sequentlya more substantial enclosure should be decided 

 upon, the material would always be of use. 



The necessity for the thorough drainage of the entire 

 area of the park is very apparent. The peculiar char- 

 acter of its geological formation, renders its successful 

 drainage an interesting and perhaps a difficult problem. 



The deposits are composed of strata of sand, clay, 

 gravel and pebbles, in very irregular succession, and 

 showing little parallelism or uniformity ; in many places 

 the clay strata being very much distorted. The result 

 of all being a series of rounded hills, some of pure sand, 

 some of sand and clay, and others of pebbles and bould- 

 ers mixed with clay. In some instances channels seem 

 to have been formed by regular currents of water, while 

 in others deep valleys occur without any approximation 

 to regularity, unless their tendency to a bowl-shape be 

 so construed. The valleys have no outlets and the water 

 that falls into them either sinks through the soil or col- 

 lects so as to form pond holes. 



All of the depressions have been connected by a 

 series of levels which will enable me to lay down a sys- 

 tem of drainage which, while effective in removing the 

 surplus water from the soil will, it is believed, afford a 

 sufficient supply to enable its introduction with marked 

 effect in the general landscape. 



Besides the removal of the water which is palpably 

 evident in the form of deposits, thorough drainage, com-
