614 KANSAS CITY REVIEW OF SCIENCE. 



workmanship, of unfair and dishonorable competition, of jealousies and of pro- 

 fessional envy and backbiting, can be traced directly to short and hurried appren- 

 ticeship. A business or profession which shortens its course of study of appren- 

 ticeships, which eagerly seeks every youth for its pupil, and opens wide its por- 

 tals of instruction, offering every inducement which appeals to indigence, igno- 

 rance and to mental inactivity and stupidity, is not worth having, and is alike dis- 

 graceful and dishonorable to the recipient and to the donor. Again, gentlemen, 

 I say, make your standard high, access to your ranks difficult, the period of ap- 

 prenticeship and of instruction long and exacting, and do not fall in with the 

 popular idea of license instead of liberty, which accords to any man the right to 

 follow any profession or carry on any business, however intimately or delicately 

 associated with the public welfare, without a previous training and instruction for 

 intelligently and skillfully discharging its obligations. Permit me to say, in con- 

 clusion, that for reasons which are now manifest, I ought not, perhaps, have 

 acceded to your invitation to address you. My official duties during the past four 

 years have been so numerous and exacting that I have had no time for literary 

 composition and for preparing a lecture, such as would do justice to you or my- 

 self. But I could not resist the opportunity of co-operating with you in your first 

 efforts in this city. And, gentlemen, whatever shall be my future in this city, in 

 office or out, you may always consider me at your side, battling with you for 

 your rights as sanitarians and as public benefactors. 



GEOLOGY. 



DESCRIPTION OF MARBLE CAVE, MISSOURI. 



FURNISHED BY CAPT. J. B. EMERY. 



Roark Mountain, in Stone county, Missouri, is the highest point of the 

 Ozark range within a radius of twenty-five miles. It is surrounded by the head 

 waters of Roark Creek, Big and Little Indian Creeks, Fall Creek, and Jacob's 

 Branch, all flowing in different directions. To the south is White River, towards 

 which the mountain slopes ; to the north James River. The first is about three, 

 the other six miles from the top of the mountain. 



That top is a strip of table land, about one mile long and from an eighth to a 

 quarter of a mile in width ; one thousand feet above the level of White River. A 

 magnificent view presents itself from that point. The eye sweeps over range 

 after range of mountains, heavily timbered with oak, black-walnut, cedar and 

 pine, valleys with streams meandering through them. A bracing, invigorating 

 atmosphere. Abundance of game. Springs of pure water, and medicinal springs,
