d crossings and points in yards where there are in-sulated sections of third-rail, underground cables or jumpersare installed. These cables are provided with a varnished short time only. All jumper repair work is taken care of byfour men, two of whom are splicers. Whatever excavation isnecessary is done by the regular section gangs. THIRD-RAIL PROTECTION For making repairs to the third-rail protection boards, twocarpenters are employed. The field work is kept to a mini-mum by making the boards of a specified length in the shopand keeping a stock of these and of the posts on hand. Thechief repairs to the protection board have consisted in replacingthose damaged through accidents. APPROACHES A change has been found necessary in the wood side-ap-proach boards which are placed at switches where the carshoes approach the third-rail at an angle or from a cross-over.These approach boards were originally set at an angle of aboutforty-five degrees with the horizontal, but this slope proved too

CABLE CLAMPS AND SOCKETS FOR WIRE OF DIFFERENT SIZES USED IN TEMPORARY WORK TO SECURE JUMPERS TO THE THIRD-RAIL cambric insulation, covered with lead protected by jute andasphalt and are laid directly in the ground. The jumpers havebeen subjected to some mechanical injury on some sections, andon account of this, where there is likely to be a large amountof track work it has been found advisable to install the jumpersin ducts. The ducts terminate in concrete posts which are ofsufficient strength to withstand a chance blow from pick orshovel without injuring the cable. Into these ducts are drawnjumpers having a varnished cambric insulation and braid cover-ing, the lead, jute and asphalt not being considered necessary.The concrete posts are provided with terra-cotta caps whichfit over the end of the jumpers where they are exposed to theweather. It frequently happens that temporary jumpers between sec-tions of third-rail are necessary. For this purpose a specialcable clamp has been used.
