That are not there?

Though the birds sing small,
And apple and pear
On your trees by the wall
Are ripe and rare,
Though none excel them,
I have no care
To taste them or smell them
And you not there.

Though the College stones
Are smit with the sun,
And the graduates and Dons
Who held you as one
Of brightest brow
Still think as they did,
Why haunt with them now
Your candle is hid?

Towards the river
A pealing swells:
They cost me a quiver -
Those prayerful bells!
How go to God,
Who can reprove
With so heavy a rod
As your swift remove!

The chorded keys
