3 The San Jose Scale in Japan. 



■districts, although sometimes it is very conspicuous, together with Parlatoria. 

 It is said in some localities the scale once did great damage to the fruit trees, 

 and they were treatel with kerosene very vigorously ; after that the scale did 

 not spread to so great an extent as to do actual harm to the trees. 



5. Fukushima-hen. 



The scale has heen found in 2 localities, Fukushima and Wakamatsu 

 cities. An orchard, near Wakamatsu city containing several hundred apple 

 trees, was completely mined by the scale and by trunk borers ; many trees 

 were blown down by a s-vere wind some years ago, so the owners thought it 

 best to remove the poor trees and plant pear trees instead of apple, and also 

 to plant pears among the apples. When the writer visited the orchard last 

 fall, he advised the digiring up and burning of the trees, and the owners promised 

 him this should be done. The apple trees were obtained from Niigata in 1887. 



A pear orchard near the apple plantation was free from the San Jose 

 Scale, although Parlatoria and other scales were not uncommon. 



6. Miyagi-Jcen. 



Near Miyagi city the writer found the scale on pear and apple trees ; an 

 orchard contained about 5')0 trees of 10 years age, the stock having come 

 from Yamagata ; a pear orchard at Nanai-village contained 5,000 trees of 10- 

 15 years age. Many of f.he trees of these orchards were attacked by the 

 scale. The writer particularly noticed a tree about 8 years old, and cut off 

 about -1 ft. above the grounl, and grafted on the top, protecting the grafts 

 with straw ; the trunk mid.^.r the straw was so thickly covered with the scales 

 that it was difficult to see the bark of the tree, but on the young grafted 

 shoots there were but very few scales. 



In the yard of the agricultural school near the city also there were several 

 apple and pear trees among other fruit trees ; these pear trees about 10 years 

 old were of an American veriety infested by the scale. In Mr. Hayakawa's 

 orchard near the city, the scale was also found together with Parlatoria to 

 some extent.
