclear magnetic resosnance spectroscopy, I was able to track the movement of carbon from the atmosphere, into the plant, and finally into the root colonized fungal biomass. This indicates that Metarhizium exists in a symbiotic partnership with plants, where insect nitrogen is exchanged for plant carbon. Overall these studies provide the first evidence of nutrient exchange between an insect pathogenic fungus and plants, a relationship that has potentially useful implications on plant primary production, soil health, and overall ecosystem stability.

According to legend, the Burning Springs were discovered by early natives in the Niagara Peninsula. Bridgewater Mills was built on the site of the spring. During the excavation of the factory; workmen uncovered the spring. Samuel Street and Thomas Clark recognized the potential of this as a tourist attraction so they built a wooden shelter over the spring. The spring was covered with a barrel with a pipe protruding from it. This became the first tourist attraction at Niagara. The Cave of the Winds was a cavern located behind the Bridal Veil Fall. It was originally named the Aeolus Cave. In 1920, a sudden rock fall from the ceiling killed 3 tourists. The cave was destroyed in 1955 as it was deemed dangerous. The captain of the Maid of the Mist was usually a farmer who owned the land where the ship docked. In 1846, the first steam powered Maid of the Mist was launched. By 1848, the first suspension bridge was built over the gorge and the main purpose of the Maid of the Mist was no longer to carry people who needed to travel, but now the focus was on people who wanted to view the Falls at close range.

William Frederick Haile was born in Putney, Windham County, Vermont on November 4th, 1791. He was raised in Fairfield, Herkimer County, New York. At the age of 21 he entered the United States Army. He served in the War of 1812 as a lieutenant in the 11th United States Infantry. He was severely wounded in the Battle of Lundy’s Lane [not mentioned in this memoir]. After the war he settled in Plattsburgh, New York and became a lawyer. He was a judge from April 1837 to March of 1843. He was also the fifth collector of customs for the District of Champlain. He died on October 1861 at the age of 69. This document was written for the children of William Frederick Haile in January of 1859 [as noted on p.23]. The memoir ends in July of 1814 before the Battle of Lundy’s Lane. Haile’s memoir is laced with names of military personnel and he expresses his opinions freely.

- The first part of the document traces Mr. Haile’s lineage. His father, James Haile was a farmer. His grandfather, Amos Haile was a sailor for the early part of his life. He was placed on a British man-of- war in about 1758. He escaped and settled in Putney. (p.1) - His father’s mother’s maiden name was Parker. His mother’s maiden name was Campbell. Her father was a captain in the Revolutionary Army. (p.2) - His earliest memories revolve around the death of his aunt and the funeral of General Washington (although he did not witness this). At the time, his father was a Lieutenant in a regiment militia of Light Dragoons who wore red coats. (p.3) - In 1804, an addition was added to the Haile house which necessitated that William was to stay home to help with the building. He continued to study and read on his own. He was particularly interested in Napoleon Bonaparte’s victories. In that same year he was sent to Fairfield Academy where Reverend Caleb Alexander was the principal. (p.4) - On June 1, 1812, William was appointed as an Ensign in the Infantry of the Army of the United States. He was put into the recruiting service at Nassau (20 miles east of Albany) where he remained until September. (p.4) - He was assigned to the 11th Regiment of the W.S. Infantry and directed to proceed to Plattsburgh to report to Colonel Isaac Clark. (p.7) - He was assigned to the company commanded by Captain Samuel H. Halley who was not in the best of health and often absent. For a good part of the time William was in charge of the company. (p.8) - The 11th Regiment was encamped beside the 15th Regiment commanded by Col. Zebulon Montgomery Pike [Pike’s Peak was named after him]. Col. Pike generously drilled and disciplined the 11th Regiment since their officers didn’t seem capable of doing so. (p.8) - The first brigade to which William’s regiment was attached to was commanded by Brigadier General Bloomfield of New Jersey. Brigadier Chandler of Maine commanded the second brigade. (p.9) - At the beginning of November, Major General Dearborn took command of the army. He had been a good officer in his time, but William refers to him as “old and inefficient” earning him the nickname “Granny Dearborn” (p.9) - On November 17th, 1812, General Dearborn moved north with his army. The troops ended up in Champlain. There was no fighting, only a skirmish between a party of men under Colonel Pike and a few British troops who he succeeded in capturing. (p.10) - The troops were moved to barracks for the winter. Colonel Pike’s troops were put into suitable barracks and kept healthy but another part of the army (including the 11th Regiment) were sent to a barracks of green lumber north of Burlington. Disease soon broke out in the damp barracks and the hundreds of deaths soon followed. One morning, William counted 22 bodies who had died the previous night. He puts a lot of this down to an inexperienced commanding officer, General Chandler. (p.11) - At the beginning of 1813, William was stationed as a recruiter on the shore of Shoreham across from Fort Ticonderoga. In February, he returned to Burlington with his recruits. In March he received an order from General Chandler to proceed to Whitehall and take charge of the stores and provisions. In April and May it was decided that his half of the regiment (the First Battalion) should march to Sackett’s Harbour, Lake Ontario. They arrived at Sackett’s Harbour about the 10th of June, a few days after the Battle of Sackett’s Harbour. (p.12) - He was camped near the site of Fort Oswego and got word to head back to Sackett’s Harbour. A storm overtook the schooner that he was on. (p.14) - William was involved in the Battle of Williamsburg (or Chrysler’s Farm) which he calls a “stupid and bungling affair on the part of our generals”.(p. 18) - General Covington was wounded and died a few days after the battle. (p.19) - William speaks of being ill. The troops were ordered to march to Buffalo, but he is able to go to his father’s house in Fairfield where his mother nursed him back to health (p.23) - Upon arrival at Buffalo, the “old fogy Generals” were replaced with younger, more efficient men. (p.25) - On page 27 he sums up a few facts: In 1812, the army was assembled on Lake Champlain with the intention of capturing Montreal, and then Quebec. That year, under General Dearborn the army marched as far as Champlain, then turned back and went into winter quarters. In 1813, the army was assembled at Sackett’s Harbour and that year the campaign ended at French Mills which was 70 or 80 miles from Montreal. In 1814, the army at Buffalo were some 400 miles from Montreal with still the same object in view. - He says that these facts make “a riddle – difficult to explain”. (p.27) - On the evening of July 2nd they embarked on the boats with the objective of capturing Fort Erie. The enemy were all made prisoners of war (p.27) - On July 4th they went to Street’s Creek, 2 miles above the Chippewa [Chippawa] River (p.28) - Page 29 is titled The Battle of Chippewa [Chippawa] - He speaks of 2 drummers who were fighting over the possession of a drum when a cannonball came along and took of both of their heads (p.29) - He proclaims that this was one of the “most brilliant battles of the war”. The battle was fought and won in less than an hour after they left their tents. He credits General Scott with this success and states that was due to his rapid orders and movements. (p.30) - The dead of the battle remained on the field during the night. He describes this as quite gloomy seeing friend and foe lying side by side. At daybreak they set to work digging trenches to bury the dead. (p.31) - Colonel Campbell was wounded and advised to have his leg amputated. He refused, and subsequently died. (p.32) - It is said that the British threw several of their dead into the river and they went over the Falls. (p.32) - His troops repaired the bridge over Chippawa which the enemy had partially destroyed and then pursued the British as far as Queenston Heights. (p.32) - On pages 33 and 34 he speaks about meeting an old friend of his, Philip Harter. - The account ends at Queenston Heights
