fitted for potatoes, but a strip along 

 the rail fence on the south side, 150 

 feet wide, had been allowed to remain 

 on account of the better stand, and on 

 this area, as was usual generally, the 

 number of plants increased as the 

 fence was approached. To the west 

 of this same field there was another 

 of timothy, and adjacent to this there 

 was a strip of oats 200 feet wide where 

 the stand of plants was markedly bet- 

 ter than farther away ; and the same 



injured and the clover had been en- 

 tirely killed out. 



In figs. 2 and 3 the condition of 

 crops which were observed on other 

 fields, and the surroundings which 

 produced these differences, are also 

 shown. 



In fig. 2 the southeastern field is 80 

 rods long and 30 rods wide. Here it 

 will be seen the oats were good along 

 the road in the lee of the two fences, 

 40 per cent, gone further away, and

fact was observed in an adjacent field 

 lying to the east of a closely fed pas- 

 ture free from trees and shrubs. In 

 another field 120 rods long from north 

 to south and 80 rods wide, seeded to 

 oats and clover, the effect of the sur- 

 roundings upon the crops is indicated 

 in fig. i, where it will be seen that at 

 a certain distance from the conditions 

 which have influenced the tempera- 

 ture, humidity, and velocity of the 

 wind, the oats had been verv much 



entirely destroyed on the eastern half. 

 Further north the field of oats adja- 

 cent to the field of grass and with 

 woods to the north and in the distance 

 to the west, had a good stand of plants, 

 being seriously injured only at the 

 south, where the wind came through 

 between the two pieces of woods along 

 the course indicated by the arrow. 

 Similarly, in fig. 3, the influence of 

 shelters are clearly and sharply 

 brought about by the condition of the
