The delay in the retreat of tho Boers from Natal is pareiv explained by the cable stat ing that ihey have "moved 90,000 railway, sleepers from that place to the Transvaal. The object the enemy have in view by taking these sleepers is to prevent the British forces from usimr them to repair the line, after the Boers "have destroyed it, and, perhaps, they intend to construct a line of rail to as sist them in their movements from one part of their defensive lines to another along the. Vaal River. We outline the situation of the Boer armies at the present time as given in the latest despatches as follows:—At Pomeroy, some 58 to 40 miles duo east of Ladysmith, their left flank is entrenched, the passes in tbe Biggarsberg mountains in that vicinity are all occupied by their forces, estimated to number SOCO men. From Pomeroy the moun tains of this range form a bend ing to the north. At Waschbauk Station the arc of the circle is formed by the range turning again to tho south and joining the Drakensbergs, a little to tho west of Lady smith. Tho little village of Biggarsberg is situated near Waschbauk, and about 14,000 Boers ere said to be entrenched at that point. We presume that these are there to keep General Buller's forces from gaining pos- j session of Wessel's Nek, which would give j the force holding it the control of the rail way to Dundee. Between Pomeroy and Wessel's Nek lies Heipmakaar, where the road leading from Dundee to Ladysmith wends its way through the mountains. There is every reason to believe that this road is well guarded by a strong force, for if the British were allowed to obtain possession of this road, they would cut the Boer lines in two. and fiauk both parts and compel them to retire. The road from Dundee past Help makaar to Ladrsmith became famous in the early pare of the war, as it was by this route that the British force, under General Yule, retreated after the battle of Impati Hill.
