	I wrote an article for the AIS Bulletin years ago called "Border
Patrol" in which the above subject was discussed.

	Proportion is the the key to introducing a BB that is a
segregate from tall breeding.

	Several years ago, Allan Ensminger offered a border collection,
and if TULARE was the standard for judging BB's years ago, CALICO KID,
BRIGHTEN THE CORNER, CALORIFIC, AND YO (the cultivars in that collection
that Allan offered) are hallmarks today for judging the class.

	The flowers are proportionally smaller and the stalks tinner and
under 27" in height.

	A TB sized flower on an 18" stalk should stand out as odd and
inappropriate for the class.
