With Straus trophy standings riding on every stroke, six House crews will race off the final round of the crew competition this afternoon at 5:30 p.m. on the Basin course. The eights will race upstream over the mile distance, finishing near the M.I.T. boathouse...
...main stages planned: 1) the blasting out of a mile-long channel to detour the Nile around the main dam; at one point the channel will go underground through six rock tunnels (see map) and activate the turbines of a power station; 2 ) the construction of an upstream cofferdam to steer the Nile into its new bed. and of a second cofferdam downstream so that the river will not seep back into the dam site after its detour; 3) the building of the main dam itself, which cannot begin until the channel is cut and cofferdams are in place, supposedly...
First countermeasure tried by the fishes' human allies was electrical barriers across stream mouths to keep mature lampreys from swimming upstream to spawn. But many streams were already packed with growing larvae from lamprey eggs, so the U.S. Fish and Wildlife Service and the Canadian Department of Fisheries decid ed to destroy the larvae themselves. In search of a selective lamprey-larva poison, they tried more than 6,000 different chemicals on jars containing two lamprey lar vae, two bluegill fingerlings and two small rainbow trout. Some chemicals killed nothing; some killed both larvae and fish. Some killed...
Confident Service. TFM was first used in 1958 on lamprey-spawning streams that flow into Lake Superior, and by last spring the tide had turned against the slimy invaders. The number caught in traps as they tried to swim upstream fell to 12% of the 1961 catch. The adults are apparently dying off and are not being replaced by adolescent larvae...
...down and read the annual appeal for contributions to the Harvard Fund. It might contain a richly allusive essay on how Thoreau would have viewed the college hierarchy, or some gentle musings on the anti-Harvard attitude of Harvard's Henry Adams, or even reflections on the upstream migration of the alewives, persistent saltwater fish that find their way to Massachusetts streams each spring. These unlikely enclosures come from a man with an unlikely blend of talents: David McCord-poet, essayist and professional fund raiser-who retires this week after 37 years as executive director of the Harvard Fund...
