APPENDIX. xxv 



38. Inspectors are to handle and mix poisons. 



39. The solution in the tank must be constantly stirred from 

 the time it is first mixed until the tank is empty. 



40. Tanks must be fastened on the wagons in such a way that 

 they cannot be overturned. 



41. If, during the spraying, a tree is found infested and un- 

 marked, it must be marked. Each time a tree is sprayed it must 

 be marked with three round dots, the size of a ten-cent piece, the 

 first set being placed five feet from the ground, and each succeed- 

 ing set an inch above. 



42. Inspectors will carefully notice the effect of the spraying 

 and record the same in their daily reports. 



43. The spray thrown on the trees must be as fine as possible. 



44. Drivers of spraying wagons, when at work, will be under 

 the direction of the inspector in whose section they are employed. 

 Each inspector will keep the time of his driver and report the 

 same. 



45. Inspectors must, when possible, draw water from the stand- 

 pipes. When hydrants are used the inspector only shall open and 

 close them, exercising great caution to open and close them slowly, 

 but not closing them so tightly as to prevent opening. 



46. At morning and at noon, before beginning spraying, each 

 nozzle must be turned into the bottom of the tank and a full 

 stream pumped for five minutes. 



Reports. 



47. The rating of superintendents and inspectors will be based, 

 not only on the quality of the work done by their men, but on the 

 fulness and excellence of their own reports. All reports must be 

 sent to the director's office and are subject to his approval. Each 

 inspector must make out his report daily and give it to his super- 

 intendent, or send it to the office (by mail or otherwise) on the 

 following day. Observations on the habits of the insect and other 

 items of interest, and any statements or complaints by citizens, 

 should be embodied in the reports. 



48. Superintendents must notice whether the streets are re- 

 ported in their proper sections. 



49. Inspectors must give time of employees on each day's 

 report. 



50. In case of the absence of an employee the inspector must 

 give the reason (when known to him) for such absence on the 

 report of the day when such absence occurs. 



51. Inspectors must observe the printed headings on reports 

 and fill spaces reserved under the same.
