Factors of Location Affecting Production. A mild temperate 

 climate is ideal, although poultry is managed successfully under 

 a great range of climatic conditions. Factors of temperature 

 should receive careful consideration. Extremes should be avoided, 

 and locations which are characterized by rapid variations are 

 undesirable. In the southern part of the United States, where 

 average temperatures are high, conditions are less desirable than 

 in the more temperate climates farther north. Canadian condi- 

 tions, although very cold, seem to be superior to the extreme 

 torrid climate of the South. There is no one best latitude; ideal 

 conditions will usually be found in the latitude of Massachusetts, 

 New York, New Jersey, Ohio, Indiana, Missouri, and through

to the Pacific Coast. The prevailing wind direction should be 

 determined, and the character of weather which it brings will 

 materially affect climatic conditions. Prevailing winds from over 

 the land are most desirable, as the associated climate is usually 

 dry. North to northwest winds are best. Atmospheric conditions 

 should also be considered. Close proximity to large bodies of 

 water, to low river valleys, or to the ocean usually means a rela- 

 tively high humidity, which is undesirable. For example, the 

 Jersey coast, being close to the Atlantic Ocean, is hancticapped 

 by the presence of thick fogs during spring and fall, which means 

 the prevalence of considerable roup and canker during these 

 seasons, while central New York State or North Jersey, being 

 removed from the water, has a drier climate and less trouble from 

 atmospheric moisture.
