PRIMAUY INSTRUC.TIONS. the outline as distinctly as if drawn on paper, and as easy of imitation. He will not only have a guide in drawing the sweep of the outline correctly, but, also, in marking the true proportions of the object. He will find the line n produced by the thread, drawn, as it Were, against the pitcher, touching its lip and greatest circumference; while B and c~ in like manner, serve to show the relative proportion of the stand or base to the neck. A~ corresponding to D, gives him something to go by, in producing the general form with relative regularity, and marks the variation, first seen where the handle begins. It then serves to ascertain the true form of the handle, as well as to designate the place of its lower joining with the pitcher. Thus, to show the principle. A thread and weight are not always at hand; and if they were, they do not t~erve as well as the instrument with which we draw. Hold a pencil at arm's length, look along its outline, and in like manner you may I readily ascertain the bearing, not only of the perpendicular lines, but of any others you may desire, either ror the purpose of studying your outline, or of proving it after it has been drawn. You can thus, m a measure, be your own master, and correct your own mistakes. You may not see the practical draughtaman have recourse to such expedients; but, nevertheless, he is governed by the same principles. He sees, at a glance, the relation of the parts to one another. Although he does not draw the perpendicular lines, he sees that the swell of the largest circumference of the object before him extends no farther than a perpendicular line, drawn from the lip, would touch. He sees that where the base is united to the pitcher, it is just as wide as at the neck. He sees the base is a little wider. He marks. all these points; if not on his paper, they are mentally before him; and he produces, with apparent ease, a correct drawing of the object, so just in all its proportions, that a potter shall produce a fac-simile of the pitcher, from the drawing. Such facility any one of ordinary capacity may acquire, who will take the pains and study reguired. 31. Let it not be understood, in saying this, that every one can learn to draw like Michael Angelo, or compose with the grace and charm of Raphael, any more than he who writes with grammatical accuracy, can, therefore, write like Shakespeare. There is a barrier that none can pass, who are not the gifted children of genius. Such men may have shone less brilliant in the first steps of that knowledge, by means, of which they achieved their greatness, than~manya school-fellow -
