BLIND CHILD
They tell me Father, that tonight
You'll wed another bride
That you will clasp her in your arms
Where my poor Mother died
 
They say her name is Mary, too
The name my Mother bore
They say, she'll be so kind an' true
As the one you loved before
 
And is her step so soft and low
Her voice so meek an' mild
Do you think she'll be so kind an' true
To your blind and helpless child
 
There hangs her picture on the wall
Her books are lying there
An' there's the harp her fingers touched
An' there's her vacant chair
 
Beside the chair, I used to kneel
To say my evenin' prayer
O Father, it would break my heart
I could not meet her there
 
O Father, let us kneel right here
And to our Father pray
That He will lead you by His hand
Thru life's long wearisome way
 
The prayer was ended an' a song
I'm weary now, she said
Her Father took her in his arms
An' laid her on the bed
 
And as he turned to leave the room
A joyful cry was given
He turned an 'caught the last sweet mile
The blind child was in Heaven
