FAO - The Food and Agriculture Organization of the United Nations was founded at Quebec. Canada, in October 1945 when its member nations agreed to work together to secure a lasting peace through freedom from want. The Headquarters office of the Organization was located at Washington D.C., U. S. A., until 1951 when it was moved to Rome, Italy. The membership of FAO now stands at 100 nations with 4 associate members.
Unasylva - Started in 1947 by MARCEL LELOUP. first Director of the Forestry and Forest Products Division (present Director EGON GLESINGER), this quarterly publication is intended to cover a range of interests which is as wide as that of the Division whose work it mirrors. Signed articles express the opinions of the authors and do not necessarily represent the views of the Organization. All material published in Unasylva may be freely reprinted but acknowledgment is requested, together with a copy of the publication which contains the reprint. Editor LESLIE J. VERNELL.
Cover photograph. A cargo of about 70 tons of mixed hardwood logs leaving the Curua logging center in the heats of the Amazon forest en route for the Santarem sawmilling training center, 105 kilometers away. A number of these logs are of species not at present used by the timber tale. At Santarem their sawing, seasoning and durability characteristics will be studied as part of the campaign to extend the range of marketable species. The two centers, together with a program in silvicu1tural research, have been established by FAO in co-operation with the Brazilian Government as part of the effort to develop forest industries in the Amazon region.
