562 HISTORY OF PASADENA. 



At some time the waters poured down through Fair Oaks Avenue and found 

 their way into the San Gabriel river. 



[Note. — This corresponds almost perfectly with the three ancient ter- 

 race lakes which I had described in explaining the great antiquity of the 

 stone implements found buried so deep on Reservoir Hill, which was before 

 I knew anything about Judge Eaton's views on this matter. I give him 

 credit for being the first to discern the true character and relative positions 

 of these several water beds. — Ed.] 



Later on, and after they began to break away through and down the 

 Arroyo, they were arrested by the bluff near Lincoln Park, which at that 

 time probably extended to Garvanza and connected with the range of hills 

 on the San Rafael ranch. [Note. — This is the same that I had described 

 as a fourth terrace lake. — Ed.] The waters turned through South Pasa- 

 dena, and thence in a southeasterly direction to the bed of the San Gabriel 

 river. But finally breaking through this last barrier they coursed on toward 

 the Los Angeles river without meeting with further obstruction. 



A phenomenon has occurred within the life of Pasadena with the water 

 supply of the springs in the Arroyo Seco that goes far in my mind toward 

 corroborating the theory of there being two or three distinct and separate 

 basins. Ten or fifteen years ago my son Fred, civil engineer, and I were 

 passing up the Arroyo, and noted the flow at the Sheep Corral springs. He 

 estimated it at twenty-two inches — certainly not to exceed twenty-four. At 

 a later period, Mr. Schuyler, the noted hydraulic engineer, was employed to 

 measure the waters from the various springs in the Arroyo. Devil's Gate he 

 gave as ninety-six inches, and two inches waste, making ninety-eight inches 

 there. Under his direction, Mr. McQuilling, the zanjero of the Pasadena 

 Water Co., measured the Sheep Corral springs, and from his data Schuyler 

 gave as an approximate of the flow, fiftj^ inches. In speaking of inches, 

 miner's inches are meant, one of which equals about 13,000 gallons per day 

 of twenty-four hours. Last year I visited the springs with Mr. P. M. 

 Green, and at that time, midsummer, there was not less than 150 inches of 

 water there ; and that after the water had been picked up and diverted into 

 the pipes at Devil's Gate. Now comes the question, what had brought 

 about this wonderful increase ? My theory is that the water had been 

 carried over the divide between the two basins in pipes and deposited in the 

 lower basin for a term of years until the ground had become thoroughly 

 saturated, thus augmenting the supply ; consequenth^ there was an in- 

 creased flow through the natural drain at the Sheep Corral springs. What 

 strengthened my belief is that the springs above have not shown a correspond- 

 ing increase, though their average discharge has increased of late years. 

 That I attribute to the fact that the waters of all the little streams from the 

 mountains, which formerly were principally lost by evaporation, have been 

 gathered and poured onto the lands covering the upper basin until it has be- 

 come saturated, and now add their volume to the supply of that basin. 

 This is the only theory that I can evolve from the circumstances, since the 

 water shed has not been extended, and the average annual rainfall has 

 shown no material increase during the past few j^ears. 



EXPLANATION CHANGE OF CLIMATE. 



This increased flow from the springs is a very interesting fact, yet very 

 simple of explanation, and is connected with the change of climate which is
