Questions on Poultry House Construction. 369 



are to be constructed later to be placed on different grades, the level 

 of the floor of each two pens being lower than the pens on the east. This 

 is the best method of placing poultry houses on sloping land 



.Where the house is built to conform with the grade of land, the 

 lower pens are colder than the higher pens because the cold air settles. 

 The litter also works to the lower part of the pen leaving the higher 

 portions of the floor bare. The appearance of such a house is very unsat- 

 isfactory to the eye. The house appears to be out of joint. The windows, 

 doors and all openings in front must necessarily be placed plumb, ana 

 cannot conform to the shape of the house. 



Q. 20. Should doors be placed in the front or on the side only in a 

 long housed 



Ans. 20. Doors are provided in front of each pen, the attendant enter- 

 ing each pen from the walk in front of the house. This is necessary in a 

 house intended for instruction purposes where each student has a pen. 

 The sill of all door openings is six inches above the floor to prevent the 

 litter from being- scratched out. On a commercial ranch there w'ould be 

 very little necessity for entering from the front, the work being done 

 through doors near the middle of each partition, the attendant passing 

 from pen to pen through the entire house. Where a trolley is to be used, 

 the double door swinging both ways on reversible hinges is highly desir- 

 able. Where trolleys are not used, a single door swinging both ways on 

 double hinges is preferable. A front door opening is convenient but not 

 necessary. Where the window swings on the side it can be used as 

 a door if required to receive and remove litter, and also for passage on 

 occasions where it becomes necessary, which is not often where the 

 attendant passes through from pen to pen. 



TRAP NESTS. 



A trap nest simple in construction, inexpensive and easy of operation 

 is here described, the plans, dimensions and description of which are here 

 given by which any person desiring to make the nest can do so. (Figs. 

 352, 353. 354, 355- 356.) It is not patented, and is presented to the public 

 as a contribution from the Department of Poultry Husbandry of the New 

 York State College of Agriculture at Cornell University.* 



Trap nests serve an excellent purpose in the hands of colleges and 

 experiment stations for instructional, investigational work. They are of 

 practical application and value only to a limited number of persons who 

 are engaged in commercial poultry keeping. Few poultrymen can afford 



*The trap nest device is an invention of R. C. Lawry, Instructor in Poultry 

 Husbandry at Cornell University.
