Buckley—Sleet Storm in the Ozark Region of Missouri . 309 
occurred in another part of the Ozark region farther north, 
wrecked the trees very much as did the one here referred to. 
This storm reached the Missouri river bottoms, breaking and 
bending to the ground the slender willows of the “bottoms.” 
A year following the storm these willows still remain bent like 
bows. They are bent in every conceivable direction, which 
would not be the case were it the result of a wind storm. 
Referring to the sleet storm of 1STov ember 19th-20th, 1906, 
the destruction occasioned thereby is well illustrated by the 
accompanying figures. Figure 3 is a view of a portion of the 
campus of the Missouri School of Mines as it appeared during 
the summer prior to the sleet storm. Figure 4 is a view of 
about the same portion of the campus just after the storm. 
These illustrate very clearly the havoc wrought the shade tree? 
by the sleet. Figures 5, 6, 7, 8, 9, 10, 11 and 12 were taken 
in various parts of the city of Rolla and further illustrate the 
destruction accomplished by the storm. 
It ,may be interesting to note that the temperature during 
the storm was almost constantly at one degree below freezing. 
Measurements were made, in the offices of the Bureau of Geol¬ 
ogy and Mines, by Mr. IT. A. Buehler, showing the weight of 
ice carried by some of the branches, wires, etc. A twig 12 
inches long with ice attached weighed 8 ounces. The twig 
after removing the ice, weighed % ounce. A branching twig 
15 inches long carried 18 ounces of ice. 
The coating of ice which formed on twigs, branches and 
wires was from 1 to l 1 /^ inches in diameter. It was estimated 
that each wire strung between telegraph poles 200 feet apart 
carried 100 pounds of ice and that 12 wires, carried a half a 
ton. These estimates are probably under rather than over the 
actual weight.
