The South African Constabulary by the middle of the year had grown into an effective force, and were operating from the vicinity of the railways and occupying fortified posts, and thus rendering themselves exceedingly valuable in checking the efforts of the enemy to pass through the cordon around the cleared districts. The Boers, by the loss of their ox-waggons, were seriously impeded in regard to their supply arrangements, and the series of captures which took place in all parts of the country made a considerable drain on their numbers in the field. Still, small gangs of three to four hundred men roving loosely over the country could, in cases of emergency, concentrate and cause vast trouble and annoyance and even danger to the small mobile columns, broken up as they were, in order to operate over vast areas in search of the scattered hordes. Viewing the intense labour and increasing strain suffered by the Commander-in-Chief at this time, it is pleasing to quote the letter of an officer competent to speak regarding the magnificence of the steady if slow work that was being accomplished:-- "We are eleven hours a day in the saddle on patrol duty, and good solid work is being done by mobile columns. You will not get much of our movements through the Press, as the policy of secrecy is really the only safe one with the Cape Colony now undermined by rebels from north to south.

The mortality was certainly high, but on strict inquiry it was found that mainly through the ignorance, listlessness, and idleness of the Boer mothers the sick infants were treated wrongly or neglected. Dr. Jane Waterston, late President of the Women's Rand Relief Committee, in a letter to the _Cape Times_, with level-headed brevity discussed some points which the Boer sympathisers had carefully ignored. She pointed out that--
