"The breadfruit is a large, globular fruit of a pale-green color, about the size of a child's head, marked on the surface with irregular six-sided depressions, and containing a white and somewhat fibrous pulp, which when ripe becomes juicy and yellow. The tree that produces it grows wild in Tahiti and other islands of the South Seas. it is about 40 feet high, with large and spreading branches, and has large bright green leaves, deeply divided into seven or nine spear-shaped lobes. The eatable part of this fruit lies between the skin and the core, and it is as white as snow and somewhat of the consistence of new bread."—(Charles Leonard-Stuart, 1911)

"The <em>shoulder-blade</em> is a large, flat, three-sided bone, which is placed on the upper and back part of the chest. On the outer side it has a saucerlike cavity on which the rounded head of the arm bone rests." &mdash; Blaisedell, 1904

"The <em>leg</em> consists, like the forearm, of two bones. The larger, a strong, three-sided bone with a sharp edge in front, is called the <em>tibia</em>. It is commonly known as the shin bone. The smaller bone, bound at both ends to the tibia, as a pin is to a brooch, is called the <em>fibula</em>, meaning a buckle or clasp. It is a long, slender bone on the outside of the leg, and is lower end forms the outer ankle." — Blaisedell, 1904

These are two-sided ladders used mostly for interior work, though they are handy too for certain exterior painting tasks. A plank placed on any rung of one and extended to that of another makes a splendid scaffold from which to paint a side wall. Four or six trestles with planks between them make up a scaffold from which a ceiling can be easily reached. Trestles are made substantially like long ladders. Two are hinged and permanently fastened together at the top. Made in lengths of 6, 7, 8, 10, 12, 14 and 16 feet long.

"Science has succeeded in classifying the thousands of known crystals in six systems, to each of which belongs a number of forms having some property in common. In order to classify these different crystals, the existence of certain lines within the crystal, called axes, is assumed, around which the form can be symmetrically build up. These axes are assumed to intersect in the center of the crystal, and to pass through from one side to the other." &mdash; Hallock, 1905
