appears in summer and in winter, by placing two pictures side by 

 side which have been obtained in each season respectively. These 

 should be taken from the same distance and the same place, the 

 spots where the legs of the tripod rested in the first case being 

 marked by pegs driven into the ground as before suggested (Part I, 

 Chapter XIV). 



It will not be found quite such an easy matter as may be 

 imagined to discover trees which can be photographed quite free 

 from their surroundings and in such a way that their whole outline 

 is perfectly seen. A park especially where the lower branches of the 

 trees have not been removed should be sought for. Some very good 

 pictures have been obtained in Windsor Forest, while Kew Gardens 

 will prove useful to the dweller in London, although the trees in 

 the latter spot are planted, so very closely together that some 

 difficulty will be met with in making a choice of subjects.
