ARRANGEMENT OF HOUSES FOR CONVENIENCE AND FOR 



LIGHT 



In buying an established range, one must take houses 

 as they are found. In the larger number of cases, ranges 

 have been established some time, and the houses exhibit 

 a peculiar arrangement. As additional room has been 

 needed, a house has been " tacked on " wherever it has 

 been found possible to place it. It puzzles a visitor to find 

 his way about such a range. In the care and upkeep of 

 such houses, many unnecessary steps are taken and 

 much valuable time is wasted. 



47. Arrangement for convenience. (Fig. 6.) Ex- 

 tremely long houses often make it necessary to travel 

 long distances, and their management is not always 

 economical. In modern ranges there is usually some sort 

 of a connecting house, and growing houses lead from this. 

 The connecting house is narrow and serves as a thorough- 

 fare for workmen. Heating mains usually extend through 

 these houses. They are quite frequently used for prop- 

 agation. The connecting houses are variously placed. 

 Sometimes they run through the center of the range, and 

 again they may be at either end, as best suits the conven- 

 ience of the location. The connecting houses should be 

 low enough so that light is not shut off from growing 

 houses. Usually the alley-houses simply serve as a con- 

 necting passage between the larger houses, but in case 

 they are placed in the center of the range and crops re- 

 quiring different temperatures are grown in the houses on 

 either side, partitions frequently are run through these 

 houses, thus making the alley-house continuous. Such 

 partitions should be avoided wherever possible, for they 

 are detrimental to the best light conditions.
