crop yields a11d good-sized l1erds were more profitable than
s111all o11es. Pasture data sl1owed tl1at XVll€I'G pastures ear-

A scheme of CO111bl11GCl. planting of cor11 a11d soy bea11s is
of much interest to live-stock 111e11. A year’s 1·esults sl1ow
that soy beans, pla11ted witl1 the hill of cor11 or between hills,
do 11ot reduce tl1e yield of COY11 to a11y exte11t, 2`t11(l. do increase
the total value of tl1e grain produced per acre. Tl1e mixture
111akes a well-balanced ration.
A study of tl1e n1etabolisn1 of the cl1ickc11 a11d otl1er ani-
1112llS by Dr. Buckner is yielding interesting results. Calcium,
magnesiun1 a11d phosphorus, 1l1l11G1‘E1l ele111e11ts, are essential
to tl1e growth a11d normal devel0p111e11t of an animal, as typi-
fied by the rat Etlld cl1ick. Tl1e total or partial absence of
normal quantities of these elements iminediately affects the
norinal develop111e11t a11d growth. This investigation is fun-
da111e11tal to 311 understanding of wl1at occurs during growth [
and development to lllillllflty and i11dieates the possibility of
tl1e utilization of tl1ese elements i11 CCFl2ll11 i11sta11ces of 111al- _
nutrition.
