Probably a compromise between these two extremes would 

 be the better course, viz., a continuous propaganda to induce 

 physicians to limit the range of medicaments employed by 

 them, and also a liberalizing of the pharmacopoeial list so as 

 to include a wider range of remedial preparations. The Phar- 

 macopoeia already contains a list of formulas which are con- 

 fessedly imitations of, or substitutes for, certain proprietary 

 compositions of established reputation, and there is no reason 

 why the list of official formulas should not be extended to cover 

 all of the usual daily wants of the physician. 



The drainage engineer who should undertake to regulate 

 water-flow without regard to the natural drainage channels 

 established by topography would certainly meet with disaster. 

 Those who would regulate the flow of social and professional 

 affairs must likewise take into account known tendencies and 

 dispositions. 



If proprietary remedies did not present certain advantages 

 for the use of physicians the latter would not use them. If the 

 official list of remedies does not afford the physician a suffi- 

 ciently wide range of choice, or if they are lacking in elegance 

 or uniformity as commonly dispensed, we cannot blame him for 

 resorting to proprietary preparations which are especially de- 

 vised with a view of meeting his desires and satisfying his con- 

 venience. 



THE COMPOSITION AND ORIGIN OF MONK'S 



MOUND 



A. R. Crook, State Museum, Springfield 



Six miles east of St. Louis, in the rich bottom lands of the 

 Mississippi Valley, are a series of about seventy mounds called 

 the Cahokia Mounds. They vary in height from a few feet to 

 ninety feet and in horizontal dimensions from fifteen to one 

 thousand feet. They are scattered for more than one mile in 

 an east to west direction. The largest of them, known as 

 Monk's Mound, is ninety feet in height, seven hundred feet in 

 breadth and one thousand feet in length.
