Napa Convention. — The Forty-ninth Annual State Fruit Growers' 

 C(;nvention. will lie held on the 15th, 16th, and 17th of Xoveniber. 

 On the 13th and 14th — the two days preceding — the regular conven- 

 tion of the State Association of County Horticultural Commissioners 

 will meet. 



It is expected that most of the time of the convention will be given 

 over to the discussion of marketing and allied topics. Contemplated 

 horticultural legislation will also be discussed fully, and a report will 

 be made by a large committee of prominent fruit growers, shippers, 

 nurserymen and others, who have been giving this matter the most 

 careful attention. 



A special feature of the convention will be an extensive exhibit of 

 farm tractors, tools, spray machinery, etc. Twenty-five acres of land 

 have been secured for tractor demonstration purposes, and it is 

 expected that the leading makes of farm tractors will be on exhibition. 

 An effort is being made to secure a Henry Ford tractor wliieh is at 

 present in an experimental stage. 



An important feature will be a basket picnic under the direction 

 of the County Farm Bureau. This will take place at noon during 

 one day of the convention, and will be attended by farmers and their 

 invited guests from all parts of the county. 



County Horticultural Commissioner Fox, of Napa, is working hard 

 to make the convention the best that has ever been held in the state, 

 and it seems probable that his efforts will be rewarded. — G. P. W.
