A Manual of Philippine Silk Culture. By Charles S. Banks (from 

 the Entomological Section, Biological Laboratory, Bureau of 

 Science, Manila, Philippine Islands), 53 pages and 19 plates. 

 The introduction of silk culture into these islands, if it could be 

 made a profitable industry, would be very desirable. This work is 

 intended to collate data and interest those who may wish to take up 

 the commercial production. "The Bureau of Science made the first 

 attempt to import and to propagate mulberry silkworms into the 

 Philippine Islands six years ago." A historical account is given of 

 the attempts of the missionaries in the early eighties and also of the 

 later efforts. The life history of the species is given in detail. An 

 account is also given of the eri or castor silkworm {Attactis ricini) 

 and of the wild silkworms of the islands. The proper "silk house" 

 is described and also the varieties of mulberry and their cultivation. 

 The manufacture, reeling, etc., and the quality of silk is also discussed.
