The sorrow & the pity

Pity the sorrows of the poor blind,
For they can but little comfort find;
As they walk along the street,
They know not where to put their feet.

They are deprived of that earthly joy
Of seeing either man, woman, or boy;
Sad and lonely through the world they go,
Not knowing a friend from a foe:
Nor the difference betwixt day and night,
For the want of their eyesight;
