1Maximum and minimum temperatures at stations in the United States are from self- 
registering maximum and minimum thermometers. The means have been deduced from 
observations three times daily—7 a. m.,3 and 11 p. m., seventy-fifth meridian time. Precipita- 
tion includes rain and melted snow. : 
? Mean of observations three times daily except from July to December, 1888, inclusive, when 
but two observations were made each day.
