Trumpeter Swans Threaten Extinction In Canada And West
Scientists report wild trumpeters in Canada and hundreds thriving on western wildlife refuges may be last hope for the species. A. A. Allen recorded a 1937 rescue of two cygnets, capturing cries of distress, parental reassurance, and a reunion. The whistling swan differs in size and name, breeds in the Arctic, and its high flight and wariness aid survival on this continent.

Termite Death Zone and DDT Treatment Findings
A chemical curtain formed by DDT around wooden structures can protect for years. Government lab tests show five percent DDT in fuel oil applied at a quart per cubic foot of soil near the base remains effective for about five years, though duration is not precisely known. The method was used in 1943 around an Orlando laboratory and continued to kill termites.
