SQUALLS DIVE IS
 TOLD IN DETAIL
Continued from Page 1)

Continued from Page D bridge. AS this word was received by the man below in the control room, it was relayed to the crew at their stations.
 aThe boat was rigged by men as- signed to the various compartments On completion of the rigging, it was reported by telephone to the con- trol room. The diving officer was particularly charged with super vising the rigging of the control from the control room, and would check off the various operations on a check-off board.
 Personal Instruction
 'In addition, the chief of the boat made a personal inspection of the boat in company of two designed officers charged with checking the rigging of the compartments for which they were responsible.
 'sThe communications officer, Lieu tenant J. c. Nichols, was assigned to the specific duty of checking the rig for diving in the forward Tor pedo room, forward battery and of ficers' compartments.
 aThe comparments aft of the control room were checked by Ensign J. n. Patterson (one of the victimS), l, who was assigned the duty of as- sistant Engineering officer.
 'sThough I did not personally witt ness their verbal reports to the div ing officer, I am told that both Nich- ols and Patterson reported to Lieut.. w. T. Doyle, Jr., that their respect i've compartments were rigged for diving.
 Message Sent Commandant
 "A message was sent to the com- mandant (of the Portsmouth Navy Yard) and report was received from the depth control officer that the ship was rigged except for the high induction, coming hatch, and engine exhaust valves and the an- tenna trunk fiapper.
 "On receipt of word, the order was given to send out the actual div ing signal. On receipt of word that his message had been transmitted and receipted, word was sent to the control room to stand by to dive. This word was passed throughout the ship by battle telephone.
 Rigged Own Telephones
 'sThe telephones" Naquin testified, aordinarily are not rigged for dives later on. I took this special pre- caution of rigging telephones in all compartments so that additional means of communication would be available for instant use.
 "On this particular dive. I de- scended through the coming tower and heard the first blast of the div ing alarm sound.
 "On sounding the first blast, the activities in the control room were essentially these:
 'sThe hydraulic manifold operator watched the indicator board to de- termine when the engine exhaust valves were closed. On the Squalus, required a report from the engine room by battle telephone when the valves were actually closed.
 Closing of Valves
 @On seeing that these valves were closed. it then was practicable to close the high inductions. Actually these consist of one high induction and supply ventilator for hull ven- tilation. These are closed by a single movement on a single lever on the hydraulic manifold.
 With the closing of the coming hatch, engine exhaust, engine induc- tion, ventilation and intake valves, the vessel should have been water tight, but it was standard procedure to admit high pressure into the con- trol room to build up the air pres sure. as indicated by barometer.
 When the diving officer received word that the pressure was correct. the diving officer ordered by hand signal-two fingers-the sounding of the second diving blast. This signal meant to proceed with the dive. The vessel proceeded downward"
 Naquin closed his narrative at this point and submitted to questioning by the board.
