spectors,” by Prof. Lochhead and issued by the Ontario Department of 
Agriculture in March of the current year. 
While these field operations against the foe have been in progress, 
measures of a different character have been carried out for the prevention 
of fresh invasions. The Ontario Legislature in April, 1899, adopted an 
Act to “further improve the San José Scale Act,” in which it is pro- 
vided that no plants shall be removed from any nursery or offered for 
sale without their being first fumigated by hydrocyanic acid gas, and 
that if the inspector finds the scale in a nursery no plants shall be re- 
moved from it until the Minister of Agriculture on the report of the 
inspector shall give notice in writing that “it is safe in the public in- 
terest to permit the said nursery stock to be removed after fumigation.” 
Immediately after the Act had been assented to, regulations were issued 
by Order-in-Council (April 7th, 1899) regarding the manner in which 
fumigation should be carried out and the precautions that were to be 
taken by those engaged in the operation. The management of the work 
of fumigation and the inspection of nurseries was placed in the hands 
of Professor Lochhead, and thoroughly well he appears to have per- 
formed these important duties. The results thus far have been decidedly 
satisfactory and may justly be regarded as another success scored by the 
science of economic entomology. 
In the Dominion Legislature, as already mentioned, an Act was 
passed in 1898, prohibiting the importation of nursery stock from the 
United States and some other countries. After a year’s experience it 
was found that the severity of this measure might safely be modified, and 
accordingly the Dominion Minister of Agriculture introduced an amend- 
ment to the Act by which the Governor-General-in-Council is empowered 
to select certain ports of entry at which the prohibited nursery stock 
might be imported. An Order-in-Council was issued on the 7th of April 
last naming St. John, N.B., St. Johns, P.Q., Niagara Falls and Windsor, 
Ont., and Winnipeg, Man., as places at which nursery stock might be 
admitted up to the first day of May, on condition that every plant should 
be thoroughly fumigated with hydrocyanic acid gas by a competent 
Government official before being allowed to go further. This conces- 
sion was much appreciated by those concerned, the only complaint being 
that the notice of the amendment was too short in many cases to permit 
advantage to be taken of it. However, it is understood that similar open 
periods will be permitted in the autumn and next spring. 
It is gratifying to know that in all the operations and legislation 
regarding this pernicious insect, our esteemed colleague, Dr. James 
Fietcher, the Dominion Entomologist, has been constantly consulted by
