Of a useful whole I'm the most useful part

Of a useful whole I'm the most useful part ;

I Ve a good circulation, for I Ve a heart ;

I have two or three garments or outer clothes ;

I am closely allied to a lip and nose ;

Rags, and parchments, and jewels rare,
Rubbish and treasures within me I bear ;

The tiniest leaf I produce I can nip
With a dexterous finger and thumb at my tip ;

Though I'm often as tall as a spire to view,
If you travel far I accompany you ;

I am the Indian's light canoe :

To puzzle you more, I'm an aqueduct too ;

I'm part of a garment of olden time,
And part of a beast of a southern clime ;

And finally, now, to crown the whole,
I am your body, but not your soul !
