Whether the funnel is yelled reeeipt raip or not, it is ordinarily so black Ye D pu Hsst as it approaches, it appears " r iro1 nnn of dense darkness, narrowest ' 1..i plrecs 7. the earth, with light breaking on 4u'p ''aa .sber side of it. The most marked

 tian The tunnels have a. rotary motion list, from right to left, and this motion is
 not due to electrical action, but to ae-
 celeration of conflicting air currents
 Lieut. Finley shows that the lightning 9iasl T ol supposed to be in the funnel is really visa in adjacent thunder clouds. The broken CTS and withered buds, bruised by the ac- LIE 2 ton of the air, evaporated by tie ons sun after the tornado, causing the sti- foliage to look scared. giving rise to ahs the error that the tornado manifests
 burning electrical power. It has been er- demonstrated by study of wreekage ds. that as the funnel leaves the earth and rises into the air it's force slightly di-
 minishes, and that this bounding mo- ss ton causes the funnel to spare one 'n. building and dcmolish another. The :, funnel, with it's small end 10 the earth, fs spins like a top, moving along at an le average rate of about 40 miles an hour, a. but the velocity of the spin is incalea-
 lable. It is like the motion of air ina ,f peled by an explosion.
 Tomatoes generally occur between

 day. have heard of only two in- , stances in which the tornado occurred
 between midnight and morning-one
 at Hohol1us, N. J., and another i'll south
 ern Michigan, which caused slight loss
 oflife. Since these are only two in about
 2,0oo cases, the danger from tornadoes
 at night is so small that it need not be
