Tree No. 1. 
August 15. — Cut down to three feet from the ground and budded; 
good shoots from buds. Bark covered with thick scale, variety known 
as hominy scale, color gray-ground speckled with white; nowhere is 
the bark visible. This scale has resisted everything applied to it. Ap- 
plied one part of murvite to five parts water. Ten minutes after appli- 
cation the scale was found to be loose ; it was wiped off with a wisp of 
dry grass, with but little force. The bark was found to be green but 
ridged. After cleaning, the tree had a healthy appearance ; w T eather 
hot. This and surrounding trees had been highly manured ; soil good 
pine land, a little wet, ditched. 
Mr. Hubbard classified the scale as Parlatoria pergandii. It was 
covered by a fungoid growth that matted the whole together. The 
capsules of the fungus X found were the white spots, the general color 
being gray. 
August 23. — Tree thriving. 
September 8. — Tree has made heavy, healthy growth. 
October 25. — Tree still growing. 
Trees Nos. 2-5. 
August 16. — Tree No. 2 is in a well cultivated, highly manured, young 
grove of very thrifty trees, on fine land, thoroughly drained ; its trunk 
is 4 inches in diameter at the ground; diameter of head 6 feet ; height 
8 feet; has lost about one-half of its branches by M. gloverii. To#k 
samples inside and sprayed with a solution of one part murvite to fiye 
parts water. Eeturned one hour afterward and threw a stream of wat£r 
on the scales from a good force pump. The scale was readily washed off 
the young, smooth bark, and much was washed from the rough, older 
bark, but not all. A greater force would clean off all the scales. The 
scales washed turned bluish white in color. 
Three other trees near by, similarly infested, were sprayed: No. 3 with 
solution 1 to 10, No. 4 with 1 to 20, No. 5 with 1 to 30. No water was
