The experiment has been made at the Moscow Technical School for twenty consecutive years with many hundreds of boys; and, according to the testimonies of the most competent judges at the exhibitions of Brussels, Philadelphia, Vienna and Paris, the experiment has been a success. The Moscow school admits boys not older than fifteen, and it requires from boys of that age nothing but a substantial knowledge of geometry and algebra, together with the usual knowledge of their mother tongue; younger pupils are received in the preparatory classes. The school is divided into two sections--the mechanical and the chemical; but as I personally know better the former, and as it is also the more important with reference to the question before us, so I shall limit my remarks to the education given in the mechanical section. After a five or six years' stay at the school, the students leave it with a thorough knowledge of higher mathematics, physics, mechanics, and connected sciences--so thorough, indeed, that it is not second to that acquired in the best mathematical faculties of the most eminent European universities. When myself a student of the mathematical faculty of the St. Petersburg University, I had the opportunity of comparing the knowledge of the students at the Moscow Technical School with our own. I saw the courses of higher geometry some of them had compiled for the use of their comrades; I admired the facility with which they applied the integral calculus to dynamical problems, and I came to the conclusion that while we, University students, had more knowledge of a general character, they, the students of the Technical School, were much more advanced in higher geometry, and especially in the applications of higher mathematics to the most intricate problems of dynamics, the theories of heat and elasticity. But while we, the students of the University, hardly knew the use of our hands, the students of the Technical School fabricated _with their own hands_, and without the help of professional workmen, fine steam-engines, from the heavy boiler to the last finely turned screw, agricultural machinery, and scientific apparatus--all for the trade--and they received the highest awards for the work of their hands at the international exhibitions. They were scientifically educated skilled workers--workers with university education--highly appreciated even by the Russian manufacturers who so much distrust science.
