The boat ploughed on. Now Alcatraz was past  
And all the grey waves flamed to red again  
At the dead sun's last glimmer. Far and vast  
The Sausalito lights burned suddenly  
In little dots and clumps, as if a pen  
Had scrawled vague lines of gold across the hills;  
The sky was like a cup some rare wine fills,  
And stars came as he watched  
- and he was free  
One splendid instant - back in the great room,  
Curled in a chair with all of them beside  
And the whole world a rush of happy voices,  
With laughter beating in a clamorous tide. . . .  
Saw once again the heat of harvest fume  
Up to the empty sky in threads like glass,  
And ran, and was a part of what rejoices  
In thunderous nights of rain; lay in the grass  
Sun-baked and tired, looking through a maze  
Of tiny stems into a new green world;  
Once more knew eves of perfume, days ablaze  
With clear, dry heat on the brown, rolling fields;  
Shuddered with fearful ecstasy in bed  
Over a book of knights and bloody shields . . .  
The ship slowed, jarred and stopped. There, straight ahead,  
Were dock and fellows. Stumbling, he was whirled  
Out and away to meet them - and his back  
Slumped to the old half-cringe, his hands fell slack;  
A big boy's arm went round him - and a twist  
Sent shattering pain along his tortured wrist,  
As a voice cried, a bloated voice and fat,  
'Why it's Miss Nancy! Come along, you rat!'
