Olive trees fumigated.—In more than a score of 
instances in Southern California olive trees have been 
fumigated with the most satisfactory results. Trees 
which had not borne fruit for several years, after an 
application of fumigation, bore very heavy crops. 
The olive trees had been affected by black scale and 
smut which was totally destroyed by the application

fruit, not alone in flavor but also in size. Deciduous 
trees must be fumigated while they are dormant before 
the fruit buds or leaf buds begin to unfold or after the 
ripe fruit has been taken from the trees. This, in 
fact, we consider the best time to fumigate. Itisa 
serious blunder to neglect to avail one’s self of the 
advantages of fumigation in the belief that it is an 
expensive operation. Quite the contrary is the case. 
It makes but a small part of the orchardists’ expense 
while the benefits ramify in every direction.— 7he

Fumigation understood and appreciated.—A fumi- 
gated tree conserves its energy and produces clean 
fruit, having a brighter color and a better flavor than 
fruit which has gone through the process of washing 
and cleansing, and brings from 20 to 25 per cent. more 
in price in the market. The washing of oranges and 
lemons to remove black, purple, or red scale often 
breaks the skin and spoils the appearance and flavor of
