<a name="l63"></a>&quot;To a Waterfowl
<a name="l64"></a>by William Cullen Bryant
<a name="l65"></a>
<a name="l66"></a>Whither, 'midst falling dew,
<a name="l67"></a>While glow the heavens with the last steps of day,
<a name="l68"></a>Far, through their rosy depths, dost thou pursue
<a name="l69"></a>Thy solitary way?
<a name="l70"></a>
<a name="l71"></a>Vainly the fowler's eye
<a name="l72"></a>Might mark thy distant flight to do thee wrong,
<a name="l73"></a>As, darkly painted on the crimson sky,
<a name="l74"></a>Thy figure floats along.
<a name="l75"></a>
<a name="l76"></a>Seek'st thou the plashy brink
<a name="l77"></a>Of weedy lake, or marge of river wide,
<a name="l78"></a>Or where the rocking billows rise and sink
<a name="l79"></a>On the chafed ocean side?
<a name="l80"></a>
<a name="l81"></a>There is a Power whose care
<a name="l82"></a>Teaches thy way along that pathless coast,--
<a name="l83"></a>The desert and illimitable air,--
<a name="l84"></a>Lone wandering, but not lost.
<a name="l85"></a>
<a name="l86"></a>All day thy wings have fann'd
<a name="l87"></a>At that far height, the cold thin atmosphere:
<a name="l88"></a>Yet stoop not, weary, to the welcome land,
<a name="l89"></a>Though the dark night is near.
<a name="l90"></a>
<a name="l91"></a>And soon that toil shall end,
<a name="l92"></a>Soon shalt thou find a summer home, and rest,
<a name="l93"></a>And scream among thy fellows; reed shall bend
<a name="l94"></a>Soon o'er thy sheltered nest.
<a name="l95"></a>
<a name="l96"></a>Thou'rt gone, the abyss of heaven
<a name="l97"></a>Hath swallowed up thy form; yet, on my heart
<a name="l98"></a>Deeply hath sunk the lesson thou hast given,
<a name="l99"></a>And shall not soon depart.
<a name="l100"></a>
<a name="l101"></a>He, who, from zone to zone,
<a name="l102"></a>Guides through the boundless sky thy certain flight,
<a name="l103"></a>In the long way that I must tread alone,
<a name="l104"></a>Will lead my steps aright.
