 Inspectors should make it a point to send in material con- 

 cerning which they are in doubt. By doing this they will aid 

 themselves in acquiring a better acquaintance with the vari- 

 ous diseases, and will aid in the detection of new diseases or 

 of the occurrence of diseases in regions from which they 

 have not been previously reported. Cartons and franked 

 tags will be supplied the inspectors for use in sending such 

 material. Many specimens can best be sent wrapped in 

 paper (newspaper does admirably). It is very important 

 that material be mailed without delay.
