gg PROTECTION OF PLANTS. 1916-17 



Strictly utilitarian lines and with its main purpose kept clearly in view, it 

 provides all the accommodation required at the moment without loss of 

 neatness or dignity. The materials for its construction were obtained in 

 Charlottetown and the building was constructed from original plans by 

 local tradesmen under the supervision of the officer in charge. 



CHARLOTTETOWN FIELD LABORATORY OF PLANT PATHOLOGY 



From a reference to the ground plan it will be seen that the principal 

 room, the laboratory, is of ample size, measuring 17 feet by 15 feet. It is 

 provided on the northern side with three large window^s, the sills of which 

 are flush with the bench for microscopic and cultural work which extends 

 along this wall. The work bench is more than 15 feet long, which is ample 

 for the accommodation of three technical workers, allowing each five feet 

 of desk room and a large window. Space is provided on a high bench 

 running along part of the west wall for sterilizers and incubators at one end 

 and for a sink and draining board at the other. Shelf accommodation for 

 apparatus, chemicals and cultures is found in a large glass cupboard at the 

 back of the laboratory on' the south wall. The room is lighted by means of 

 a strong electric drop-light near the ceiling, and numerous plugs are fixed 

 along both benches for microscope lamps, hot plates and sterilizers. 



The office measures 13 feet by 9 feet and is exceptionally well lighted by 

 four windows. There is space for a large bookcase which fits the recess 

 behind the door, a large writing desk and a typewriter desk, leaving room 

 for two workers, which is all that it will ever be called upon to accommodate. 

 It is separated from the main room by a partition which does not reach to 

 the ceiling, its height being only eight feet. This has the advantage of 

 allowing the heat from the stove in the laboratory to reach the office more 

 easily, and incidentally of adding to the apparent size of both rooms. A 

 partition wall of the same height separates the dark room from the labora- 

 tory on the east, and the cloak room, entry and cellar-stairway on the south, 

 but in these cases there is a concealed ceiling which shuts them off entirely. 

 The dark room has a window which can be closed by means of a hinged 

 shutter in which provision is made for lantern slide and projection work 

 through a smaller covered opening. The developing bench, which is three 

 feet high, is fitted with a sink, and the room is electrically lighted and ven- 

 tilated after an original plan so efficiently that it never becomes foul. 



The cellar extends underneath the whole of the building and has a 

 head room of six feet six inches. It is approached conveniently from the
