TORNADO STUDIES FOR 1882. 83 



26. Give the direction of the wind while the tornado cloud was approach- 

 ing, while the tornado cloud was passing and after the tornado cloud passed. 



27. The direction of the wind during the fore part of the day and up to the 

 time of the first threatening appearance in the heavens. 



28. The prevailing direction of the wind at this season of the year. 



29. In asking for the direction of wind, I mean direction of motion of the 

 surrounding air currents, independent of the course or motion of the tornado 

 cloud. 



30. Any hail, and did it fall before or after (how long) the tornado cloud 

 passed ? 



31. Were the hailstones large or small, of peculiar shape, and few or many 

 in number ? Give exact size and weight of the largest. 



32. On which side of the tornado's path (to the N or to the S.) did the 

 hailstones appear to fall in the greatest quantity ? 



33. Did you examine the interior of any of the hailstones, and if so, how 

 were they formed and what did they contain ? 



34. If hail fell at intervals through the day, state the times of beginning and 

 ending of each precipitation separately, together with the direction of the wind at 

 each occurrence. 



35. Any rain, and did it fall before or after (how lung) the tornado cloud 

 passed ? 



36. On which side of the tornado's path (to the N. or to the S.) was the 

 rainfall the heaviest ? 



37. Any peculiarity in the size or shape of the rain-drops, or in the quanti- 

 ty which fell ? 



38. If rain fell at intervals through the day, state the times of beginning 

 and ending of each precipitation separately, together with the direction of the 

 wind at each occurrence. 



39. What time of day did threatening appearances commence, in what por- 

 tion of the horizon,, and at what time were they the most decided? 



40. Describe the character and motion of the surrounding clouds before, 

 during and after the tornado cloud passed. 



41. Give the general atmospheric conditions of temperature, wind direc- 

 tion, humidity and clouds, for from ten to fifteen days previous to the occurrence 

 of the tornado and from three to five days thereafter. 



42 . Give the time of day at which the light or dark irregular clouds sur- 

 rounding the tornado cloud were in the greatest confusion, and describe the 

 scene. 



43. Describe any particular change or motion in the tornado cloud and the 

 successive stages of development during the time of observation. 



44. Give the direction of the whirl of the tornado cloud, as against or with 

 the hands of a watch.
