if applied lightly with a brash to the more, uardy plums, pears, and apples, espe- 
cially the latter, it can he used safely, especially if the trees arc cut hack to trunks 
and hases of Limbs. In the case of the apple I feel quite encouraged, believing that 
if used sparingly and evenly during winter and while a low temperature prevails it 
will save many trees that otherwise would have to be destroyed. 
After the publication of his September, 18!>7. circular, Professor Smith 
prepared a bulletin entitled u The San Jose Scale and How It .May Be 
Controlled," which bears date of November 27. 1897, but which was 
not distributed until late in January, 1898. The two following para- 
graphs from this bulletin summarize his present views : 
Apple, pear, quince, plum, cherry, peach, and a large variety of other trees were 
sprayed in August, and even the nursery trees came through the ordeal in safety in 
almost every instance, while in no case was any large tree killed cr even seriously 
wounded. In one instance hearing Kiefter trees were sprayed in July and Septem- 
ber and given heavy doses, with the result of killing ouly a few water sprouts. 
The essential points to he regarded in the application of kerosene are the finest 
possihle spray, the completest and thinnest possihle coating over the entire surface, 
and Aveather conditions favoring rapid evaporation. The trees themselves should he 
dry. Any departure; from these suggestions may cause injury, fori wish it distinctly 
understood that kerosene improperly used is fatal to plant life. 
Elsewhere he emphasizes the desirability of a more perfect atomizer 
than is now on the market, since the kerosene should be applied in the 
form of an almost impalpable mist. All trimming should In- done, 
according to Dr. Smith, at least a month before kerosene is applied. 
A clear dry day should be selected, so that the kerosene may evaporate 
rapidly. The trees themselves should be perfectly dry. If he were 
confined to one application only, he would select September treatment 
with kerosene as most likely to be completely effective. 
Mr. H. BT. Starnes, of the (Georgia Experiment Station, in an excel- 
lent bulletin published in October, 1897, quotes Dr. Smith mid Profes- 
sor Webster and announces the fact that he has arranged a scries of 
tests in different parts of the State, but gives no results. His remedial 
recommendations for Georgia districts are condensed in the following: 
"Two applications of whale-oil soap (2 to 2J pounds to the gallon, 
warm) a month apart in the fall — say the middle of November and 
December, respectively — followed by several kerosene sprayings 1 pari 
to 15) at intervals of two weeks in the spring." The kerosene spray- 
ings recommended are made by means of the mechanical mixture of 
kerosene and water with the "Weed kerosene tank.*' 
In North Carolina pure kerosene has been used to some extent. Trot. 
W. P. Massey, of the State Agricultural Experiment Station at Raleigh, 
informed the writer under date of January 10, 1898, that spraying with 
pure kerosene has destroyed the San Jose scale in more than one 
locality and no harm has been done to the trees. At K;iyet teville. in a 
nursery where there were two or three affected trees in the winter of 
1896-97, the owner is said to have sprayed the whole collection with 
kerosene when in leaf in May and did not kill ;i tree. 
From this rather full testimony (and more might be adduced from
