of persons connected with fishery interests, held in Chicago Oct. 16, 
1893. The papers cover a wide range of subjects, and being the views 
of men qualified by experience and study to speak upon the subjects 
treated, are of practical worth. A synopsis of the topics discussed in- 
cludes: 1. Fishery laws and administration of the fisheries. 2. The 
sciences in relation to fisheries and fish-culture. 3. Methods of capture, 
utilization and distribution of fishery products. 4. Fish-culture. 5. 
The world’s fisheries. In addition, an interesting paper is contributed 
by G. F. Kunz on pearls, and the utilization and application of the 
shells in which they are found, in the ornamental arts, as shown at the 
World’s Columbian Exposition. The illustrations of this article are 
beautiful both in subject and execution.
