A tick will attach itself to its host by inserting its chelicerae (cutting mandibles) and hypostome (feeding tube) into the skin. The hypostome is covered with recurved teeth and serves as a hammer.Wikipedia on ticks…
John M. Greer discusses magical thinking and the BP spew. He answers a question that I, former repair plumber, have been asking. The pressure of the oil/gas, 13,000psi. One other pressure question, water pressure at 5,000 feet?
Meanwhile, pressure in the well continued to rise Monday, albeit slowly, reaching 6,811 pounds per square inch, Allen said in the late afternoon. He said the pressure was rising about one pound per hour.
This, too, has triggered debate among BP and U.S. officials, who had expected the pressure to hit 8,000 psi and who thought that lower pressure readings would be a sign that oil and gas was leaking into rock formations through damaged well equipment. But because of the steady increases in pressure, BP and government scientists are wondering whether so much oil and gas had been spilled already that the pressure in the partly depleted reservoir has been reduced.–WaPo 7/20/10
Ride of Silence, Charlottesville, May 19
One of the goals of the clean water act was to ensure that surface waters would meet standards necessary for human sports and recreation by 1983. In Virginia we have been talking about the the value of state waters for awhile.
To the end that the people have clean air, pure water, and the use and enjoyment for creation of adequate public lands, waters and other natural resources, it shall be the policy of the Commonwealth to conserve, develop and utilize its natural resources, its public lands and its historic sites and buildings.
Further, it shall be the Commonwealth’s policy to protect its atmosphere, lands and waters from pollution, impairment or destruction for the benefit, enjoyment and general welfare of the people of the Commonwealth.–Constitution of Virginia, Article 11
Alex Epstein has written about canceling earth day. There is an idea. Hey Alex? How about going for a swim in Moore’s Creek?

Tulip trees on the west side of Monticello.
This is an old tree. There is evidence it was planted April 16, 1807. I have five tulip trees to plant this weekend. This tree is 22 feet in circumference, the trees I am planting are 3/4 of an inch in circumference.
This tree affected many lives. One was my neighbor Mike Van Yahres grandfather’s. (Visit Monticello’s podcast section and search poplar for that story)
The tree was removed. Profound health issues. I am pleased that the grounds people are leaving the stump in place for awhile. It is a memorial.
See Patterson Clark’s excellent article in the Washington Post about tulip trees.
