THE LAYING OF SUBMARINE CABLES. 113 



We may assume that the arrangement would be for the ship 

 to proceed to lay these cables in the following order : — 



1. Proceed to Port A. 



2. Lay both shore ends (18 miles), and buoy. 



3. Proceed to Port B, taking soundings on the way. 



4. Lay shore-end at B (6 miles). 



5. Continue laying main cable (245 miles) to buoy near 

 Port A. 



6. Make final splice. 



7. Proceed to pick up buoyed shore-end on long cable off 

 Port A. 



8. Splice to intermediate. 



9. Pay out 160 miles intermediate, 540 miles deep-sea, 120 

 miles intermediate, and buoy. 



10. Proceed to Port C. 



11. Lay 11 miles shore end. 



12. Splice to intermediate and pay out to buoy (100 miles). 



13. Make final splice. 



(This course assumes that the contract includes the assistance 

 of the Cable Company's repairing or other steamer to take 

 soundings ahead over the long route, otherwise the course 

 would be arranged to proceed direct to Port C after completion 

 of the short cable, taking soundings from A to C en route and 

 laying the long cable from C to A.) The lengths of each type 

 and approximate weights will be : — 



35 nautical miles shore-ends 550 tons. 



625 ,, ,, intermediates 1,850 „ 



540 ,, „ deep-sea 800 „ 



1,200 nautical miles all told... 3,200 tons. 



This cable would be best distributed on board as regards 

 weight and order for laying as shown in Fig. 53). The main 

 tank would be loaded with the bulk of the lojag cable in the 

 following order : — 



100 miles intermediate coiled in bottom of tank. 



Top end spliced to bottom end of 



11 miles shore-end. 



200 miles deep-sea type. 



Top end spliced to bottom end of 



160 miles intermediate. 



14 miles light shore-end. 



4 miles heavy shore-end.
