If such a course as this be not sufficient of itself to fill up two years of a tolerably studious life, we must acknowledge ourselves unable to take the measure of a common man's capacity. That it has so much in common with the pursuits of an engineer, as to justify the attempt to educate, even in part, the artillerist and the engineer together, appears to us to be a very untenable opinion. We are, therefore, strong advocates for a separate Engineer College, which, as well as the Artillery College, we should, as much as possible, feed from the preliminary school - encouraging youths to enter it who had exhibited special tastes for architecture, the application of steam-power, drawing, mechanics, geodesy, and topography. The school itself might advantageously be placed at Chatham, or We do not see any necessity for carrying engineers of the primary school or admitted after examination into the school of application from civil life, should enter as lieutenants with local rank such rank to be confirmed and full time allowed after they have completed their course of training, and been appointed to do duty with their respective corps. The course of the engineer school, like that of the artillery, should extend over two years, and there should be periodical examinations in both. We would assign the same limits to the staff school, the examination for admission into which ought to be strictly competitive; and in order to qualify officers for this, arrangements must be made for affording to them opportunities of study, while doing duty with their regiments, as well in the colonies as at home. Mr. Sidney Herbert, in his speech of June, 1856, has sufficiently explained how this is to be done. At the headquarters of every division, or at convenient places at home and abroad, officers of instruction should be stationed, who, by lectures and otherwise, may guide their comrades in their endeavours to render themselves accomplished soldiers. For it forms part of our plan that promotion shall not take place, from the junior to the senior ranks, without an examination; |
