(6.) The general idea of all the mountings I saw was narrow axles and high wheels, whereas, for all trekking purposes, it should be broad space between the wheels and low wheels. This was amply proved to us by the number of times the high-wheeled narrow mountings upset on rocky ground, whilst the broad low type went along steadily. The 12-pounder gun itself did its work beautifully, shooting hard and lasting well, and owing to the dry climate of Africa we had no trouble at all to keep the guns clean and all gear in good order. (7.) Perhaps the most troublesome defect of all was that the gun-carriage had no brake fitted. The gunnery drill-book system of "lash gun wheels" may be at once erased from the book for all practical purposes over any rocky or bad country; it simply, as we soon found, tears the wheels to pieces, and chokes the whole mounting up. An ordinary military Scotch cart brake, or a brake fitted as the trek wagons here have, under the muzzle of the gun on the forepart of the wheels, acts very well, and my bluejackets, although not carpenters, fitted these for me. They are screw-up brakes. The sighting of the gun (drum and bar system) cannot be beaten, I think. Perhaps a V-shaped notch to give one the centre of the H, or hind sight, might be an improvement, as here personal error often occurs. Lieutenant, now Commander, Ogilvy, R.N., always made his men correct their final sighting of the gun for elevation from about six paces in rear of the trail, and my experience is that this is a small but important matter, especially for fine shooting say at a trench at 5,000 yards, which merely appears to one as a line on the ground. One invariably finds that the gun, with the eye of a man laying close up to the hind sight, is laid slightly short of the object; so this should be noticed in the gunnery drill-book as regards field guns. _Telescopic_ sights, the patent, I believe, of Lieutenant-Colonel L. K. Scott, R.E., were sent out and used by us with the 12-pounders to fire on the trenches at Spion Kop and Brakfontein, when fine shooting was required. These sights had the cross wires much too thick, so we substituted cobwebs picked off the bushes and stuck on with torpedo composition, and these did admirably. Still this sight was not altogether a success. The power of the telescope, especially in the rays of the sun, was poor, and it took a man a long time to lay his gun with it, thus further reducing the quick-firing power of the 12-pounder reduced already by the recoiling field carriage. As to the 4.7's, it was found that the ordinary Naval small telescope, fitted on a bar and with light cross wires, could not be beaten as a sight for ranges they had to fire at. It is a very good useful glass, and it was, I believe, used both in Natal and elsewhere right through the campaign, and I unhesitatingly give it the palm.
