Irom a comparison of the two. Curiously enough, Apart from purely diplomatic considerations, such Holdsworth doubted the probability of any extensive adoption of either steam power or the otter trawl in relation to commercial fishing. Contrary to this forecast these very two factors, together with ice and railway facilities, have effected nothing short of a revolution in the industry. It is possible that the next decade or so may also have surprises in store as the result of trade enterprise on the one hand and scientific investigation on the other.

Mr. Afalo wisely refrains from pronouncing any strong opinions as to future developments.

After a short sketch on “Life in the Sea," in which the chief of the facts known about the life-histories of the edible fishes are mentioned, the author proceeds to describe the various processes involved in the capture and distribution of fish. These subjects receive adequate if not exhaustive treatment, and are made as interesting as possible by Mr. Aflalo's well-known popular style of writing. Then follow two important chapters on legislation and scientific investigation.
