usual last week. As well as creating terrible driving condi- tions the extremely large crystals combined with the weight and density of the snow bounced the light around until all other hues were absorbed. Says physicist and former Russell resident, Owen Clarkin, “The effects are complicated by specific conditions such as temperature,

RUSSELL l The unusually blue cast to the snow that fell in large quantities on Feb- ruary 27 is related to the large size of the snowflakes in that storm.

This photograph taken in North Russell shows some of the blueness of the snow which fell during the major snowstorm February 27.
In an article at Alaska Science Forum, seismologist Larry Gedney says, “When light passes through ice…the red light is absorbed while the blue is transmitted.” He further explains that the more the light is reflected between the crystals the more the longer wavelengths are absorbed, until only the blues (shortest visible wavelengths) are reflected back. This effect occurs in all snow and ice, giving snow its faintly blue cast. However, it was more pronounced than
crystal size, etc., but water (and hence ice) are both naturally very slightly blue, due to a vibrational overtone being the funda- mental cause; blue can become the pro- nounced observable colour under the right conditions.” The colour effect can still be seen by pok- ing a large hole in a fresh part of the snow. The colour in the hole is slightly reminiscent of a glacier’s exterior.

Ils étaient plus de 400 à s’être donné rendez-vous devant la Chambre des commune à Queen’s Park, à Toronto, le 28 février dernier. Des entrepreneurs en colère qui désirent renverser la loi 119 touchant tous les petits entrepreneurs de l’Ontario. Menée par Juliette Forgues (en mortaise), de Casselman, cette manifestation a attiré des entrepreneurs en construction de Prescott-Russel, Hamilton et Toronto. Randy Hillier, député conservateur du comté de Lainark, a déposé une loi, la loi 17, afin de contrer la loi 119. Ils ont su attirer l’attention des députés à l’intérieur puisque leur demande est à l’étude. Mme Forgues est satisfaite de cette manifestation même si plus de participants étaient attendus. Elle prépare toutefois plusieurs manifestations qui auront lieux dans d’autres grandes villes canadiennes.
