AMERICAN FORESTRY 



been found rather alniiidantly in the northwestern part 

 of the state. 



Two specimens of diseased pine liave been reported 

 from a nursery located at Cuyahoga Falls, Ohio. 



Scouting in Maryland, Virginia, West Virginia, Nortli 

 Carolina. South Carolina and Georgia has thus far re- 

 vealed no blister disease. Planted pines in these states 

 are not abundant, but scouting has revealed a larger 

 number of plantings and a greater abundance of wild 

 currants and gooseberries than was previously suspected. 



The blister disease has been found on imported pine 

 in a nursery at Pontiac, Michigan. These trees came 

 from France in 1910 and all shipments from this nursery 

 are being traced. A force of eight men are engaged in 

 general scouting under the direction of Dr. Pennington, 

 of Syracuse University. 



A few currant and gooseberry infections found close 

 together near St. Croix, Wisconsin, have been reported, 

 but the source of this infection has not yet been discov- 

 ered on pine. A force of 24 men are scouting the state. 



More than a dozen infections have been found in the 

 St. Croix valley, in Minnesota, scattered over a territory 

 approximately 60 miles long and 10 miles wide. Sev- 

 eral native pine trees and many currants and gooseber- 

 ries were found diseased. Infections appear to be spotted 

 over the valley and an attempt is being made to eradi- 

 cate the disease on both pine and currants and goose- 

 berries. Pine stock shipped from nurseries has been 

 traced and several of these shipments were found to be 

 diseased. Twenty-six men are engaged in scouting and 

 eradication. 



One tree on an estate located at Estelline, South 

 Dakota, has been found diseased. The tree came from 

 an infected Minnesota nursery in 1911 and illustrates 

 the danger of spreading the disease through shipments 

 of nursery stock. 



Bli.ster rust scouting is now carried on in Iowa, 

 Illinois, Indiana, Missouri, Kentucky, Tennessee, Ne- 

 braska. Kansas and North Dakota, in co-operation with 

 the various state authorities. Thus far this year no dis- 

 ease has been discovered in any of these states, although 

 numerous plantings of pine have been found and exam- 

 ined. 



Survey work in the Rocky Mountain and Pacific 

 Coast States having native five-leaved pines has thus far 

 revealed no evidence of the presence of the white pine 

 blister disease. The rumor that the blister disease was 

 found in the State of Washington is apparently un- 

 founded. 



A fungus having somewhat similar appearance to 

 the white pine blister disease was found in Kansas In 

 1892 and in Colorado in 1897 and later. Inoculations 

 by members of this office have practically proved that 

 the rust on currants and gooseberries in Colorado if 

 not the white pine blister disease. 



Specific appropriations for the control of the white 

 pine blister disease have been made as follows: 



Massachusetts, $50,000. for 1 year ; New Hamp- 

 shire, $28,000, for 2 years: Vermont, $20,000, for 2 



years: Maine, $10,000, for 2 years; Connecticut, $20,000, 

 for 2 years; Rhode Island, $2,500, for 1 year; New 

 York, $25,000, for 1 year; Pennsylvania, $10,000, for 

 I year; Wisconsin, $15,000, for 2 years; Minnesota. 

 $15,000, for 2 years. 



The Federal Government appropriated $300,000 for 

 the fiscal years 1917 and 1918, $150,000 of which is being 

 expended on a dollar for dollar basis in the various 

 states which have made appropriations for this work. 



The present outlook for controlling the disease seems 

 to center entirely on whether or not wild currants and 

 gooseberries can be completely and economically re- 

 moved and whether owners of cultivated currants and 

 gooseberries prefer to lose their bushes rather than the 

 pine. Professor E. G. Cheyney, Dean of the Minnesota 

 Forest School, is engaged in a study of the eradication 

 problem from every angle. He has suggested that in 

 each demonstration control area data be secured thi-- 

 year for providing accurate information in the future 

 on the efTectiveness of control and the rate of progress 

 of the disease outside of control areas. A rough topo- 

 graphic map will he made showing the distribution of 

 pine by age classes, also showing type of area for cur- 

 rant and gooseberry growth, such as swamp, open 

 meadow, brush land, pine woods, hardwood forests, etc. 

 In the control area the record of these plants by species 

 and amount of infection will be made, for each type, 

 on permanent sample plots 50 feet square. Outside of 

 the area several lines radiating from the control area 

 will be run for some distance to provide check plots for 

 determininsr the rate of advance of the disease.
