Ah, spring! Time to get out and enjoy the outdoors. A good time, also, to plant trees. So the Arbor Day Foundation has a deal for you. Each person who joins the foundation in March will receive 10 free white pine trees, which will be shipped postpaid at the right time for planting between March 1 and May 31, depending on your locale. Members also receive a subscription to Arbor Day, a bimonthly publication, and a copy of "The Tree Book," filled with information about tree-planting and care.

To join, send a $10 contribution to Ten Free White Pine Trees, Arbor Day Foundation, 100 Arbor Ave., Nebraska City, NE 68410 by March 31. Join online or get more information at www.arborday.org.
