Hugh Alexander Papers, 1811-1816 [photocopy]

Hugh Alexander, b. 1780 arrived in Niagara shortly after his birth. He attended school and later apprenticed as a clerk. In 1797 he was granted 200 acres of land in Bertie township and became a merchant and trader in Fort Erie. He was the owner of a sailing vessel, the Chippawa, which he used to transport goods in the area. The ship was lost and/or confiscated as a result of War of 1812 skirmishes on Lake Erie. By 1812 Hugh Alexander was in business together with his brother Ephraim. The Alexander’s storehouse, store and house were burned by the British military when they abandoned Fort Erie ahead of the invading American military in late May 1813. At the time of the burning, Hugh Alexander was engaged as a Lieutenant with the 3rd Lincoln Militia. Prior to this Hugh Alexander had established a second mercantile in Stamford, opposite the green. Misfortune was to strike at this location as well when the British military abandoned the whole of the Niagara area to the invading American forces and the Stamford location was looted. After the end of the hostilities Alexander went on to rebuild his storehouse in Fort Erie and to re-establish his store in Stamford. Hugh Alexander died on November 2, 1817 and is buried in the Stamford Presbyterian Cemetery. Source: George A. Seibel, The Niagara Portage Road: 200 Years 1790-1990.

Welland Canal Survey of Lands Alexander Nickerson 1826

Survey map and description of Alexander Nickerson's land created by The Welland Canal Company. Included is a written description of the land along with a drawing of the land. Noteable features include; locks no. 7, 8, 9, 10, line between Soper and Phelps land, concession line, Millard, sawmill, line between Phelps and Dittrick's land. Surveyor notes are seen in pencil on the map. The deed for the land is dated August 23, 1826. This land is owned by Alexander Nickerson, taken to be used by the Welland Canal Company and at the time of the survey was in the posession of Oliver Phelps. The land totals 15 acres, 2 roads, and 20 perches.

Group-invariant solutions of semilinear Schrodinger equations in multi-dimensions

Symmetry group methods are applied to obtain all explicit group-invariant radial solutions to a class of semilinear Schr¨odinger equations in dimensions n = 1. Both focusing and defocusing cases of a power nonlinearity are considered, including the special case of the pseudo-conformal power p = 4/n relevant for critical dynamics. The methods involve, first, reduction of the Schr¨odinger equations to group-invariant semilinear complex 2nd order ordinary differential equations (ODEs) with respect to an optimal set of one-dimensional point symmetry groups, and second, use of inherited symmetries, hidden symmetries, and conditional symmetries to solve each ODE by quadratures. Through Noether’s theorem, all conservation laws arising from these point symmetry groups are listed. Some group-invariant solutions are found to exist for values of n other than just positive integers, and in such cases an alternative two-dimensional form of the Schr¨odinger equations involving an extra modulation term with a parameter m = 2−n = 0 is discussed.

Letter - R. Woodruff to Alexander Hamilton

Letter to Alexander Hamilton of Queenston from R. Woodruff of St. Davids. The letter states that Mr. Woodruff is not able to send butter as requested. Mr. Hamilton received credit for the butter and Mr. Woodruff cannot say when they will have turkeys. The letter is slightly stained and has a hole in the upper right hand corner. This does not affect the text, Dec. 22, 1824.
