27. Give the direction of the course pursued by the tornado cloud along its 

 path of destruction in your locality, as for example : N 70° E; E 30° N or E 20° 

 S; etc., etc. 



28. Give the maximum and minimum width, in yards or rods, of the path 

 of destruction in your vicinity, and state, if you can, whether in examining that 

 path, it was found that on the S. side of the centre the sweep of destruction was 

 broader and more irregular than on the N. side, or if any other difference existed 

 between the two sides. 



29. If you, or any of your neighbors, have meteorological instruments, give 

 the readings of the thermometer and barometer, direction of the wind and the 

 hour of observation, for two days before, the day of the storm, and for two days 

 thereafter, viz : on the 



30. If you recall the occurrence, m tmies past, ot 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, maximi m width, minimum 

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

 nado cloud. 



When I ask for direction of wind, I mean direction of motion of the sur- 

 rounding air currents, independent of the course or motion of the tornado cloud. 



When time of day is asked, give the same in hours and minutes, and state 

 whether it is local or railroad time, and by what standard, viz : Chicago, Detroit, 

 Columbus, St. Louis, etc., etc. 



In giving your distance from the center of the path of destruction, indicate 

 the same in miles and parts of miles or rods, stating the amount in northing and 

 easting,, northing and westing, southing and easting, or southing and westing, 

 estimated along section or township lines. 



If not individually prepared to answer any or all of the above questions, 

 please call to your aid such persons as may, in your judgment, be able to render 

 you assistance. 



If possible, try to represent the tornado cloud by a rough sketch, as also the 

 dark and irregular clouds surrounding it. 



In describing the path of destruction, be careful to note where the tornado 

 cloud left the ground, where it again descended, the length of the interval and 

 the topography of the earth at the points of ascension and descension. 



Send any newspaper article concerning the storm which you may have or 

 can obtain without inconvenience. 



Give name and address of any one in your State who is in the habit of keep- 

 ing a meteorological record. 



If possible, try and secure the coSperation of some intelligent person, who, 

 at the time of its occurrence, was situated either in the path of the tornado or on 

 the outer edge of it, and who will be willing to furnish me a narrative o the result 

 of his observations.
