volume XXXV. OF THE CANADIAN FIELD-NATURALIST 

 Owing to a strike on the part of the printers and to other causes beyond the control of its Editor, 

 Volume XXXV. of The Canadian Field-Naturalist has not yet been completed. Numbers 7 to 9, inclu- 

 sive, will appear in one issue, which is now in press. A change in the place of publication from Gardenvale, 

 Quebec, to Ottawa, Ontario, makes it possible for this first number of Volume XXXVI. to be published 

 without waiting for the close of the pre-\dous volume, although the usual cover-design must be dispensed 

 with until Volume XXXV. is completed. Editor.
