PROGRESS OF VEGETATION AND AWAKENING OF ANIMAL LIFE IN THE 

 MISSISSIPPI YALLEY DURING THE SPRING OF 1884 



This subject will be treated from the south, northward in steps or 

 sections of two degrees each, beginning with latitude 28° and extending 

 to latitude 53°, or over 25 degrees of latitude. Thus it will be seen 

 that the observations cover a tract of country 1,750 miles in length. 

 In studying each section the endeavor has been to make the dates in- 

 dicate fair averages for the middle of the section. For example, in 

 the section which extends from latitude 3S° to latitude 40°, the dates 

 are as exact as possible for latitude 39°. For the southern half they 

 would then be a day or two earlier, and for the northern part somewhat 

 later. It is also intended that the dates shall express average time ; 

 for instance, in the appearance of flowers, one observer, in a sunny and 

 well protected nook, finds the "first flower 7 ' while the rest of the coun- 

 try is bleak and bare. Another does not consider it proper to record 

 flowers as present until they can be found almost anywhere. In giving 

 dates of flowering, an average has been taken of the several dates re- 

 ceived, with a leaning toward the earlier. The same remark applies to 

 the other dates treated in this chapter. The number of observers in 

 the first five sections is so deplorably insufficient for the extent of the 

 country that the dates must be considered as the merest approxima-
