404 Miscellanies. 
The climate of this part of the state must be affected by such 
great bodies of water. As the water is cooled in winter, it must 
take a considerable time for the temperature to rise to that of he 
air, and hence the winter must be prolonged a little, and the spring 
be retarded, and in autumn, the water must be throwing off its ca- 
loric to the atmosphere, and retard to some extent the approach of 
winter. The frequent direction of the wind towards the lake, while 
the upper air is moving in a different direction and often in a nearly 
opposite course, shows the influence of the cooler waters of the lake 
in summer. 
At my request Mr. William McAnslan, the engineer of the steam- 
boat Traveler, made the following observations upon the temperature 
of the lake. ‘The observations began May 5th, 1837.
