Inspection House 



The inspection house (PI. 11, fig. 1) consists of an inspector's office and 

 an inspection room. This house is enclosed by a high wire fence, and 

 the gates and doors are always kept locked. Only those responsible 

 for the proper conduct of the work are provided with keys. In special 

 cases passes are issued to interested persons good for the day of issue 

 only. 



The inspector's office is 12 by 19 feet, and is provided with three 

 windows, two skylights the entire width of the room, and three doors, 

 one of which opens into the inspection room. Only such furniture as 

 is necessary to care for the inspection records, etc., is kept in this 

 office, and under no conditions is nursery stock inspected in this office. 



The inspection room is 19 by 30 feet, and is provided with four 

 windows, four skylights the entire width of the room, eight venti- 

 lators, and four doors, all of which are thoroughly screened with cop- 

 per wire mesh (40 meshes to the inch). The floor and about three 

 feet of the walls are made of concrete, the remainder of the walls being 

 made of galvanized iron. It is possible, therefore, to thoroughly 

 flush or S3rringe the floor and walls with water or a disinfectant without 

 fear of damage. 



The furnishings of the inspection room consist of five white enameled 

 tables on wheels on which is placed the material for inspection, four 

 white enameled stools, three white enameled refrigerators (used to 

 safeguard perishable material), a small sterilizer, a stove, a sink for 

 washing the hands, scales, and white enameled trays for sterilizing 

 small quantities of seed, cuttings, etc., with bichloride of mercury, and 

 one white enameled bucket containing a weak solution of bichloride of 

 mercury for washing the hands after handling suspicious material. 

 Long white coats are always worn when inspecting material. Soiled 

 coats are kept in a galvanized iron bucket until they have been thor- 

 oughly disinfected and laundered. The inspection room is cleaned 

 daily and fumigated or washed down with formaldehyde as the oc- 

 casion demands. (See Plate 12.) 



The quarantine greenhouse is 70 feet long by 20 feet wide, and is 

 divided into 14 units, six of which are 14 feet by 7 feet four inches, and 

 ' eight of which are 7 feet 8 inches by 7 feet four inches. A three-foot 

 corridor extends the entire length of the structure. To enter a unit 

 from the corridor it is necessary to pass through a vestibule 3 feet by 

 3 feet which is provided with two doors, one opening into the corridor 

 and the other into the unit. All doors and ventilators are thoroughly 

 screened with the copper wire previously described. The ventilators 

 are so arranged that they can be controlled from the corridor, thus
