10. Common feeding floor not so likely to be used: The movable 

 houses are not likely to be attached to the floor for feeding and because 

 it is somewhat troublesome to move them to the floor, the tendency would 

 be to feed on the ground. 



11. Dfinger greater ichen grouped: Huddling and piling up is to be 

 carefully guarded against when several individual houses are assembled 

 in a common yard; under such circumstances the hogs tend to crowd 

 into a few houses rather than to distribute themselves evenly among all. 



12. Secluded sicine fight more when herded: Isolated swine, especially 

 sows, when turned together quarrel considerably, resulting in various 

 injuries, loss of flesh, and sometimes death. 



13. Sanitfition may he discouraged: Masonry construction which has 

 much sanitary merit is precluded from the materials used for building. 

 The removal of manure from the houses to the fields, other things being 

 equal, is more likely to be neglected in that it is a greater task to 

 gather it from several sources than one. Steel rail litter carriers are 

 not practical in small houses. 



14. Equipment usually larger: To facilitate the work of feeding and 

 watering, a horse and low wagon, or stone boat with its extra barrels 

 or tank is quite essential, especially when the houses are widely dis- 

 tributed. 



15. Advertising value less: The general appearance of a few, or 

 even several individual houses, is not so impressive as that of the more 

 elaborate, centralized house or a combination of the two types. 



TYPES Oi" MOVABLE HOUSES WITH DESCRIPTION. 



A large number of movable houses have been erected by the animal 

 husbandry and agricultural engineering sections. Many of these differ 

 simply in the arrangement of doors, shade lifts, ventilators, and win- 

 dows. It is unnecessary to describe all of the different houses investi- 

 gated, but the details of construction of six distinct types with sug- 

 gestive modifications is given here. 



These houses have proven satisfactory in general service, but the 

 special adaptations of the different types are dependent upon local 

 conditions. 



The movable types of which photographs are shown, specifications 

 drawn, working drawings presented, etc., are: 

 I. Iowa Gable Roof House. 

 II. Ames Combination Roof House. 



III. "A" House — (Doors Hinged at Side). 



IV. "A" House — (Doors Hinged at Top). 

 V. Tepee House. 



VI. Economy House. 



THE IOWA GABLE ROOF HOUSE. 



The Iowa gable roof house has for many years been successfully used 

 by the Iowa Agricultural Experiment station. It is simple of construc- 

 tion and presents a very attractive appearance. (See figs. 1, 2, 3, 4, 5, 6, 

 7 and 8.) Some of its good features are: The perpendicular walls 

 enable the floor space to be utilized to good advantage, permit of shade
