The temperature for the three days during which this part of 

 the experiment was continued remained at all times below o C. 

 There was quite a high wind during a greater part of the time 

 and the effect of wind upon the evaporation may easily be seen. 

 The amount of evaporation increased considerably with an 

 increase of wind velocity. 



The snow was put into the wire receiver very lightly so as not 

 to diminish the size of the pores or space between the crystals. 



The wind caused the index to vibrate up and down so that it 

 was necessary to make the readings by the method of vibrations. 

 This is why the distance is carried out to the third decimal place. 



The iron wire made a very delicate means of detecting the 

 loss in weight. The length of the wire was about three feet so 

 that a very small decrease in weight made a large difference in 

 the height of the index.
