extremity of the track, fpots whofe length do not exceed their 

 breadth. 



Obs. 4. The regularity with which thofe two tracks run pa- 

 rallel and near to each other, is not more wonderful than is the 

 correfpondency that is in general to be obferved with regard to 

 the conftruclion of thefe, as confifting either of a continuous 

 track or of feparate pieces ; and to fo great a degree is carried 

 this refemblance of the two tracks, that, where it is by fpots 

 the tracks are made, there the fimilarity, even of the fpots, 

 were fometimes remarked, fo that it feemed as if the one had 

 been a copy of the other. 



Obs. 5. Besides the brown colour of thofe new made tracks, 

 which might be feen at a considerable diftance, (two or three 

 hundred feet), there was another (tripe of a dark green, which 

 might be feen at a ftill greater diftance. Upon more clofe exa- 

 mination, this laft appearance was found to take its origin in 

 fome grafs of a very dark green, which, in fome places here 

 and there of the laft year's track, began to grow in the black 

 ground and among the rotten grafs ; but the greateft part of this 

 deep green was behind the laft year's track, and was evidently 

 owing to a fimilar growth of graffes in places which had been 

 formerly killed or withered, and were now almoft covered with 

 new plants, which gave a deeper ihade of green than the reft of 

 the hill. 



This laft obfervation led to another ; for here a queftion na- 

 turally occurred, That, fince this fucceffion of things had cer- 

 tainly taken place at leaft three years, how many fucceftive 

 tracks might be detected from the examination of thofe appear- 

 ances ? With this view I confidered attentively fome places 

 where the marks were moft diftincl:, and could plainly count 

 five or fix fucceflions ; the number cannot be accurately afcer- 

 tained, becaufe thofe which have been made above three or four 

 years are much effaced, although the colour, and fome other 

 marks, evidently prove, that there had been feveral more.
