SUMMARY OF DISTRIBUTION AInD PRESENT CONDITION. 25 



MARYLAND. 



Maryland early became one of the eastern States worst infested by 

 the San Jose scale, and one that suffered most, perhaps, from this 

 pest. It also received the most energetic earh^ work in efforts at 

 extermination and control. The present situation, as indicated by 

 Mr. T. B. S3anons, State entomologist, shows the San Jose scale to be 

 generally distributed over the entire State, with the exception of the 

 two extreme western counties, Garrett and Allegany, the former hav- 

 ing the San flose scale at 2 points and the latter at 15. By the method 

 of employing State inspectors in the various counties, 1,500,000 trees 

 of various kinds have been inspected each year for the past four ^^ears, 

 and from the records thus gained 18 per cent of the fruit trees in- 

 spected are infested, and 65 per cent of the orchards, and this estimate 

 is believed to be moderate. 



MASSACHUSETTS. 



The presence of the San Jose scale was determined in Massachusetts 

 as early as April 25, 1895, as recorded in Bulletin 3. Additional rec- 

 ords are given in Bulletin 12. Prof. H. T. Fernald, summing up the 

 present situation, says that he was forced to give up the effort of 

 keeping a complete list of localities known to be infested in 1900, 

 finding that the scale was practically everywhere in Massachusetts 

 east of the Connecticut River. At the present time it may be found 

 in almost every town to the western boundary of the Connecticut 

 Valley, say 15 miles west of the river on the average. In Berkshire 

 County, which lies west of this, he has no records, but he would not 

 be surprised to find it somewhere in that region, particularly along 

 the Housatonic Valley. As to percentage of infestation, he says that 

 about one-third of the orchards are infested to a greater or less degree, 

 and the infested orchards are particularly the more recently planted 

 ones. In the older orchards infested replants may occasionally be 

 found. Many of the cases of infestation, however, are of ornamental 

 trees and shrubs in house lots. He states that from such places as 

 the Arnold Arboretum and the Metropolitan Pai'k system around 

 Boston, which have had the scale for nearly fifteen years, it has 

 spread in all directions, and that in Massachusetts it is less an orchard 

 problem than one of ornamental plants. 



MICHIGAN. 



Michigan was not known to be infested at the time of the publica- 

 tion of Bulletin 3, but Professor Barrows, in August, 1897, reported 

 14 localities in 10 counties, the evidence showing that the scale had 

 been present in the State since 1890. The present situation is indi- 

 cated on a map prepared b}^ the entomologist of the State experiment
