What reading level is Birds'-Nesting : a Handbook of Instruction in Gathering And Preserving the Nests And Eggs of Birds for the Purposes of Study book?
To quickly assess the difficulty of the text, read a short excerpt:
Salvin's cabinets are so constructed that the drawers, of different depths, are interchangeable.
This is effected by placing the runners, which carry the drawers, at a fixed distance from each other, and making the depth of each drawer a multiple of the distance between the runners. For example : if the runners are f of an inch off each other, then let the drawers be 1£, 2J, 3, 3fr, 4£, etc., inches deep.
All these drawers will be perfectly interchangeable, and a drawer deep enough to hold an o...strich's egg can, in a few moments, be placed among those con- taining warblers'. • • • Mr. Salvin's plan of arranging the eggs is equally simple, and admits of any amount of change with very little trouble. Each drawer is divided longitudinally by thin slips of wood into three or more parts, about 4 to 6 inches across, as may be convenient. A number of sliding stages are then constructed of card-board, by cutting the card-board half through, at exactly the width of the partition, and bending the sides down to raise the stage to the required height.
