flattened appearance, half-hard shell of clear color. The shell is well 

 filled and its kernel of good quality. The tree is vigorous, fruitful, 

 portly and erect. The nuts mature late ; they are harvested in October. 



Noix a Cerneau Rouge. The Noix a Cerneau Rouge (Juglans regia 

 rubra) is an old variety. It is mentioned for the first time (1763) 

 by the Dutch pomologist Knoop and afterwards pointed out by various 

 others. This variety was completely lost sight of. It has been recog- 

 nized after twenty years at Gratz (Styrie), where there is a good 

 specimen. 



The nut is rather large, of ovoid form, having a shell half -hard, 

 very dented and well filled. The kernel, as in many varieties of 

 hazelnuts, is covered with a blood-red or carmine-red membrane ; it is of 

 good quality. 



The tree is identical with the Noyer Commune and possesses the same 

 vigor. It is reproduced sufficiently well from seed and bears before 

 the eighth year. This information was obligingly furnished by M. 

 Jouin, director of the Simon-Louis nurseries at Plantieres near Metz. 

 This is established by noting down information from those who have 

 grown the Noix a Cerneau Rouge. 



ACKNOWLEDGMENT. 



In the eight or nine years, during which the observations and investi- 

 gations reported in this bulletin have been under way, numberless 

 suggestions, ideas, and bits of information have been obtained from a 

 great many different people, some of whom have been mentioned in 

 the body of the publication in connection with various subjects. It 

 is impossible, however, to give full individual credit for everything of 

 this sort. We can only say, in general, that almost all of this informa- 

 tion is the result of continued observation, correspondence, and con- 

 versation carried on from year to year in all parts of the State where 

 we could learn of any possible source of information concerning wal- 

 nuts. To all of those who have so willingly helped us during this work 

 we wish to express our most sincere appreciation. To Messrs. S. F. 

 and Frank A. JJeib, of San Jose, W. W. Fitzgerald, of Stockton, and 

 J. B. Neff, of Anaheim, we feel especially indebted for many sugges- 

 tions and ideas which could not be individually credited in the bulletin. 

 Special mention is also due to Mr. Edgar A. Metcalfe, our expert propa- 

 gator, who has worked out many of the ideas contained in the bulletin, 

 especially those upon budding the walnut. The majority of our sug- 

 gestions upon propagation have come from the work of Mr. Metcalfe 

 and that of Mr. George Weinshank, of Whittier.
