My instructions were to go on board the dredger to inquire for any sick, and remove them, if necessary, to Kurna. On boarding the dredger I found Col. Johnson awaiting for a favourable opportunity to take a motor launch across the lake. The Captain very kindly asked me to dinner. We spent a little time scanning the country from behind a searchlight. From the dredger I had a full view of the immense fires that we had previously observed. The skipper says that they are large brick-kilns. The bricks must be manufactured on an enormous scale, as, by night, the sky is bright with flame and, by day, darkened in a black pall of smoke.
