"Descriptive Writing with Virginia Hamilton" was written in 2001. Scholastic regrets to inform users that Ms. Hamilton died on February 19, 2002.
Up at a promontory above the river we found Olu Igbo the lord of the forest. Placing his stick in his back pocket, the little man fell silent and bowed. It was indeed an awesome sight a giant stone effigy standing among great trees, with huge eyes and long arms spread out like wings. Hoots and warbles percolated in from the foliage; rain began to fall but its drops, intercepted by the manifold layers of leaves above, hardly touched us.
Prescriptive grammarians prefer giving practical advice about using language: straightforward rules to help us avoid making errors. The rules may be over-simplified at times, but they are meant to keep us out of trouble—the kind of trouble that may distract or even confuse our readers.
The potential standard employs two adjacent, standard, orthographic views (here, Front and Top) with a standard "folding line" between. As there is no subsequent need to 'circuitously step' 90° around the object, in standard, two-step sequences in order to arrive at a solution view (it is possible to go directly to the solution view), this shorter protocol is accounted for in the layout. Where the one step protocol replaces the two-step protocol, "double folding" lines are used. In other words, when one crosses the double lines he is not making a circuitous,90° turn but a non-orthodirectional turn directly to the solution view. As most engineering computer graphics packages automatically generates the six principal views of the glass box model, as well as an isometric view, these views are sometimes added out of heuristic curiosity.
