Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

These incoherent words threw the first glimpse of light on the meaning of her distress and penitence. I doubt if the best woman in Christendom would so reproach and abase herself, if convicted of even a worse sin than the secret use of those stimulants for which the "charny" is a Martial equivalent. No Martialist would dream of poisoning his blood and besotting his brain with alcohol in any form. But their opiates affect a race addicted to physical repose, to sensuous enjoyment rather than to sensual excitement, and to lucid intellectual contemplation, with a sense of serene delight as supremely delicious to their temperament as the dreamy illusions of haschisch to the Turk, the fierce frenzy of bhang to the Malay, or the wild excitement of brandy or Geneva to the races of Northern Europe. But as with the luxury of intoxication in Europe, so in Mars indulgence in these drugs, freely permitted to the one sex, is strictly forbidden by opinion and domestic rule to the other. A lady discovered in the use of "charny" is as deeply disgraced as an European matron detected in the secret enjoyment of spirits and cigars; and her lord and master takes care to render her sufficiently conscious of her fault.

A West Tennessee nonprofit organization will use a $300,000 federal grant to hire an attorney and a Spanish-speaking paralegal to help provide legal assistance to domestic violence victims. The U.S. Department of Justice two-year grant will begin Oct. 1, which is the start of domestic violence awareness month. U.S. Rep. John Tanner announced Monday that the grant was awarded to West Tennessee Legal Services of Jackson. The organization provides legal assistance and advocacy in 17 counties. "This award will offer assistance as we look for whatever ways possible to stop domestic violence and help the women, men and children who are victims of abuse," Tanner said in a news statement. The organization doesn't have a staff member who speaks Spanish and the need is increasing with growing Hispanic populations, said the organization's executive director Steven Xanthopoulos. He estimated the money will help handle at least another 180 cases next year. The group closes about 2,500 cases a year. The money was timed well because the legal group had recently lost about $120,000 in grant money due to a decrease in the poverty population in West Tennessee in Census 2000, Xanthopoulos said. "The drop in poverty is a good thing, but there is still a great need out there," he said. "So this was a very good thing." Having legal representation at divorce and child custody hearings is important in helping victims leave abusive and sometimes dangerous situations, said Margaret Cole, executive director of Wo/Men's Resource and Rape Assistance Program in Jackson. Her organization and Northwest Safeline are partners in the grant. Northwest Safeline, based in Dyersburg, is a family violence intervention project that serves Dyer, Obion, Lake and Crockett counties.
