to illustrate this influence. With the exception of the Iowa points, the 

 stations are arranged in contrasting pairs, the odd-numbered stations 

 being located close to considerable bodies of water. In practically every 

 case these stations show higher January means and lower July means 

 than the respective stations with which they are contrasted. In every 

 case the April temperature for the inland station is higher and November 

 temperature lower than at the points near water. The Iowa stations of 

 approximately the same latitude as the majority of the more eastern 

 points show intensification in all these differences. Milwaukee and 

 Grand Haven, at almost opposite points on Lake Michigan, show the 

 influence of the lake on the prevailing winds blowing over it. That the 

 retardation for these stations is generally somewhat greater in the spring 

 than in the fall is shown by Table 6.
