"The relation between the climate of any region, the growtli of vegetation, and 

 the quality of the crops is commonly understood to depend, primarily, upon the 

 actual temperature, sunshine, and moisture. The accumulated sums of these quan- 

 tities day by day after the seed is sowu hold a close relation to the resulting har- 

 vest. On the other hand, the seeds that have been raised for many years in sncces- 

 sion iu the same region have, by a process of acclimatization, attained the property of 

 yielding what may be called a normal crop under normal climatic conditions; hence 

 the departures of the weather for any year from the normal climate may be assumed to
