IRRIGATION} 



Science has been defined as the medium 

 through which the knowledge of the few 

 can be rendered available to the many ; and 

 among the first to avail himself of this 

 knowledge is the engineer. He has created 

 a young science, the offspring, as it were, 

 of the older sciences, for without them 

 engineering could have no existence. 



The astronomer, gazing through long ages 

 at the heavens and laying down the courses 

 of the stars, has taught the engineer where 

 to find his place on the earth's surface. 



The geologist has taught him where he 

 may find the stones and the minerals which 

 he requires, where he may count on firm 

 rock beneath the soil to build on, wh^re he 

 may be certain he will find none. 



The chemist has taught him of the subtle 

 gases and fluids which fill all space, and 

 has shown him how they may be trans- 

 formed and transfused for his purposes. 



The botanist has taught him the proper- 

 ties of all trees and plants, ' from the cedar 

 tree that is in Lebanon even unto the hys- 

 sop that springeth out of the wall. ' 



And all this knowledge would be as noth- 

 ing to the engineer had he not reaped the 

 fruits of that most severe of all pure and 

 noble sciences— the science of numbers and 

 dimensions, of lines and curves and spaces, 

 of surfaces and solids— the science of 

 mathematics. 



Were I to attempt in the course of a 

 single address to touch on all the many
