1. Put parentheses ( ) around each prepositional phrase.
2. Underline subjects once, finite verbs twice, and label complements (“PN,” “PA,” “IO,” “DO”).
3. Place brackets around each subordinate clause. If the clause functions as a noun, label its function (PN, IO, DO, OP) above the opening bracket. If it functions as an adjective or adverb, draw an arrow from the opening bracket to the word that the clause modifies.
4. Put a vertical line at the end of every main clause.
5. Put a box around every gerund and gerundive. If it is a gerund indicate its function over the box. If it is a gerundive, draw an arrow to the word it modifies.
6. Put an oval around every infinitive and indicate (as in three above) its function.
The actual, prosaic house in which the Pirates apparently lived, was
a mile from a mining settlement on a beautiful ridge of pine woods sloping
gently towards a valley on the one side, and on the other falling abruptly
into a dark deep olive gulf of pine trees, rocks, and patches of red soil.
Beautiful as the slope was, looking over to the distant snow peaks which
seemed to be in another world than theirs, the children found a greater
attraction in the fascinating depths of a mysterious gulf, or "cañon," as
it was called, whose very name filled their ears with a weird music.
