Ap. 19. Trees 4-7. The petroleum is well distributed and is quite evi- 

 dent. Trees 15-19, 25-28,41-49 are about as 4-7 except that the buds 

 are starting, and that the petroleum is very abundant on trees 48 and 49, 

 and is quite evident on tree 22. 



May II. Tree 22 is very hard-looking, but the leaves near the tips 

 of the twigs are nearly out, and there are a number of blossoms opening. 

 Tree 25. One branch has relatively few leaves which are out. The othec 

 branches are dead, probably from the effects of the scale, which was ex- 

 ceedingly abundant. This tree was a very bad-looking one to begin with. 

 Trees 26-28. The leaves have started well, and the blossoms are be- 

 ginning to appear. Trees 41-47. Many of the blossoms have come out, 

 the leaves are appearing. The trees are oily and can be distinguished 

 from the others at some distance. 



May 14. Trees 4-7 are apparently unharmed by the petroleum, which 

 shows well. Tree 5 has (luite a number of blossoms out and the leaves 

 are just starting. Tree 7. The leaves are well out and the blossoms are 

 nearly past. Trees 15-19. The leaves have started well and the blos- 

 soms are numerous, except on trees 17 and 18, which are a different 

 variety. The full bloom and starting leaves of tree 15 are shown in pi. 9. 

 On tree 22 the leaves are rather thin but they are pretty well started. 

 There are only a few blossoms. Several suckers have appeared. The 

 scale on tree 25 was very bad, and the leaves have appeared on but one 

 short branch. Blossoms are nearly out and are abundant on trees 26-28. 

 The leaves are rather plenty and pretty well developed. Tree 41 has 

 many blossoms and small leaves. Trees 42-45 and 47. The numerous 

 buds are partly opened and the leaves are starting. On trees 46 and 48 

 the leaves are well out. Tree 49. The leaves are about half out and 

 the numerous blo.ssoms are nearly past. 



May 28. The leaves of trees 22 and 25 are rather scarce, small and 

 pale. Both trees were very badly infested. Trees 48 and 49 are healthy 

 and the leaves are abundant. Tree 5 presents a ragged appearance, and 

 several limbs have failed to develop leaves. 



July 2. There are apparently no living young scales on trees 4-7, 26, 

 27, 46, 48 and 49. .\ very few are found on trees 15-19, 28, 29,41, 42, 

 44 and 45. They are somewhat abundant or numerous on trees 22, 43 

 and 47. 



Aug. 3. Very few or no living young are found on trees 15-19, 41- 

 49 and comparatively few on trees 4-7 and 22. 



Sep. 7. Very few or no living young are found on trees 5, 6, 18, 19, 

 ?^- ""y, 48 and 49. A few living young occur on trees 7, 16, 17, 25
