During the summer months the prevailing winds came from the north-east, sweeping in over the Iranian plains, by the time they reached us they were bone dry, this was a good thing really because we sweated profusely in that heat and were rapidly cooled by evaporation. Occasionally for a couple of short periods in the summer humid winds would blow in from the Persian Gulf and then it was most uncomfortable, shirts would be sodden and dark with sweat and if they dried before being washed they would be stained white with salt. We had our laundry done twice a week by the dhobi but that was inadequate so we did our own in between times; in the bone dry air a pair of slacks could be worn 15 minutes after washing. One of our lads, mimicking the dhobi by bashing wet laundry on a flat stone was put on a charge for damaging government property; he was acquitted after enlightening the officer who obviously had never done his own laundry. One piece of equipment supplied by the army for which I was very grateful was the chargul, a water bottle made of a coarse canvas similar to fire hose canvas that worked on the same principle as the chatty. Drawn new from the QM stores it would not hold water but had to be soaked until the canvas had swollen; filled with water and hung outside in the air it provided a beautifully cold drink in a fairly short time. This evaporation principle was also adopted to lower the temperature inside ambulances by means of a cuscus tatty; this consisted of a four-sided wooden frame with chicken wire front and rear, the cavity was filled with what we called camel thorn. Water was pumped up from a tank and sprayed over the unit; air passing through the moist camel thorn was then directed into the body of the ambulance to cool the interior. No.5 ADVANCED BASE WORKSHOPS The compound covered quite a large area the exact size of which I can't say but it was spread out over a vast expanse of desert with the various workshops located in no apparent order. There were no metalled roads but between the buildings a hard travelling surface was obtained by putting discarded engine oil over the loose sand and traffic soon firmed this up For heavier loads a two-foot gauge Decauville track was laid between the main buildings and trucks were hauled by a Lister powered locomotive. For off-loading really heavy equipment within the compound a metre-gauge spur line branched off from the main line linking Turkey with Basra.
