sometimes when i rec climb with new climbers i will use a pulley. i figure the less energy they use the more they will enjoy the climb. how do you install the pulley from the ground?

Get your line over - call it rope A - and get the pulley and carabiner attatched to the working end, put your climbing rope (rope B) through the pulley, haul it all up to the highest point that your rope's at (hopefully a nice strong crotch) and hitch the running end of the anchor rope A around the bottom of the trunk.
Then, attach your split tail to the running end of Rope B, clip in to the working end and Bob's yer uncle!
Clear?
