This work, labourious as it may appear, has been to me a labour of love, an unfailing source of solace and satisfaction. During my long years of official banishment to the luxuriant and deadly deserts of Western Africa, and to the dull and dreary half clearings of South America, it proved itself a charm, a talisman against ennui and despondency. Impossible even to open the pages without a vision starting into view; with out drawing a picture from the pinacothek of the brain; without reviving a host of memories and reminiscences which are not the common property of travellers, however widely they may have travelled.
