There was a pair of children’s boots obtained from the Aleutian Islands. The said pair of boots was examined under the microscopes as to its components, and origin. Microscope for education of students and other science practitioners could be utilized on this matter. It was also treated in order to have it returned to its original appearance. The boots were obtained by the US Naval Exploring Expedition of 1838-1841 under the leadership of Lt. Charles Wilkes. The boots are made of caribou calf skin and seal skin with fur. Majority of the gut is coated with pigment and is hard to characterize.
An effort was done to ascertain every kind of hair and various components of the boots by means of microscopy under a microscope. Microscopy using a particular microscope for education of the individuals undertaking the examination was done. First, a list of fur-bearing animals that are aboriginal to Alaska and the Aleutians was gathered. A recognition key for fur of the Arctic could not be established and keys to other geographic locations were of limited application. Next, investigation of the hair using a reflected light microscope with low magnification and examination of mounted specimens in polarized light microscope at higher magnification was performed. Such things were done with the help of microscope for education of those investigating the components of the hair. The hair was evaluated with recognized specimens such as photomicrographs of identified hairs and real pelts from animals in the collection of mammals. The specimens were identified by means of microscopy using a microscope for education. Furthermore, a science expert on this field of biology was consulted for his opinion.
The caribou and seal fur are the most unique. Caribou guard hair is typified by its vacant center, round cross section and opacity. Once viewed in reflected light microscope at low magnification its surface seems pitted, more like an orange peel. Due to its unoccupied and frail nature, it frequently has distorted or trampled portions. Nevertheless, this examination can also be performed using the microscope for education or a teaching microscope. Moose, mountain goat and mule deer hair have analogous properties. The hairs utilized for the needlework are comparatively big in diameter and are said to come from the bell of the caribou, that is, the portion under the neck which is white and ruff-like. The caribou fur that was used for the major body of the boots is extra finer in diameter and has brown and white colors.
Seal guard hair is exemplified by its closely flat cross section. Every hair is narrow at the proximal end, broadens in the core and tapers to a fine flat point at the distal extremity. In reflected light microscope at low magnification, the hairs seem shiny and translucent, as if wet. Such view can also be observed using a microscope for education. The only other animal of the Arctic with hair of comparable look is the otter. Otter and seal fur can be distinguished in that the narrowness of the proximal end of a seal hair is just a minute part of the entire length of the shaft while otter hair displays a narrow proximal end for approximately half its length before widening to its optimum diameter as examined by means of microscopy using a microscope. No effort was done to pinpoint the species of the seal.
This kind of investigation of primordial item is being done in order to determine the lifestyle, crafts or technology of the individuals of a particular era, and to preserve their masterpieces for the next generation to witness.Read on this subject
