Some ecological effects of beaver upon the watersheds in the Porcupine Hills, Alberta /

This ecological investigation of the beaver (Castor canadensis canadensis Kuhl) was part of the Eastern Slopes (Alberta) Watershed Research program conducted during the summers of 1968 . 1969 . 1970. and 1971 . A soil particle size analysis indicated that soil heavy with clay was used by the beaver for construction purposes in the Porcupine Hills . Examples were given of the beaver controlling erosion with the construction of dams . and also causing erosion to occur . However . in general . the beaver slow down soil erosion and decrease the loss of soil from this region. The beaver utilized measureable amounts of herbaceous vegetation . However, the utilization of herbs by the beaver requires further investigation. A system of ex~sures and enclosures of herbaceous vegetation plots was used to study the utilization of sedges , grasses , and forbs . The beaver indicated stronger species preference for willow as compared to aspen . The size preference for willow was in the 1.0 to 10.0 centimeters basal diameter classes , while the beaver utilization of aspen indicated a preference for the largest trees with basal diameter greater than 20.0 centimeters. Willow was the most important plant in the low lying areas with regard to distribution, abundance and to produce sustained yield. The beaver used this plant for food and construction throughout the study area. The distribution of aspen was limited. and this species did not appear to produce more than one crop in the lifetime of a beaver colony. Nine out of 15 woody plant types were sampled by the beaver in this region. A plot-intercept transect technique was used for systematic vegetation sampling of the woody vegetation in six intensively studied watersheds. The beaver population of the Porcupine Hills region of SW-Alberta is believed to depend upon the chinooks. During the 1971 ground census, a total of 60 active beaver colonies were tallied on the 930 square kilometers large study area. The beaver of the region were not found to store large food caches during fall and winter, however, they are believed to collect feed periodically throughout the winter months. It was observed that the severe winter in 1968-69, reduced by 27 per cent the number of active beaver colonies within the study area. The Porcupine Hills region had 0.07 beaver colony per square kilometer in 1971, a low density of beaver colonies due to the rough topography of the area. However, the importance of the beaver ponds was somewhat clarified as they provide increased moisture, which lessens the fire damage, and store water for wildlife and cattle in the area. Meteorological data was collected by the author in collaboration with the Department of Transport.

The investigation of edge effects within ragmented forest islands in Short Hills Provincial Park

It has been well documented, within the field of landscape ecology, that terrestrial fragmentation contributes to increased heterogeneity at the landscape level. It has also been observed that elevated areas of edge habitat occur within fragmented landscapes. Spatial and temporal edge effects were investigated in four areas designated as Nature Reserve Zones within Short Hills Provincial Park, near St. Catharines, Ontario. Random sampling along exposed edges was performed on trees and saplings, at 5 and 25 ill edge depths, using the point-centred quarter method. Diameter at breast height (dbh) and distance from point measurements were used to establish relative density, dominance, frequency and importance value. One-way analyses of variance were used on dbh measurements of tree species and Chi-Square contingency tables were used on size class distributions of saplings species to determine significant differences between 5 and 25 metres. Qualitative comparisons of importance values were also used to determine differences between 5 and 25 metres as well as between trees and saplings. These statistical and qualitative comparisons suggest that a significant overall spatial edge effect is currently exhibited by fragmented wooded islands within the park. The major species of the park, Acersaccharuln, may be exhibiting a temporal edge effect. The heterogeneous nature of the park may be of importance in understanding this area as a complex, ecological system. It is possible that the remaining forest tracts of the park have been affected, and continue to be affected by previous disturbances. Based on these findings, recommendations are made to the Ontario Ministry of Natural Resources concerning the management of Short Hills Provincial Park in accordance with their 1990 proposed Management Plan.

Letter from George Cran regarding a Christian mission in India, 1803.

George Cran was the son of a farmer in the parish of Forgue in Aberdeen Shire, Scotland. He became a member of the church at Huntley, Scotland where his devotion to God inspired him to become a Sunday school teacher. He subsequently became a member of the London Missionary Society. In 1801 he was sent to study at the seminary in Gosport, England where he spent two to three years. His desire was to preach Christ to the “heathens”. Messrs. Ringeltaube, Des Granges and Cran were designated to work in India. No ships for the East India Company would grant passage to missionaries due to the open hostility of the government therefore they set sail from Copenhagen on April 20, 1804 and reached Tranquebar on December 5th, 1805. Cran and Des Granges were designated to supervise the churches in Tinnevelly and they were to begin a mission among the northern Circars. This would have meant that they would have to work in two different places which would have separated them by over 500 miles. The society didn’t seem to be aware of the vast hindrances that the missionaries had to face. Cran and Des Granges decided instead to work in Vizagapatam where they were welcomed by many of the European residents. They conducted English services for which they were paid a monthly salary by the governor. They also conducted services for the natives and opened a school for native children. By November of 1806 a mission house had been built and a “charity” school for Eurasian children was opened. Cran and Des Granges were also diligently studying the native language and they began to translate the Bible into Telugu (spoken by the Hindus who live along the lower basins of the Kistna and Godaveri Rivers). In November of 1808 Cran was almost killed by a fever which left him severely weakened. He was only partially recovered, but accepted an invitation by the general who commanded the local district to accompany him on a journey around the province. The journey proved to be too much for Cran and he died on January 6th, 1809. He is buried at Chicacole, India. He is remembered for his successful work at Vizagapatam and his translation of the Bible. The fact that it was 27 years after the arrival of Cran before a single native was converted attests to the fact that this was a very difficult undertaking. The London Missionary Society was formed in 1795 in England by evangelical Anglicans and nonconformists. It is a non-denominational society and now forms part of the Council for World Mission. with information from The Voice of God to the Churches a Sermon on the Death of George Cran, Augustus Des Granges and Jonathan Brain by David Bogue and The History of the London Missionary Society 1795-1895 by Richard Lovett

Secret Military Mission

A set of instructions titled "Secret" directing the 15th Garrison Battalion, dated 22 June 1918. The instructions are for the next morning (June 23rd) and direct the Battalions movements, location and dress. The troops are to be in full marching order with steel helmets at back of pack and the directions lead them to Lederzeele - St. Momelin road.
