nurseries are of course made for the protection of our nurserymen and 

 our own certificate in order that when some of the same stock is again 

 re-shipped back into the states from whence it came, we may possibly 

 be relieved of the embarrassment of receiving a notice of an infested 

 shipment. 



I do not wish to give the impression by what has been said in the 

 forepart of this paper that Ohio is not guilty of sending out infested 

 or at least scale-marked stock. We know that we are because we have 

 been told so and we like to have this information, when such shipments 

 are made. One state has felt it necessary to send her inspector here 

 to examine shipments of some large dealers from that state who secure 

 and pack their stock here. That state happens to be one of the seven 

 already mentioned and the distribution of San Jose scale is general 

 throughout that state. We know this to be a fact because several 

 of our inspectors have worked there in years gone by. 



Here is what I feel that we should be doing in Ohio. Inspect care- 

 fully our nurseries and their surroundings, thoroughly fumigate their 

 stock before it is disposed of and inspect every shipment of nursery 

 stock entering the state. All of this seems necessary for the protection 

 of our fruit-growing interests which our law was created to serve and 

 for which funds are appropriated. What we are doing is spending 

 the major part of our time in inspecting and re-inspecting our nursery 

 stock in the field and on the packing grounds, inspecting stock which 

 they receive from other states, all in order that the last insignificant 

 little scale may be eliminated and our nurserymen's business be pro- 

 tected from injury by being discriminated against in some other state; 

 giving our greatest efforts so far as Ohio is concerned to a relatively 

 small number of men rather than our large number of commercial 

 orchardists, owners of farm orchards and every citizen of the state who 

 plants a tree or shrub, 



I belive that inspection officials, in those states where San Jose scale 

 is not a well estabhshed pest, are right in using the utmost care in 

 preventing infested shipments from entering their states, but it does 

 seem that a different attitude should prevail in those states where con- 

 ditions are similar to those in Ohio. 



THE STATE HORTICULTURAL INSPECTORS AND THE 

 WHITE PINE BLISTER RUST PROBLEM 



By Perley Spaulding 



The white pine blister rust is a disease of five-leaved pines which 

 was brought into this country from Europe some ten or fifteen years 

 ago in imported lots of white pine seedlings. The parasitic fungus
