THE INSTRUCTION OF EMPLOYEES. 51 



distinguish them from those of native moths. They were 

 taught to observe all evidences of the presence of the gypsy 

 moth, and were requested to secure by personal observation 

 as the season advanced all possible information in regard to 

 its habits. When the inspectors had gained sufficient knowl- 

 edge to enable them properly to instruct others, laborers 

 were employed, and each inspector was put in charge of a 

 few men, over whom he was given full authority with in- 

 structions to recommend the discharge of any man who 

 proved inefficient or untrustworthy. Each inspector was 

 given a short time in which to instruct his men by engaging 

 them in practical work in the worst-infested portions of 

 Maiden and Medford. Then a section (indicated by a map) 

 was allotted him, with instructions to inspect it and destroy 

 the eggs therein. When eggs were found on a tree or other 

 object, certain characters were marked upon it with white 

 paint, and the locality was designated on the map. 



As the season advanced and the extent of the region occu- 

 pied by the moth became known, it was found necessary to 

 employ two hundred and fifty men, and distribute them over 

 this region. It became evident that it was impossible for 

 one man to keep the entire field under supervision. Six 

 superintendents were then selected from among the most 

 efficient of the inspectors. Each of these was required to 

 supervise the work in several towns. When spraying began, 

 one man was placed in charge of tools and supplies, including 

 spraying apparatus and teams. A code of rules and regula- 

 tions was prepared and printed early in the season, and copies 

 were distributed among the employees. (See Appendix B.) 



Daily Reports and Records. 



Each inspector was instructed to make out daily a written 

 report of the work done by himself and men, and to incor- 

 porate in these reports his observations on the habits of the 

 moth and its parasites, notes on its distribution and all 

 useful information acquired by him in regard to the moth or 

 methods of eradicating it. In these reports the number of 

 trees, buildings, fences, walls, hedges and other objects 

 inspected daily was recorded ; the number of each on which 

 the moth was found ; the number of each form of the moth
