Forty-sixth Annual Meeting. 17 



S. A. Deel: There are nine farms, but only one that would be at all 

 dangerous because of drainage. 



President Smith: I believe that the arrangement will fail after a 

 few years. It is not to be supposed that this 1300 acres is all going to 

 take up rain water and that all the rain water which it does take up will 

 run down to the filter wells. When the water that is already stored in 

 the sandstone is drawn out the supply is going to fail. 



W. A. Cook : Indications are that the land all drains through a point 

 where the filter galleries are located. 



President Smith: From other experiments in other places, notably in 

 California, such supplies always fail.

Paper No. 6, Phenomena Beautiful, by W. A. Cook, Baldwin. 



discussion. 



L. E. Sayre: The speaker has been able to see thirty miles in the dis- 

 tance. I should like to ask whether on shipboard, for example, where 

 you have no obstruction, is not the range of vision about fifteen miles? 

 Ordinarily it is impossible to see beyond fifteen miles. The distance in 

 this case is doubled. This is due, of course, to the refraction. 



F. E. Sibley: From the shore of Lake Erie I have been able to see a 

 town sixty miles away across the lake, the city appearing upside down. 



Miss MEEKEat: Asks as to time of year affecting the mirage. 



W. A. Cook : They may be seen at all times of the year. 



J. A. G. Shirk: In Texas and eastern New Mexico, in the middle of 

 the summer after a heavy rainfall when the low places are filled with 

 water, it is hard to tell the mirages from the real pools. 



: In Arizona I have seen lakes of water reflected from at least 



twenty-five to thirty miles from the Colorado river, or it may have been 

 a reflection from Salton Sea. In regard to this halo about the moon, I 

 made a diagram o: the phenomena as I saw it, only I think it was a halo 

 around the sun instead of the moon. There was a large halo, with 

 smaller halos on each side. 



Preisdent Smith: In regard to Salton Sea, I have also seen this 

 phenomenon. When we finally came to the sea itself it looked just as it 

 had looked in the mirage. We could not tell which was which until we 

 got within about one hundred feet of it.
