 cisely same time as yesterday." Algona — "For three days have had 

 thunder-storms nearly all time after noon until daylight of next morn- 

 ing. All have passed to northeast." Cresco — "The above storms 

 seem to be a continuation of those of yesterday." Albia — "Mag- 

 netic needle 15' east at 8:00 a. m., and 22' east at 9:00 a. m." 

 Mt. Pleasant — "Moderate lightning and thunder. Lightning struck

On the 18th, Iowa was in the southeast quadrant of a "low" area 

 over Eastern Dakota and Western Minnesota. This is one of our 

 typical "squalls." Hinrichs reports it as "extending over Northern 

 and Eastern Iowa, locally, with heavy rain, thunder, and lightning." 

 Unfortunately, the time records do not admit of a "portrait" of this 

 storm. A few notes are here given. The day was the hottest of the 

 month. At Brush Creek, the temperature at noon was 102 '. Clinton 

 — "Wind gusty, carrying clouds of dust high into the air. Rain began 

 in a dash, and the wind abated soon after rainfall commenced." 

 Cresco — "Storm clouds passing around all the afternoon; some, with 

 much heavier rain than we had, passed both north and south of us." 

 Algona — "Lightning struck frequently from clouds to earth. Four dis- 

 tinct thunder-storms to-day; all formed high up, and went to east. 

 All the thunder-storms thus far in June, except that of to-day, were 

 formed near by, high up, and seemed to gather force as they moved 

 northeast; 'pocket clouds,' at 6:00 p. m., passing from southwest to 

 northeast." Ft. Dodge — "Clouds look threatening; pass away with 

 high wind; blue sky at 4:00 p. m." Concord — "Lightning in every 

 point, except, perhaps, southwest; a continuous storm from west and 

 southwest to northwest, north, northeast, east, and southeast; Thomas 

 Jakonbek killed by lightning four miles north of here, at 5 :oo p. m." 

 New Providence — " Hail, north and nothwest, breaking small limbs from 

 trees." Orange City — "Team killed, and driver (William Rombough, 

 of Hull) stunned by lightning." Davenport — "About noon, the storm- 

 line of stratus clouds was seen in the northwest, which slowly advanced 

 until the storm broke at 5 : 45 p. m. ; wind furious and broken, but 

 storm did not seem able to pass over to the south, where a strip of blue
