The Grand Prize, 

 the highest award, 

 bestowed upon Ghirardelli's 

 Ground Chocolate by the 

 Panama -Pacific Exposition, 

 San Francisco 1915, is an 

 additional testimonial to its un- 

 questioned supremacy. The expert

the very qualities that have made it a house- 

 hold favorite on the Pacific Coast since it 

 was originated by D. Ghirardelli in the 

 early seventies. Not to know — and what 

 is more, not to use — Ghirardelli's Ground 

 Chocolate, is to be unmindful of health, 

 economy and the appeal of a wholesome 

 appetite.

lar ill outline. In some cases the migra- 

 tion of the bacteria can be noticed 

 along certain veins in advance of the 

 general border of the dead area. All 

 stages of leaf invasions have been 

 found from slight marginal infec- 

 tions to 'isions which have advanced 

 throughout the entire leaf blade and 

 down the petiole. These leaf infections 

 were not rare, l)ut it was possible to 

 find dozens of them on a single five- 

 year-old tree. The writer is of the 

 opinion that the bacteria enter the in- 

 tercellular spaces through the water- 

 pores and also by the stomata to some 

 extent, and later penetrate the vessels 

 in the way suggested by Bachmann. It 

 remains for further investigation to 

 definitely substantiate this view. It is 



an easy matter to verify the presence 

 of the bacteria by microscopic exami- 

 nation. Dissections made from the ad- 

 vancing edge of a lesion give the 

 organism in large number, and if the 

 tissue selected includes one of the 

 larger veins they can be seen to ooze 

 out from the broken ends of the ves- 

 sels. A sulTicient number of lesions 

 have been examined to leave no doubt 

 as to the constant presence of the bac- 

 teria. The lesions have also been tested 

 by cultures for the presence of living 

 bacteria. Mr. H. W. Samson, Horticul- 

 tural Inspector at Spokane, assisted in 

 collecting material and also sent fresh 

 specimens to our laboratory for use. 

 It was at his solicitalicm that the writer 

 first visited Spokane to make field 



June 



observations. In many of the isolations 

 tried the bacteria were found to be 

 dead, but pure cultures were obtained 

 from others by the poured - plate 

 method. Since the study of these leaf 

 lesions was not begun until Jul>-, this 

 condition is what one would expect, 

 as at this time of the year tbe bacteria 

 are dead in a good per cent of the twig 

 infections. In some cases where micro- 

 scopic examination showed an abun- 

 dance of l)acteria, the cultures showed 

 that only a relatively small per cent 

 were alive. It seems probable that a 

 certain per cent of the leaf lesions will 

 behave like the twig lesions, and the 

 bacteria become active in them after 

 the return of more favorable condi- 

 tions. The pure cultures isolated from 

 the leaf lesions have been used for 

 making inoculations into seedling apple 

 trees. The trees to be inoculated were 

 placed in the inoculation chamljer and 

 kept well watered for 48 hours pre- 

 vious to introducing the bacteria into 

 the tips just iiack of the terminal bud. 

 The inoculations were made .luly 31st, 

 and by August 8th the seedling ex- 

 hibited fire blight in severe and typical 

 form. The microscopic examinations

TARRED ORCHARD YARN 



The time is now just right for tying fruit 

 trees. Tie the interior of the tree before the 

 leaves are out and the exterior can be tied 

 later. Orchard Yarn is put up in 5 lb. balls, 

 10 balls to a sack. This form is more conven- 

 ient for use as the ball can be placed in the 

 tree and by pulling the yarn from the inside 

 it never tangles. 2-ply contains about 100 

 feet per pound.
