The red spider has got in its work and left many half-stripped trees, 

 where they have not dusted with sulphur. 



In many orchards where spraying had not been done I found a large 

 increase of scale, showing whatever had been working on them during 

 the last two or three years had not kept up the work, or had lost their 

 appetite for scale. 



Yours, G. M. GRAY. 



Palermo, October 29, 1894. 



To the Honorable State Board of Horticulture: 



Gentlemen: I herewith forward to you my report of work as Horti- 

 cultural Commissioner of the district lying east of the Feather River, in 

 Butte County. 



There have been inspected one hundred and ninety orchards, and 

 sixty-four were found infested with pernicious scale. The most of them 

 were sprayed with lime, sulphur, and salt. Those that had been 

 sprayed the year before showed a decrease of scale, but were sprayed 

 again this year. 



In Oroville two hundred and nineteen places set to citrus fruit trees 

 were inspected; one hundred and ninety were found to be infested with 

 soft brown orange scale; forty with yellow, and three with black scale. 

 The yellow and brown scales are on the increase. 



At Palermo the brown scale is all that is troubling the citrus trees. 

 Most of the groves were sprayed last spring with whale-oil soap. There 

 was one case of orange trees from Florida received at Palermo, infested 

 with purple scale. These were quarantined and gased until all the eggs 

 of the scale were destroyed. 



Some orange trees were received from the southern counties, with 

 live black scale. They were held, and disinfected, and watched until 

 all scale and eggs were dead. 



In one consignment of deciduous trees from Oregon, the peach stock 

 was infested with Eastern peach-root borer; all were burned. 



On nearly all shipments of deciduous trees received in this district 

 root knot was found to a greater or less extent; all trees thus affected 

 were destroyed. 



The pear leaf blister mite, a new pest, made its appearance here last 

 spring upon pear trees. Dry sulphur was used, but I am not able to 

 report the result of its use. 



Respectfully submitted. 



EBEN BOALT, 

 Horticultural Commissioner. 



SAN DIEGO COUNTY. 



To the Honorable State Board of Horticulture: 



Gentlemen : We present you herewith a partial report of the con- 

 dition of the fruit interests of this county, with partial statistics. 



It is probable that high-water mark in tree planting in this county 

 was reached last year, as indicated by the enormous area of 2,390 acres
