124 ORANGE CULTURE IN FLORIDA. 



to a salmon color with white spots. When half 

 grown, or about one half inch in length, two small 

 black wings are visible. When full grown, or three 

 fourths of an inch in length, two pairs of wings 

 show themselves, the smaller or under pair black, 

 the upper pair black, with salmon-colored marking 

 on the forward halves of the wings. When fully 

 grown the insect is ready for flight and is very ac- 

 tive. When young it is very busy feeding upon 

 small insects ; when grown it seeks for larger prey. 

 Since writing the above I find a description of the 

 above insect in Agricultural Report of 1875, page

The wood-louse, or white ant, has occasioned se- 

 rious trouble and sometimes death to many fine 

 young trees where the preventive was not used 

 ashes or slaked lime around the base of the trunk. 

 When a tree begins suddenly to show yellow leaves 

 examine a few inches below the surface at the base 

 of the trunk for wood-lice, especially if a stake has 

 been driven near the tree for its support, or if litter 

 from the forest or mulching of leaves has been used. 

 If wood-lice are discovered, clear them away care- 

 fully, and pour boiling water into the cavity around 

 the tree until all the cavities in which the lice could 

 have concealed themselves have been reached. If 

 the tree has been but partially girdled it will re- 

 cover, if the soil be placed above the wounded part. 

 But if the tree has been completely girdled, get 

 well rotted muck and pile it for three or four inches
