As correlations, represent the trillium in colour and design an embroidery pattern based on it.
Lessons similar to that on the trillium may be based on adder's tongue, Indian turnip, Dutchman's breeches, violet, and clover.
ADAPTATIONS OF ANIMALS
It is not considered necessary to go outside the list of ordinary animals to find sufficient illustrations of adaptations, and it is recommended that attention be given to these during the study of animals prescribed for the regular Course. This may be supplemented by an occasional review of adaptive features for the purpose of emphasizing the general fitness of animals for their varied habits and surroundings. Care must be taken lest the attempt to explain structures by adaptation be carried to an extreme, for it is impossible to account for all the variations in animal forms.
The following list contains a few of the many examples of adaptations to be met with in the Course prescribed for Forms II and III.
The horse walks and runs on the tips of its toes; this gives greater speed.
Wild animals of the cow and deer kind can swallow their food hastily so that they may retire to a safe retreat; there they regurgitate the food and chew it. The domesticated animal retains this habit, though there is no longer a need for it.
The wood-hare's fur is brown in summer, hence its enemies cannot see it against the brown grass and moss; in winter its colour is white, which, against the snow, is a protective colour.
The porcupine is very slow, but its colour and shape make it almost impossible to distinguish from a knot on a log. Its quills form an effective protection when it is discovered.
The feet of the squirrel are adapted for climbing and its teeth for gnawing wood and for opening nuts. The tail serves as a balancing pole for leaping from tree to tree and in winter it acts as a protection from cold.
