JLesson xxxni.] SEASONS. 



then its axis will always be parallel to itself, and 

 the various seasons will be represented in the 

 different parts of the path. Thus, when the globe 

 is at one of the places where the hoops intersect, 

 its poles are equally illuminated, and the days are 

 every where of the same length : then Spring 

 commences to the inhabitants of the northern 

 hemisphere; being about the 9Oth of March. 

 As the globe is carried on r the days keep increas- 

 ing, until it has arrived at the lowest part of thft 

 hoops ; when the north pole will appear a con- 

 siderable way in the illuminated hemisphere, and 

 the south pole as much in the darkened one ; then 

 is our beginning of Summer and their beginning 

 of Winter ; and here it may be perceived that any 

 parallel of latitude toward the north pole is 

 considerably more in the enlightened hemisphere 

 than in the darkened one; while, on the con- 

 trary, in the southern hemisphere, a far greater 

 part of the parallel of latitude is darkened than 

 enlightened: hence, our days are then longest* 

 and theirs shortest; which happens about the 

 21st of June. The globe being carried on until it 

 arrive at the intersection of the hoops on the other 

 side; each. of. its poles is again illuminated, and 

 the days every, where of equal length^ because 

 each parallel of latitude is half in the enlightened 

 and half in- the darkened part^ then 'Commence* 

 Autumn with us, being about the 22el. of Sep- 

 tember. As the globe is- carried oa> the days 

 with us shorten, until it has-arrived at the highest 

 part of the hoop : then the north pok is in th
