(d) The 150 and 100 pairs enamel and cotton

covered and lead sheathed cables under itama 14 and

15 are intended for use between the terminations

of the dry core cables outside the Post Office, and

the distribution frame in the switchboard room. This

cable will be impregnated with beeswax so as to

form an airtight seal to the dry core cable. The

two cables would be jointed together in the "straight

through" boxes included under asot ions C and D. An

alternative method of leading in would be to carry

the dry core cables right into the exchange TOOM,

and there terminate them by means of a short length

of this beeswaxed cable through an ordinary lead

sleeve joint. If the building is suitably arranged

this latter method is in our opinion the best, but

if it is awkward to take the dry core cable into

the exchange then the original scheme must be

followed.

(e) The G.P.0. detector is replaced with a

test ing set, item 8, which would be useful for a

variety of tests to both outside wires and switch-

board.

(f) On several sections the Colony includes

both test boxes, and distributing boards for the

full number of wires in the cable. As a principle

a pole distributing box

with lightning protectora

which should be fitt ed

is employed for die-

tributing to open wires and a distribution board

is not required. There a cable is carried under-

ground into a building, as at No.5 police station,

then a distribution case should be provided.
