BOARD OF HORTICULTURE 



grown luxuriantly on the site in question, you coukl not ask a hetter recommenda- 

 tion as to soll, climate or elevation. As to rieh soil profluein;; too much wood 

 growtli. I believe tliat, witli tlie proper pruning to force out fruitiug laterals, tliere 

 caniiot he too much wood growth. 



As to elevation, again the best test is the presence of the liazel. If the hazel 

 will mature any nuts in the locality in question, it is not too high for the filhert. 

 And the filhert has one great advantage. along with the walnut, for mountaiuous 

 and inaccessible localities where transportation is intermittent, in that it is not 

 rt perishable crop but can be stored for months without injury, as well as being 

 a concentrated crop. of high value per pound, thus being able to stand the cost 

 of expensive hauls to the railhead. 



Varieties 



The choiee of varieties is next in importance. Due to the fact that the filbert 

 is not self-fertile, two elements demand consideration, one of yield, the other of 

 pollenation, which will be considered more in detail under that head. 



There is no question whatever that at this time the Barcelona is the only uut 

 for the main planting, from a commercial Standpoint. I believe everyone will 

 agree with me when I say that a commercial planting is for results in doUars and 

 Cents only, and the aesthetics have little place therein. The Barcelona is a true 

 commercial nut to begin with. of good size and readily saleable ; it has a very 

 Short husk which opens as it matures and permits the nut to fall to the ground, 

 while the husk remains on the tree for some time in most cases. Those good nuts 

 which mature late and to which the husk still clings can be easily freed of the 

 husk by drying for a few days and beating. It is the heaviest yielder of all the 

 filberts so far introduced into this country. And it is free from the attacks of 

 the bud mite, the only insect pest which bothers the filberts. 



The DuChilly is a fine nut, but it has the disadvantages of being an irregulär 

 yielder, has a long husk which must be removed after the nuts are gathered. and 

 is subject to the bud mite, any one of which is enough to condemn it for the main 

 planting. But it is very valuable as a pollenizer for the Barcelona, and for that 

 reason should have a place in every commercial planting. 



The Daviana is a very fine nut but is an extremely light yielder at present 

 and has the other disadvantages of the DuChilly. It is a vigorous grower and 

 makes a big tree. It is valuable at present, from a commercial standpoint. only 

 as a pollenizer for the DuChilly. 



The White Aveline is a good yielder, considering the size of the tree, which is 

 smaller than the Barcelona and DuChilly, and has some value as a pollenizer for 

 these varieties. But it has an extremely long, clinging husk and until some one 

 invents a machine husker it most decidedly has no place in the commercial 

 planting. other than as a pollenizer. It is also subject to the bud mite. 



The Red Aveliiie is a very weak. scraggly tree, and its prineipal value is to 

 pollenize the White Aveline. But as this is accomplished by other varieties 

 included, I would omit it entirely from a commercial planting. 



There is a number of other varieties which have had no extensive tryout — 

 the Cosford, Grosse Blanche, Chaperon. Clackamas, and others. I am sorry I 

 have no first-hand knowledge of these varieties and can say nothing about them. 



Pollenation 



Pollenation is undoubtedly one of the most important Problems that confront 

 the filbert grower. Up until the past year no intensive work has l)een done to 

 solve it. However, the Oregon Agrieultural College has taken it uji and last 

 season band poUenated al)out 2,200 blossoms in our groves and intend, during the 

 Coming season, to carry on the work in a number of groves. Due to the cold snap 

 last Winter just before the blossoming perlod, which injured the poUen to a con-
