SUMMARY OF DISTRIBUTION AND 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 early work in efforts at 
extermination and control. The present situation, as indicated by 
Mr. T. B. Symons, 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 Jose scale at 2 points and the latter at 15. By the method 
of emplo} T ing State inspectors in the various counties, 1,500,000 trees 
of various kinds have been inspected each year for the past four years, 
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 eveiy 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 saj^s 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 Park 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 
11 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 hj the entomologist of the State experiment
