FIFTEENTH ANNUAL YEAR BOOK— PART X 737 



THE ECONOMY HOUSE. 



One may easily, quickly, and with moderate cost construct the Economy 

 house. (See figures 32, 33, 34 and 35.) Many of the excellent features of the 

 more elaborate and complete house are Included. 



The most convenient and handy of all the houses presented is the Economy, 

 built at a cost of not to exceed $8.00 for material. We have here a most suc- 

 cessful house from the standpoint of economy. Figuring on a total cost of $10 

 for each iTOuse, same to include lumber, hardware, paint and labor, and allow- 

 ing an average service of ten years we have a depreciation of $1.00 per an- 

 num. Counting the interest on one-half the average value, or $5.00, at 5% 

 .makes an additional cost per annum of 25c; in addition we may include up-keep 

 , charges at 25c, mak-ing a total of $1.50 annual cost. During the year such a 

 house should shelter the equivalent of four sows with litters following, at an 

 average cost to the sow with litter of $.375, or assuming that seven pigs are 

 raised to the litter we have a cost of a little over 5c to the weanling pig, — a 

 most reasonable charge. 



The Economy is built of small size, being of 5'x7' floor dimensions. The 

 somewhat expensive floor which has been built in the other houses, although 

 optional with the builder, has not been included. Because of the absence of 

 wooden floor the location should be dry, and preferably quite high. The house 

 will shelter a reasonable large sow with litter. 



In providing sheltering and farrowing facilities the Economy has a wide 

 field of usefulness. When it becomes necessary to furnish protection for the 

 sow that farrows unexpectedly in the pasture or field, far removed from the 

 central buildings, the small Economy is handy. 



For the admittance of sunlight the east side roof, the entrance door being on 

 the south, has a roof door hinged at the side. A small rear door is furnished 

 for convenience to the attendant and to provide additional ventilation if needed. 

 The ventilators under the comb of the roof provide systematic and ample aera- 

 tion for general purposes. 



The front end doorway may be provided with a simple top hinged door if it 

 is deemed necessary. On this small house the door may be dispensed with, al- 

 though its addition has obvious advantages. 



THE CASE OF THE METAL HOG HOUSE. 



The persistent high price of lumber has encouraged some manufacturers 

 to place a metal hog house upon the market. At the present time it 

 is quite widely advertised in the farm press, and a considerable number 

 are being sold in this state. 



These questions have become important: Is the metal house satis- 

 factory? Does it possess the essentials of an ideal hog house, and if 

 not, wherein does it fail? 



To learn of the relative warmth and range in temperature within 

 the standard wooden as compared with the new metal "A" houses a 

 series of experimental tests was conducted. The wooden houses used 

 were of the same general type and size as the metal ones, thus making 

 the comparison fair and trustworthy. Table I gives a general idea of 

 the floor size, capacity, and outside area (divided so as to show the 

 entire as well as the east and south surface areas) of the houses com- 

 pared.
