These are examples of anapestic trimeters--though as is common with anapestic lines, most begin with an iambic foot: * / | * * / | * * /, a common instance of substitution.

                           I went to the Garden of Love,
                               And saw what I never had seen;
                             A Chapel was built in the midst,
                               Where I used to play on the green.

                             And the gates of this Chapel were shut
                               And "Thou shalt not," writ over the door;
                             So I turned to the Garden of Love
                               That so many sweet flowers bore.
                                                    --William Blake

                                 The woods are haggard and lonely,
                                     The skies are hooded for snow,
                                 The moon is cold in Heaven,
                                     And the grasses are sere below.
                                 The bearded swamps are breathing
                                     A mist from meres afar,
                                 And grimly the Great Bear circles
                                     Under the pale Pole Star.
                                 There is never a voice in Heaven,
                                    Nor ever a sound on earth,
                                Where the spectres of winter are rising
                                    Over the night's wan girth.
                                There is slumber and death in the silence,
                                    There is hate in the winds so keen;
                                And the flash of the north's great sword-blade
                                    Circles its cruel sheen.
                                The world grows agèd and wintry,
                                    Love's face peakèd and white;
                                And death is kind to the tired ones
                                   Who sleep in the north to-night.
                                                    --William Wilfred Campbell
