THIS book is written especially for boys, in the hope that Mackay’s example may lead many of them to think of Africa, and devote their lives to its moral and spiritual regeneration.

I desire to tender my thanks to Mr. Eugene Stock for his permission to incorporate in this book Bishop Tucker’s account of his visit to Uganda; also to record my obligation to the Rev. John Stewart, Edderton, N.B., for his trouble in collecting from old friends several incidents of my brother’s early life.

The whole of the matter in this volume is fresh, and is not found in the larger book, "Mackay of Uganda." If it confirm and increase the good already done by that volume, I shall be richly recompensed.
