in shading the drawing, the nearer parts should be made darker than those distant; this causes the latter to recede, having the appearance of distance. In Fig. 10, we give the representation of an old gate; it is so simple that it needs no explanation. Fig. 11, which is the representation of a familiar object, is treated under a very simple effect of light and shade, the shaded parts bringing forward the light ones; this effect is called _relief_. It is of the utmost importance that the pupil should have a clear knowledge of the mode of producing this effect. We would recommend her to try the experiment of placing simple objects so as to relieve each other, and to sketch them in this manner; this will enable her very speedily to understand the method of attaining the effect. In Fig. 12, the same effect is displayed, only reversed; a mixture of light and shade throwing back the other end, which is in half tint. In Fig. 13, which is the representation of a fuchsia-leaf, the outline must be put in in the manner heretofore explained; the shading is similar to that in Fig. 8. After copying this, we would recommend the pupil to get a similar leaf, and place it in various positions, so that the light and shade will be variously disposed. This will afford excellent practice, and will accustom the pupil to draw or sketch from nature. In Fig. 14, which is the representation of a rural stile, the pupil will find the principle of relief shown in Figs. 11 and 12 again displayed; the shading behind the stumps throwing the light parts forward, and the shaded sides of these causing the back part to recede.

BY D. W. BELISLE. BOOTES.--This constellation is situated west of Asterion Et Chara, and contains fifty-four stars. It comes to the meridian the 9th of June. Bootes may be readily distinguished by the position and splendor of its principal star Arcturus, which shines with a reddish lustre, much resembling the planet Mars. This star is supposed to be nearer the earth than any other star in the northern hemisphere. Arcturus is referred to in Young's "Paraphrase," where the Almighty answers Job out of the whirlwind-- "Canst thou the skies' benevolence restrain, And cause the Pleiades to shine in vain? Or, when Orion sparkles from his sphere, Thaw the cold season, and unbind the year? Bid Mazzaroth his destined station know, And teach the bright ARCTURUS where to glow?"
