 nels which did not reach the earth. Mr. Dietz said that after the funnel 

 left the city there was another one southeast of it which was white instead

 Mr. Mathiesen, who prepared the map of the storm's path through Coding- 

 ton County (Fig. 2), said that there were two funnels and his map 

 shows the path of the second one, which, peculiarly, seems to have crossed 

 the path of the main storm. He was at his farm about three miles east 

 of Watertown and witnessed the storm as it passed by.

 points where the greatest destruction occurred. The small arrows indi- 

 cate the direction in which objects moved as assumed from their position 

 before and after the storm. The writer is aware of the fact that in cases 

 where objects were moved for some distance the arrows may not indicate 

 the direction of movement, but where houses were only moved slightly
