When considering the amount of palseontological work that 

 has been done in the State of Wisconsin, this is a very good rep- 

 resentation. There is still, however, much work that remains to 

 be done and there is a fine field for the local collector in almost 

 all parts of the state as no matter how closely a locality may be 

 worked over there always remain new species to be found when 

 least expected ; and from the collections now made and those that 

 may be made in the future past experience shows that in the hands 

 of the specialist the collector can derive much credit.
