Here's a clip off www.hawgslimited.com under the "Best Directions" link:

SCENT MARK WITH GLAND: Use BF-FGAND anytime to get a response. You should scent mark on licking branches, decoys, vegetation around your stand, rubs, or even create mock-rubs. The more of this gland scent you use, the more it generates a response from any deer. By a deer's instinctive nature they simply need to try and identify the new deer leaving all this fresh gland scent in the area. They should keep returning to your scent marking and will actually begin looking for you as a new deer intruder.
