PLATE VI.

107. In Problems XXVIII and XXIX find the shades and shadows of objects and their shadows on the co-ordinate planes.

108. In Problem XXX, C is a square projection or fillet on the V plane. Below this fillet and also applied to the V plane are portions of two cylinders, DD, which support the fillet C. Find the shades and shadows in elevation only.

109. Problem XXXI, given a spherical hollow, its plane parallel to V, find its shadow.

110. Problem XXXII, given a scotia moulding, the upper fillet of which is the frustum of a cone, the lower fillet is a cylinder. Find its shadow in elevation and plan.

* PLATE VIII.

112. Problem XXXIII shows a series of pediment mouldings applied to a vertical wall A. Find the shadows on the mouldings and the shadows of the mouldings on the vertical plane A.

PLATE IX.

113. In Problem XXXIV find the shadows of a given window.

114. In Problem XXXV find the shadows of the given key-block and the shadow of the keyblock on the vertical wall to which it is applied. Use the short methods of construction and use the plan only from which to take distances.

PLATE X.

115. Problem XXXVI. Given the upper portion of a Doric order, the column being engaged to the vertical wall V, see plan. The entablature breaks out over the column, see plan. Find all the shadows, using the short methods of construction and use the plan only to obtain required distances.

116. Problem XXXVII. Given a rectangular niche, as shown by the plan, having a circular head as shown by the elevation. Situated in the niche is a pedestal in the form of truncated square pyramid. This pedestal has on its four side faces projections as shown in the elevation and plan. On the pedestal rests a sphere. Find all the visible shadows in the elevation. Use the short methods of construction and use the plan only for determining distances.
