Editorial. 



It is always a pleasure to note a graceful expression of appre- 

 ciation of long and faithful endeavor to promote our science — doubly 

 so when this service has been given in a singularly quiet and modest 

 way, without any apparent realization of its true merits. 



At a recent alumni dinner of the State University of Iowa, the 

 former students of Professor Samuel Calvin, to the number of over 

 two thousand, united in the commemoration of the completion of his 

 thirtieth year as professor in that institution. The recognition took 

 the form of a costly silver loving-cup, designed especially for the 

 purpose of symbolizing the scientific achievements of the recipient. 

 The cup is a classic Greek vase, sixteen inches in height, and stands 

 on a base of serpentine five inches high. It is adorned with casts 

 taken directly from fossils, with a drainage map of Iowa, with crossed 

 geological hammers, a microscope, and the more conventional spray 

 of laurel, owl of wisdom, and torch of learning — all in relief. One 

 side bears an appropriate inscription in raised letters. 



Professor Calvin was elected to the chair of natural history in 

 Iowa's university thirty years ago. The chair has since been sub- 

 divided into four distinct departments. Professor Calvin retaining the 

 department of geology. As well known to the profession, he has been 

 state geologist of Iowa during the last twelve years, and an admirable 

 series of reports is appearing under his administration.
