Sixty members and guests registered. On Mondayregistration was conducted in the Strathcona Hotel, where a majority of those participating made their headquarters. The Meetings, held in the Customs Building, were opened with welcomes from Richard Parmeter, Conference Chairman and R. E. Foster, Officer in Charge of Forest Pathology Investigations at the Victoria Laboratory. Particpants in the confere~~ -were· .cordially invited to visit the laboratories and offices of the Forest Pathologists stationed in the Federal Bulding at Victoria. A most interesting array of displays and demonstrations were competently explained by our · hosts. Indeed, most visitors became so engrossed in "talking shop II in the first laboratory they entered that the evening proved too short to canvass everything. The field trip included visits to the B. c. Forest Service Nursery at Duncan (damping off of coniferous seedlings, soil sterilization procedures, etc.) and the Cowichan Lake Forest Experiment Station. The British Columbia Forest Service was our host organization for the day and made arrangements for lunch and coffee breaks. Sev- enty-eight members, guests and wives attended the banquet on Octo- ber 17th, held at the Royal Colwood Golf Club. Phil Thomas, ;Last year's winner of the Wifdwc award entertained the group with an expurgated version of the epic: 11The Story of Rosellini:a ond Bo- letus 11 (The complete, E_expurgated version has been included in these proceedings.) With obvious reluctance, Phil relinquished the trophy to his successor, Toby Childs. For the first time an award was made to an associate "member" on the distaff side, Mrs. James w. Kimmey. Hr. Thomas Wright, Dean of the School of For- estry at the University of British Columbia presented a thought- provold.ng discussion of the Future of Forestry in the Province of British Columbia. The tenth w. I. F. D. w. c. was adjourned the afternoon of Octo- ber 19, 1962. the last item of business was the acceptance of the by no means "off the cuff" invitation of Lowell J. Farmer "' for next year's conference to assemble at Jackson Hole, Wyoming. ,,. Executive Committee Program Committee .. J. R. Parmeter, Chairman K. R. Shea, Chairman c. G.

R, Panneter ., This is the decennial meeting of the Western International Forest Disease Work Conference. Since its origin, ten years ago, ·the Conference has become one of the most valuable and looked-forward-to meetings of the year. I think you'll all agree that the success of W.I.F .D.W.c. is due in no small part to the infonnal atmoshere . surrounding our discussions and to the energetic participation of all members. For our tenth meeting, your program committee, ·Keith Shea, Jack Roff, and Bob McMinnhas provided several interesting topics for consideration, Your local arrangements comittee, Bob McMinnand the entire Victoria staff, has provided the necessary surroundings and accomodations. I know that you will provide the discussion. · There are any number of comments a chairman might make to open the meeting, but it is customary for some person of high position in the meeting locale to extend a welcome and to extoll the virtues of his particular environment, So with- out further ado, l'd like to introduce Ray Foster. ADDRESSOF WELCOME R• . E. Foster Mr. Chairman, Members, and Guests of the Tenth Western Inter- national Forest Disease Work Conference: I have the pleasure of welcoming you to Canada1s most beauti- ful city and to the major center of research in forest path~ ology in North .America. Admittedly, these observations may con~a.in some element of biased personal opinion, but I am confident that any doubts you may have in either regard will be dispelled long before you leave, ¥ ·This is our 10th anniversary, and I would be remiss in my , capacity as Conference Historian (an honour bestowed upon me in my absence from the last annual meeting) if I did not offer at least one commentbearing on this event. I am very pleased to note the presence of Senor Riquelme Inda. Although Sr. Riquelme has been in correspondence with us for several years and has forwarded papers .for our Proceedings, this is the first time that we have had the privilege of wel- I' -2- I ., f ,r ,. t coming him to Canada and it is evident that our meeting will take on further international flavour, and benefit from this wider association. This is not the first time we have met in Victoria - our very ___first Conference was held here in '.L953. The primary ob- jective then, and now, was to bring together those engaged in surveys and research in forest pathology in western North America to promote the exchange of infonnation on forest dis- eases of mutual interest and concern. A review of the subject matter contained in the Proceedings of our nine previous Conferences verifies that this primary objective has remained in sharp focus. In my opinion it is this sense of purpose which has · enabled us to retain our status as a Work Conference. Admittedly, · .we have entertained other matters over the years, but these excursions have broadened our understanding of regional problems and have not impeded our progress or diverted us from our primary goal. If we can retain tlµ.s sense of direction I am confident that our next decade will be marked with progress equal to that achieved to date. We have come a long way during the past 10 years but we have a great deal left . to do, and it is evident that there will be need for meetings of this nature well into the future. We reqognize problems today which we were completely unaware of in 1953; and in respect to problems included in our first agenda that are still with us, new concepts and techniques have developed which warrant our consideration. In this con- nection it may be of interest to note that a number of sug- gestions for future programs were made last year, a.nd printed in our Ninth Proceedings. I have examined this list of some 23 suggestions, but have been unable to find any that have baen _ incorporated in our present agenda. Despite ,this, I am confident that there is much on the program to hold your in- terest and stimulate your connnent. I am very pleased to welcome you to the City of Victoria during its Centennial year, and on behalf of the Victoria Laboratory to the Work Conference during its tenth .birthday. I ext'end to you the facilities of our laboratory during your visit and I wish you success in your deliberations. Thank you. ,, 3- .I t GREETIM}S FROM MEXICO Julio Inda Riquelme Ladies .and Gentlemen; First of all I want to thank the Board of Directors of this Conference for the opportunity they have given me to convey · · the greetings •of' the -Secretary of Agriculture of the Republic of .Mexico, Mr. Julian Rodriguez Adame, and also of Dr. Enrique Beltran, Sub-Secretary of Forestry Resources, who have given me their representation to attend this meeting and to wish · you a most successful Conference. At the same time, allow me, in behalf of the Sociedad Foresta1 · Mexicana and as Life President, to give you a most cordial salu- tation _and very best wishes £or the success of the working ses- . sions, which without any doubt will be a tremendous value. · Ourgovernment and the Society I represent ·wish to continue clooe relationships and the exchange of works re9~ar.Qh on plagues and diseases of trees with you. ·such cooperation un- doubtedly will benefit all three countries. We hope that in the near future Mexico can be honored by this conference holding its meetings in one of our many beautiful states - giving us the opportunity to express our sincere and real friendship.
