DEAR SIRS,

Letter from Messrs. SIEMENS Bros.

12, Queen Anne's Gate, Westminster,

London, S.W., 14th August, 1900.

HEREWITH We beg leave to hand you our Tenders for the three sections of the Pacific Cable and for the Sounding and Surveying Operations.

Our price for any two or all of the sections would be the sum of the prices quoted for each single section, but the time of completion of manufacture and laying would be considerably less than the sum of the times needed for each section in question.

We would submit the core to a hydraulic pressure equal at least to the one to which the cable will be subject after having been submerged, so as to ensure the removal of air-bubbles, in addition to the test by an E.M.F. of 5,000 volts us provided for in the Specification.

As fully explained in the answer to Question No. 646 of the Pacific Cable Committe (1896), the two chief causes of trouble in submarine cables are air-bubbles and small particles of foreign matter. By the high voltage test the latter can be discovered, but the air-lubbles will not be detected unless hydraulic pressure is applied.

The efficiency of these tests has been demonstrated by the success of the Atlantic Cable which we have laid in 1894 for the Commercial Cable Company, and which has proved itself to be entirely free from faults during the laying and has remained so since.

We would also employ, in laying any of the cables, our method for insuring the proper percentage of slack by paying-out au auxiliary wire. We have found this system to prove of great value if ever repairing operations have to be conducted, especially in great depths such as occur in the Pacific.

In submitting our Tender herewith, we would suggest that the Deep-Sea Cables should be of the close-armoured type, which we have found very satisfactory.

For the Deep-Sea Cable in Contract No. 1 we woukl thus, for instance, propose a Specification as follows :—

CONTRACT No. 1.

"(D) Type D. (Main Cable). The served core to be covered with 22 gal-,

vanized steel wires, cach wire being well covered with a bituminous compound."

...

The galvanized steel wires to be No. 14 BW.G,, equal to 083 of an inch, etc,'

The rest of Clause (1) and the following clauses to remain unaltered, except that the sheathing wire for Type D. is to be treated the same as prescribed in Clause (L) for . the sheathing wires of Types A.A., E., and B.

This adoption of close-sheathing will increase the breaking strain of the D. Type by more than 20% (twenty per cent.).

Contract No. 2%

*(-1) Type D (Light-Deep-Sea). The served core to be covered with 17 gal vanized steel wires, each wire being well-covered with a preservative compound.”

The galvanized steel wires to be No. 14 BW.G., equal to 083 of an inch, ete." The rest of Clause (J) and the following clauses to remain unaltered, except that the sheathing wire for D Type is to be treated the same as prescribed in Clause (M) for the sheathing wires of Types A.A., E., B. and D3.

The adoption of close sheathing would increase the breaking strain of the D Type by a little over 5% (five per cent.).

The advantages which we have found practice to result from this alteration are that the breaking strain is increased, and that the danger of galvanic corrosion is avoided.

We have in our possession a specimen of picked-up cable, constructed with separately covered sheathing wire, in which such corrosion had extended for miles, and in places some of the sheathing wires had been completely caten away. The possibility of such action taking place can easily be proved by placing two taped wires into salt water and connecting their ends protruding from the liquid through a galvanometer, when a current will be observed.
