team. A means taken to prevent the spread of the Ocneria was the 

 employment of officers with authority to stop and examine every team, 

 carriage, horse car, or person passing outside the limits of Maiden and 

 Medford and to examine the same. Though the utility of this work 

 was doubted from the first it was continued until most of the larvre 

 had transformed into pupse. In the fall months the Commission also 

 did some work destroying the egg masses. 



On February 25, 1891, Governor Russell, acting under authority of 

 Section 5, Chapter 95, acts of 1890, sent a message to the Legislature 

 and to the Executive Council removing the Commissioners for cause and 

 placing the work in charge of Messrs. W. E. Sessions, ]S". S. Shaler, 

 and F. H. Appleton. All the new appointees are connected with the 

 State Board of Agriculture and serve gratuitously. See Insect Life,

 the Committee placed the field work in charge of Mr. E. H. Forbush, 

 to whose tireless energy most of the good results are due. 



Starting with the information as to the limits of the infested region 

 given by the Commission of 1890 it was soon discovered that the Ocneria 

 was abundant in many places in addition to those reported. It can 

 now be stated to occur in Marblehead, Salem, Swampscott, Lynn, 

 Lynnfield, Reading, Wakefield, Saugus, Revere, Chelsea, Charles town, 

 Cambridge, Somerville, Watertown, Waltham, Belmont, Arlington- 

 Lexington, Burlington, Woburn, Winchester, Stoneham, Melrose, Mai, 

 den, Everett, and Medford. There is a great difference in the abun- 

 dance of the Ocneria in the various localities, and the bulk of the dam- 

 age has been confined to Everett, Maiden, Medford, and Arlington.
