THIRTY-FOURTH FRUIT-GROWERS ' CONVENTION.

planted, and that is the Black Corniehon. It is very similar in shape 

 to the Emperor, ripens a little earlier, and is a heavy producer. It has 

 €ven a thicker skin than any of the other varieties of grapes, and for 

 this reason has always shipped well. 



There are other varieties which I might mention, namely, the Black 

 Morocco and the Gros Colman. Both of these varieties ripen later 

 than the Emperor or any other variety I have mentioned, but they 

 are little known ; and the only reason I can understand why they are 

 not planted more extensively has been, as some of the fruit men- have 

 told me. because the demand has never been as heavy in the Eastern 

 market for black grapes as it has for red. Otherwise there is no reason 

 in the world why such varieties as the Black Morocco and the Gros 

 Colman have not been planted extensively. They are very good pro- 

 ducers and ripen fully two weeks later than the Emperor. 



There are two new varieties, one called the Dattier de Beyrouth, also 

 known as the Risington. I predict a very great future for this grape. 

 It is sometimes on the form of the ]\Ialaga, only much larger, and has 

 the remarkable faculty of ripening almost at the same time as the 

 Thompson Seedless. It is a beautiful amber color, and in that respect 

 is far better than the Malaga. Another variety, which will probably 

 be extensively planted when it is better known, is the Sultanina Rosa. 

 That is the same as the Thompson Seedless. The true name is Sultanina 

 Rosa, not Thompson Seedless. That is a misnomer. The Sultanina 

 Rosa is identical with the Thompson Seedless, except instead of being 

 white it is pink, and it is a striking grape to be packed with the 

 Thompson Seedless. 



The Dattier de Beyrouth comes from Asia Elinor, and it is also 

 grown in Smyrna. 



PRESIDENT JEFFREY. I will say that the people of Lodi and 

 vicinity are literally riding in automobiles on the profits of their grapes, 

 and I don't see why you should not add that to your other industries 

 here. 



Now, we are going to have another lively time from now until a 

 quarter past four. Mr. S. A. Pease will read a paper on "Parasites and 

 the State Insectary. " 



PARASITES AND THE STATE INSECTARY. 



By S. a. pease, of San Beexabdino. 



The present status of parasitism means the value of the different 

 parasites, local and introduced, as proven by their efficiency or lack 

 of efficiency in the orchard or elsewhere to-day. California has had 

 a lively interest in parasites for our insect pests ever since the intro- 

 duction of the Vedalia cardinalis, parasite for the white scale {Icerya 

 purcJiasi) , in 1888. At the time of its introduction, the white scale 

 threatened the citrus industry of California. Thousands of dollars had 

 been spent in mechanical methods endeavoring to subdue the pest, but 

 with very poor results. The Vedalia proved master of the situation, 

 and in fifteen months from the time of its introduction had practically 

 cleared the field and given the orchardists renewed courage. Later,
