Mr. Jackson has made a very careful study of Franz-Josef Land, and has brought that region into a condition of knowledge similar to that which the different Peary expeditions have brought to the north of Greenland. His narrative is simple and direct, virtually a transcript of notebook and diary, without embellishment of any kind, and with a statement of facts and conditions such as they appeared almost at the instant of time of their occurrence. While indisputably impressing a truthfulness and reality, it can not be said that this method adds to the readableness of the book, which is overburdened with repetitions, frequently in identical words and sentences, to a useless and, one is tempted to say, most distressing extent. It is to be regretted that an explorer of the marked energy, routine, and persistence which are Mr. Jackson's qualities should have faltered in what by some travelers has been considered the most arduous part of their task--the proper preparation of a report--for surely it can not be conceived that a good purpose was subserved, either in a popular or scientific aspect, in the publication of wholly unimportant matter, over and over repeated, merely because it formed part of an official diary. The work is abundantly illustrated throughout with half-tone reproductions from photographs, taken by Jackson and his companions, that give a vivid reality to the journey which no amount of word-painting, even when so skillfully handled as by the present author, could prove a substitute for. Scientists will be gratified to know that supplemental reports, prepared by specialists in different departments, may be expected before long to fill out the full scientific aspects of the exploration.
