A pin has a head, but has no hair

A pin has a head, but has no hair;
A clock has a face, but no mouth there
Needles have eyes, but they cannot see;
A fly has a trunk without lock or key;
A timepiece may lose, but cannot win;
A corn-field dimples without a chin;
A hill has no leg, but has a foot;
A wine-glass a stem, but not a root;
A watch has hands, but no thumb or finger
A boot has a tongue, but is no singer;
Rivers run, though they have no feet;
A saw has teeth, but it does not eat;
Ash-trees have keys, yet never a lock;
And baby crows, without being a cock.
