A little above the centre of the wheel a small pivot B (Figs. II. and III.)-is fixed, to which is attached the long strip of metal c (Figs. II. and III.). The other end of this red c is pivoted to the leg p (Fig. II.) at a point a little below the place where this leg is pivoted to the
| link 1.
The manner in which the fixed glass is fitted up has now been fully described, and we will therefore pass on to the sliding glass F (Vig. IIT.).
At the extreme ends of this glass are glued on the front surface two wooden blocks a A (Fig. IV.). These blocks are pierced sideways Through each of these holes a
| piece of string © is drawn, and the ends
secured by knots. The string will thus be left taut. The position of these blocks and the

the body at one point, F.
The next point to be dealt with is the completion of the wheelbarrow, i.¢., the fitting on of the wheel. :
A small round block is glued to the glass at the end of the front fork. This block is exactly the same size as the axle of the wheel itself, which is cut out of white wood. The wheel A, a side view of whichis shown in Fig. I1., is grooved, as a glance at the sectional view, Fig, ITT., will show.

On the sliding glass are now painted the trestles D’ p (Fig. IV.) from which the man Figures are also painted to represent the occupants of the seats in the circus, and the inevitable clown H, foreshortened by reason of his distance away from the performer on the high tight-rope, must
not be forgotten. It must be noticed that the people in the middle of the glass are smaller than those at the two ends because they are supposed to be farther away from the rope.
A circular mask is attached to the fixed glass, leaving a margin round the performer as shown
in Fig. I. Both glasses are now complete, and when they are fitted into the framework each in: its proper place, the slide is ready for exhibition.
In Fig. LV. the sliding glass is. shown in.the position it would occupy after. the man had gone through his performance on the: tight-rope.
