THE DEVELOPMENT OF AMERICAN BAC* 

 TERIOLOGY. 1 



BY H. L. RUSSELL, MADISON, WISCONSIN. 



Those of us who hail from the middle west, 

 where the cross-currents of a mixed civiliza- 

 tion have mingled many ethnic strains, have 

 perhaps less appreciation of the pride of ances- 

 try than those whose lot it has been to dwell in 

 the shadow of the old family rooftree. Not 

 often does the genealogical fever strike the 

 pioneer or his immediate successors. Gener- 

 ally he is too busy in hewing out a home for 

 himself and family to bother with historical 

 studies. It is only after he strikes it rich that 

 he feels the need of a coat of arms, or his wife 

 seeks admission to the Society of Colonial 

 Dames. In large measure too are historical 

 retrospects likely to be disregarded by those of 

 us who have turned our attention to some of 

 the newer lines of study that are now possible. 



The student of botany or chemistry or phy- 

 sics has a long and glorious past in which he 

 can revel. If he attempts to prepare a chair- 

 man's address, he may go back in the history
