FOREST ADMINISTRATION. 209 



Every year there are issued programmes specifying the 

 subjects on which applicants for admission must be pre- 

 pared to be examined. According to the programme for 

 the year 1877, the one I happen to have before me, the 

 preliminary entrance examination through which applicants 

 must pass embraces amongst others the following sub- 

 jects : Theory of mechanics ; the general principles of 

 statics, and their application to the determination of the 

 centre of gravity; the general principles of dynamics, 

 including inertia, momentum, reaction, vital force, 

 movements of points and movements of bodies under 

 varied conditions, and the establishment of equilibrium. 

 Descriptive geometry; its application to projections 

 and perspective, embracing points, straight lines, circles 

 and planes, triangles, polyhedrons, sections and inter- 

 sections of these, tangents, cylinders, cones, lines of 

 revolution, involution, plane and conic sections, the 

 projection of shadows, and the geometrical laws of per- 

 spective. Physics : properties of bodies, gravity, specific 

 gravity, characteristics of solids, of liquids, capillarity, gases, 

 atmospheric pressure, elastic force of bodies, flotation, and 

 temperature. Accoustics : propagation of sound, and 

 distinctive characters of sound. Heat: expansion of 

 bodies in a solid, a liquid, and a gaseous state, and 

 operations by which it is affected ; hygrometry, and trans- 

 mission of heat. Optics : propagation of light, photometry, 

 reflection from plane and curved surfaces, refraction and 

 dispersion of rays, structure of the eye, optical instruments, 

 double refraction and polarization of light. Electricity 

 and magnetism : static electricity, distribution by conduc- 

 tors, measure of electric force, magnetism, dynamic elec- 

 tricity, electro-magnetism, electro- telegraphy, thermo- 

 electric currents, electric induction. Meteorology : ther- 

 mometrical observations, winds, aqueous phenomena, 

 electric phenomena, luminous phenomena. ' Chemistry : 

 chemical notations, combining proportions, theory of 

 chemical equivalents, specific heat, atomic theory, metal- 

 loids and their more important compounds, other elemen-
