present secretary is at Hartford, Conn. The American 

 Trotting Association was organized in 1887, and has head- 

 quarters in Chicago. The American Trotting Register 

 appeared in 1868, with J. H. Wallace as publisher. The 

 first volume contained some 3000 entries ; 62,000 stallions 

 and about 250,000 mares have been registered to date. 

 Wallace also established the Yearbook, now in its thirtieth 

 volume. The Register, the Yearbook, and Wallace's 

 Monthly were disposed of by Mr. Wallace to the American 

 Trotting Register Association, in 1891, and the latter now 

 publishes the Register and the Yearbook. As has been 

 said, a League of Amateur Driving Clubs has been formed, 

 with headquarters in Boston. This league publishes a 

 yearbook, giving a summary of matinee races and the 

 time made. The first volume includes the races of 1901-2.
