complain that their calling is not properly appreciated, a complaint which 

 will diminish to the extent that every grade of teaching is adapted to the 

 public wants. School teachers must therefore partake of the general im- 

 provement in education, and those who wish to qualify themselves by a 

 full or partial college course, should be supplied with a kind of normal 

 school instruction adapted to their wants. 



Farther our colleges must be able to supply to a greater extent than 

 formerly, the demand for civil and mining engineers, surveyors, architects, 

 draughtsmen, chemists, and observers in meteorology and magnetism, in ad- 

 dition to the necessary preliminary education required in the professions. 

 The great body of medical students have not had a proper preliminary ed- 

 ucation, although there is a great demand for properly educated physicians 

 in the army and navy. 



The United States government exhibits a strong disposition to encourage 

 the development of the natural history of its distant domain, and applica- 

 tions are made from time to time for competent investigators in geology, 

 zoology, and botany, to accompany the various exploring expeditions — and 

 it is a matter of difficulty to supply these places properly. 



Young men anxious to eniploy their leisure in extending the bounds of 

 knowlege, have ample opportunities to do so by investigating the history of 

 insects in their economical relations, with a view to counteract their depre- 

 dations ; and the success of such attempts must depend greatly upon having 

 a number of competent advisers distributed in various localities, to take 

 advantage of fitting opportunities as they occurs 



If I am asked the use of such studies, I answer, that living in an age of 

 less bodily but more mental activity than formerly, an activity, as I have

 sical and mental occupations, whether they involve utility, taste,- amuse- 

 ment, or caprice. Although the chief ends of labor are food^ clothing, and 

 a dwelling place, with the health which arises incidentally from bodily ex- 

 ercise, the food which to speak figuratively is "ruminated," is as important 

 if not as essential to a reasoning creature^ as that which is masticated. 



The athlete doe3 not develope his powers by fighting continually, but by 

 exercising his muscles in such a manner as to enable him to develope their 

 nascent powers that they may be used to the best advantage when required. 

 So natural science cultivates the observing faculties, fosters cautious habits, 

 and improves the judgment. As the detection of minute differences in 

 nearly allied objects is an essential part of natural science, the mind ac-
