parallel lines will be found to vanish into one-and Accidental, because they were not made at first, but were found by the accidental position of the objects. We are to use them instead of the point of sight, as we shall see hereafter. But we want yet two other points, which must be thus found. Place one end of your compasses on the point (H), and pass the other from the point (F), by the dotted circular (e), to the horizontal line, where it forms the point (1), called the Accidental Point of Distance-repeat the same process with the compasses on the other side, and you will meet the corresponding point (1), the other accidental point of distance. The two new points (I I) are to be used instead of your original points of distance. We are aware our pupils may find some little difficulty in the first arranging of these points: but a careful examination of the plates with these directions, will, we hope, make it plain. The points once found, we have only to proceed as on all former occasions, using the new points instead of the old ones. Thus, from each end of the line (a), we draw lines (ff) both ways to the vanishing points (HH). In an oblique object, it is necessary we set off the dotted line (gg) both ways, in such proportion as we suppose the receding sides of the box to bear to the height-we have here made it equal, supposing our box in all directions square. From the points (gg), we draw as usual the diagonals (h h), to the accidental points of distance (11)-meeting the rays (ƒƒ), they determine the perpendiculars of the box, whence the remaining lines (ii) are readily found. Fig. 2 is a building in a similar situation, except that it is above the eye-and supposing it to be twice as long as it is wide, we set off the dotted line twice as far on the one side as on the other. This done, we proceed > exactly as before. To avoid confusion we use the same points-but it by no means follows that two oblique objects in a picture must have the same points. Unless in a row, or connected with each other, it is very little VOL. II. Hh likely that they should, as one may stand more or less aslant than the other to our eye: in which case fresh points must be found for the second object as for the first. It appears to us that the only difficulty in the above lesson is the finding of the first point (H). The direction we have given seems to us the most simple, and affording sufficient, though not entire exactness. But if the learner should find it insufficient, he must be supplied with something, (a double ruler would do,) by which to measure the angle subtended in nature by the line (b) with the ground (g), and preserve the same angle between (b) and (g) in the picture; then drawing the line (b), till it reached the horizontal (D). We hope our pupils will repeat their practice upon this rule till they become quite familiar with the process. HYMNS AND POETICAL RECREATIONS. THE LILY. A LILY tall and richly dress'd, And deck'd in colours bright and gay, The eye's delight, the garden's pride, Had bloom'd through many a summer day. In scorn of every humbler flower, Still gazing round her from her height, She mark'd the lowly Perwinkle "What is the use," she proudly said, "Of that unseen, unsightly weed- " Attracted by my brilliant hues, 'Twas thus she pleas'd, one summer day, Would yield their meanness space to grow. But it befell, that ere the sun Arose again on that proud flower, The tempest rose, and with it came The raging wind and pelting shower. Expos'd to danger from its height, While shelter'd and secure from harm, That brought the boastful Lily down. Ah! wherefore should a thing so frail, And why should wealth, and rank, and pow's, In boasted greatness too secure, Too bold upon their sunny path, Despise the lowly and the poor? And why should learning, wit, and sense, Scorn even folly for her want Of gifts themselves created not? Or elegance expend her scorn Contempt may surely ill become A brow inscribed with mercy's name A being moulded from the dust, And hasting thither whence he came; |
