EXPERIMENTAL FARMS 



1-2 EDWARD VII., A. 1902 



on the sea-girt islands in parts of South America this material is very rich in plant 

 food, which is in readily soluble forms and the quantity deposited every year would 

 probably be sufficient to supply a considerable part of the small proportion of these 

 elements needed for healthy tree growth. Traces only of these useful elements are 

 found in the clear, pure sand which covers so large a part of the surface of the island, 

 probably for the reason that this fertilizing material if not promptly taken up by plant 

 roots is so soluble that it is soon washed through the porous sand by frequent rains and 

 its accumulation is thus prevented. 



CONDITIONS OF CLIMATE — STRONG WINDS. 



The climate is a very singular one, and one of the chief difficulties in the way of 

 rapid success in tree planting is the force and constancy of the winds, and the fre- 

 quency of the gales. From the meteorological tables here given, prepared by Mr. W. T. 

 Ellis from material kindly furnished by Mr. R. F. Stupart, Director of the Meteoro- 

 logical Service of Canada, covering nearly four years, it appears that the average 

 hourly velocity of the wind during the whole of that period has been more than 18 

 miles, while the gales have averaged over 10 each month when the winds have ranged 

 mostly from 40 to 65 miles an hour. A study of the temperatures will show that there 

 are no extremes of heat or cold on the island ; that the highest temperature during the 

 past four years has been 78, and the lowest point reached by the thermometer during 

 the same period was 5 above zero.
