Such lives and such deaths are the seed of the Church.

It is they that speak the loudest in calling for the fresh labourers; and though the Zanzibar Mission has drifted far away from the field of Mackenzie's labours, and has adopted a different system, and though his toils in Natal never were allowed to continue long enough in a single spot for him personally to reap their fruits upon earth, not only has his name become a trumpet call, but out of his grave has sprung, as it were, a mission in the very quarter where, had he been permitted, he would have spent his best efforts, namely, the free Zulu country, Panda's kingdom, to the north of the Tugela.
It has been already mentioned that Mr.and Mrs.Robertson had removed thither, from their station upon the Umlazi, taking with them a selection of their Christian Kaffirs, and settling, with the king's permission, at a place called Kwamagwaza.

At first they lived in a waggon and tents, for, delicate and often ill as was Mrs.Robertson, she shrank from no hardship or exertion.

She writes, "My own health has been wonderful, in spite of much real suffering from the closeness of the waggon, and exposure to rain or hot sun, which is even more trying.

I often have to sleep with the waggon open, and a damp foggy air flowing through to keep me from fainting, and I have often told myself, 'You might be worse off in the cabin of a steamer,' that I might not pity myself too much." A hut was soon raised, and Mrs.Robertson here ruled in her own peculiarly dignified and tender way as the mother of the whole station, keeping guard there while her husband went on expeditions to visit the king and his son Ketchewayo, the chief executive authority.
