If the learner can but rehearse the necessary definitions and rules, and perform the simplest exercise of judgement in their application, he cannot but perceive what he _must say_ in order to speak the truth in parsing.

His principal difficulty is in determining the parts of speech.

To lessen this, the trial should commence with easy sentences, also with few of the definitions, and with definitions that have been perfectly learned.

This difficulty being surmounted, let him follow the forms prescribed for the several praxes of this work, and he shall not err.

The directions and examples given at the head of each exercise, will show him exactly the number, the order, and the proper phraseology, of the particulars to be stated; so that he may go through the explanation with every advantage which a book can afford.
