Rosebiirg it has spread along the Roseburg-Myrtle Point route over the 

 mountains to within ten or twelve miles of the latter place and is re- 

 ported in several orchards about there. It is also reported in orchards 

 about the headAvaters of Coos river, having probably advanced from 

 orchard to orchard along the wagon road from Roseburg to Coos Bay as 

 it has along the Roseburg-Myrtle Point route. 



It seems evident that the reason for the present immunity from codling 

 moth ravages in the orchards of the Coos Bay region is not far to seek. 

 On account of its geological conformation, the highways leading to this 

 region mostly follow the windings of the streams in and out among the 

 timber-covered mountains. The orchards, mostly home orchards, are lo- 

 cated here and there along the highways in little valleys or pockets be- 

 tween the mountains, often at considerable distances apart. Each orchard, 

 or little group of orchards, is therefore protected by a natural barrier of 

 timber and mountains, practically insurmountable to the codling moth 

 unless it be carried over or around it by human agencies. 



I believe the idea that climatic conditions are responsible for the ab- 

 sence of codling moth injury has been decidedly harmful. It has car- 

 ried with it the idea that no effort is necessary to keep the orchards free 

 from this, the greatest apple pest. I believe that by a rigid system of 

 orchard inspection put in operation a few years ago along the highways 

 leading from Roseburg to Myrtle Point and Coos Bay, and a rigid quar- 

 antine of infested fruit, that it would have been possible to exclude the 

 codling moth from this entire region for years to come. It is probably too 

 late now. Still there are undoubtedly many isolated orchards in which 

 it is not yet found and which can be kept free from its ravages for years 

 by a little effort. The utmost care should be taken to prevent its intro- 

 duction into such orchards either in infested fruit or in the packages in 

 which such fruit has been packeo. 



So far as the codling moth is concerned the Yaquina Bay region is es- 

 sentially the same as the Coos Bay region. The codling moth has as yet 

 caused no serious injury there; and the impression is quite generally held 

 that conditions are such that it 'will not thrive. That it is present, how- 

 ever, is shown by the presence of wormy apples in the horticultural ex- 

 hibit at the county fair held at Toledo in the fall of 1901. There as else- 

 where in the state, where the pest has not as yet gained a firm foothold, 

 it would seem far better for the fruit growers themselves to establish a 

 strict orchard inspection and fruit quarantine in the attempt to check its 

 spread rather than to rely on the vain hope that ocean breezes will com- 

 pass its destruction. Other localities have been buoyed up with the same 

 hope only to have it shattered with the passing of the years. In the 

 Oregon Agriculturist and Rural Northwest, January 15, 1899, occurs the fol- 

 lowing quotation from the Pajoronian of Watsonville, California: "The 

 codling moth has not been kept out, for any great length of time, of any 

 of the districts where apples are produced for general sale. Every new 

 apple district is 'without the codling moth territory.' We have talked 

 that way about Pajaro valley; but the codling moth has not kept away
