As Captain's Yeoman, I often had to seek this Signature.

I hadn't seen this signature in over 36 years until my shipmate, QM3 Dennis Milliken sent me a copy of his
Advancement in Rate Certificate, on which was this familiar signature.. and it brought back an instant rush of
emotions!
I actually admired Capt. Harris' signature, and tried to make
my own appear as good. Capt. Harris had unusually fine penmanship, and, as you see here, a fine hand with the pen.

Hannah's Commanding Officers
This old Hancock Sailor still hears calls over the old familiar
1MC...
"Liberty call, Liberty
call..."
"Taps, taps now lights
out. Maintain silence about the decks. The smoking lamp is out. Now taps."
"Now reveille, reveille.
All hands heave out and thrice up. The smoking lamp is lit in all berthing spaces. Now Reveille, Reveille!"
"Sweepers man your
brooms; clean sweep down, fore and aft.. take all trash and garbage to the fantail..."
"Now hear this, now

"Now set the Special
Sea and Anchor Detail..the Officer of the Deck has changed his watch from the hanger bay to the Bridge...prepare

"Single up all lines... Haze Gray and Underway... nite lads!"
"Now relieve the watch..."
"General Quarters,

"Now hear this, now

"... man overboard,

"Now hear this, now

"Now lay before the
