86 KANSAS CITY REVIEW OF SCIENCE. 



especially while the tornado cloud was passing a given point ? If so, send me 

 his address or give the result of the observations. 



73. Try and give an estimate of what you consider the wind's velocity with- 

 in the central whirl of the tornado cloud and also the data upon which you base 

 this estimate. 



74. In the destruction of your buildings, did you notice anything in the 

 disposition of the debris after the tornado cloud passed that would indicate the 

 effect of an explosion, as for example, the sides and the ends of a building being 

 thrown outward and the roof carried off or let down upon the floor? 



75. In the passage of the tornado cloud over a pond, lake, or river, care- 

 fully describe every particular in the disturbance of the water ; how high into the 

 air any portion of it was carried ; if any fish, shells, stones or the like were car- 

 ried out and in what direction. Also state the exact position of the person or 

 persons who witnessed the scene. 



76. Was mud, bits of leaves, straw, grass or the like thrown against your 

 buildings? If so, state on what particular portion or portions, and whether ap- 

 parently thrown thereon with great force. If thrown upon the bodies of persons 

 or animals carefully state the circumstances. 



77. Sketches of clouds, of peculiar destructive effects, of hailstones, of any- 

 thing that will illustrate any distinguishing feature of the storm's violence are 

 very desirable. 



78. If you recall the occurrence, in times past, of any violent hailstorm in 

 your State, give the place, year, month, day of month, hour of day, direction of 

 of the storm, maximum and minimum width of path in rods or miles, size and 

 shape of hailstones, and a narration of the destructive effects. 



79. If you recall the occurrence, in times past, of any other tornado in your 

 State, give year, month, day of month, hour of day, the direction of the course 

 of the path of destruction as pursued by the tornado cloud, its length in miles, 

 average width of destructive path in yards or rods, maximum width, minimum 

 width, and if possible, the hour of beginning and hour of disappearing of the 

 tornado cloud. 



My report upon the tornadoes of 1882 will be published in book form and 

 can be obtained free of cost by applying through your Congressman, to W. B. 

 Hazen, Brig, and Bvt Major General, Chief Signal Officer, U. S. A., Washing- 

 Ion, D. C. My report upon the tornadoes of 1879, now ready in book form, as 

 also another publication, "Facts about Tornadoes," the latter of which contains 

 practical rules showing how to avoid the violence of tornadoes, can be obtained 

 in the same manner. 



My office will be at Kansas City for the next two or three months, where I 

 shall hope to see or hear from all persons interested in this subject.
