objects, and the individual number is prefixed to the regular num- 

 bers, instearfl of added, and the day of the month comes first. Thus, 

 the example quoted, a specimen collected on August 12, 1899, would 

 be 1-12-8-99, 2-12-8-9.9, and so on. 



Mr. Ball replied that the system referred to by Mr. Caudell related 

 to keeping slides of embryological and histological material, and 

 while the date sj^stem part of it was the same, the application was 

 quite different. He had been using the system five years before that 

 one was published. He also said that every collector ought to be able 

 to give the genus of the specimens taken, but that if he could not, a 

 few descrij)tive words would serve to identify the species when the 

 material was worked over. He suggested that it be borne in mind 

 in the discussion that the present system was not offered as an 

 improvement upon the systems of Messrs. Felt, Hopkins, and Forbes, 

 nor for any laboratory where they had heljj enough to carry out one 

 of these systems, but that he thought that it was an improvement 

 upon the system in use in the majority of economic laboratories and 

 that the date system feature might be incorj)orated into any S3'stem 

 to advantage. 



Mr. Ashmead indorsed Mr. Hopkins's system and said that he 

 always put the name of the collector on the specimens received at the 

 museum. He ordinarily used two labels, but three were used when 

 the original label of the collector was retained. He thought it of pri- 

 mary importance to accompany the specimen with the name of the 

 collector. 



Mr. Bruner agreed that the name of the collector should always 

 appear and said that he used printed labels. 



The session then adjourned to meet at the capitol at 9 o'clock the 

 next morning for the purpose of looking over the State museum, 

 returning to the high-school building at 10 a. m. for the morning 

 session. 



MORNING SESSION, AUGUST ^4, 1901. 

 Mr. Howard read a paper entitled : 

 A PRELIMINARY REPORT ON THE SAN JOSE SCALE IN JAPAN. 



By C. L. Marlatt, Washington, D. C. 



The investigation of the San Jose scale in Japan by the writer has 

 reached the stage when it is possible to give a definite conclusion on 

 the question of original home so far as Japan is concerned. The 

 report is provisional only in the sense that some work remains to be 

 done in the northern provinces, which can hardly alter the conclu- 

 sions, and that time and facilities are lacking to make it full and 

 complete. 



In the three months alread}^ spent in Japan the writer has exiDlored 

 the main islands pretty thoroughl}^ from Tokio southward to the
