nitely surpass them in usefulness, for it will 

 water a thousand gardens and farms, and 

 will furnish light and power to dispel the 

 darkness and drudgery of farm and country 

 life. 



The water that is held in this upper res- 

 ervoir, together with the one now being 

 built out on the plain, will hold water 

 enough for twenty-five or thirty thousand 

 acres of land. 



A concrete conduit, 3 feet in diameter and 

 12 miles long, carries the water from the 

 upper reservoir down to a small regulating 

 reservoir, almost overlooking the power sta- 

 tion 1900 feet below. From this small reg- 

 ulating reservoir the water is carried in a 

 steel pipe 56 inches in diameter at the top 

 and 44 inches at the bottom to the power- 

 wheels 1845 feet below. This pipe is 1^ 

 inches thick at the bottom and % inch 

 thick at the top. The water pressure is 900 

 pounds to the square inch, and the water 

 strikes the buckets of the impvilse wheels 

 going at the rate of four miles a minute. 

 About 21,000 horse power can be generated 

 by this stream of water when running at 

 full capacity. Some idea may be gained of 

 the value of our mountain streams when it 

 is remembered that this power-plant does 

 not take all the available power in Boulder 

 Creek; and among the Rocky Mountains 

 there are thousands of streams with more 

 available power than this one.

A LAYING QUEEN UNDER THE BOTTOM- 

 BOARD. 



A Peculiar Case of Bees Refusing to Accept a 

 New Queen. 



BY DR. S. P. SCHROBDER. 



Mr. E. L. Dickerson, of Bakersfield, Cal., 

 had a colony of bees that persistently killed 

 its queens, p. 564, Sept. 1. I had a similar 

 experience two years ago. The colony had 

 foul brood, but was of medium strength, so 

 the 27th of May, 1908, I made an artificial 

 swarm by shaking the bees in an empty 

 hive in which I had placed but very narrow 

 starters. I examined the colony in five 

 days. The bees had built comb about four 

 inches wide in the six central frames; but 

 one-third, at least, if not more, was drone 

 comb. I did not find the queen, but thought 

 nothing of it, as the comb was so soft that 

 a thorough examination was impossible. 

 Ten days after the swarming I examined 

 again, and I found no young brood nor eggs, 

 nor the queen. I concluded that the queen 

 got killed during the shaking process; and 

 as I had several nuclei with young laying 

 queens I gave this shaken colony one, and 

 the bees ate her out in two days, only to 

 ball and kill her immediately. I gave them 

 another laying queen and waited four days 

 before I liberated her, after first thoroughly 

 smoking the colony. That queen also lay
