degrees 4 2-l0 minutes W., and Will
cut this meridian at right angles. If
continued further il will cross the
original meridian of rs degrees w. I'm
latitude 80 degrees So minutes AZ sec

@. What weight in cork is required
to support a 150-pound man in water?
n. K D.
A. The Bureau of Standards says
the amount of cork used to supper
body in water depends entirely upon
the body. Many things must be
taken into consideration, such as the
bones and flesh. Nine out of ten
people float naturally because the
body is supposed 10 be as light a.
water. In general, If the body is as
light as water and 25 pounds of the
$50 pounds is out of water, such a.
the head, neck, shoulders and arms,
it would take pounds and 10 ounces
of cork to support the body.

Clayton also mentions this myth in a
letter to the Royal Society OF London

port it is asserted that there lived
in the Carolinas a snake whose tail
was poisoned horn or spike. This
account refers to the horn or sting

of this snake tdpers TO fine point
having the appearance of q horn or
spike, but is quite incapable Of pierr-
