 and (3) to reconnoitering a broadly interesting and useful field of algebra. This means 

 postponing the scientific and purely logical aspects of algebra to a later period. 



Geometric Exercises for Algebraic Solution, for Secondary Schools

This book supplies means for holding, through the second year geometr}' course, the 

 ground made in algebra during the first year. By the use of geometric problems to be 

 algebraically solved the course sen'es the three-fold purpose (i) of keeping algebraic pro* 

 cedure in continual use, (2) of holding the unity of the geometrical course intact, and (3) of 

 pointing out many connecting by-ways and overlapping districts of the two domains of ele- 

 mentary mathematics.
