The National Forests of Arizona,

A publication of special interest to the residents and tourists of the Sout6west l-ras just been issuecl by the United .Stafes p^epartment of Agriculture. It is D'epart_ ment Circtrlar 318, The National Forests of Arizona. -

This circular describes in some detail each of the nine national forests in that State which cover an area over 12 million.acres in extent and bear a stand of timber es- timated at L4l billion board feet of saw timber and IIV million cords of wood. More than 42 million board feet of timber was cut from these areas in 1923. The annual receipts to the Government from the hational forests of Arizona are nearly $500,000, one-fourth of which is turned over to the counties of Arizona for schools ancl roads.

Each year these forests are visited by over 400.0@ persons seeking recreation within their pieasant boundaiies. and this is a use which the Forest Service encourages to the fullest extent. They have various other importani uses, among which- may be mentioned the grazing -of over hali a million cattle and sheep and the pro-tectioi of the indispensable watersheds of that secti,on, besides furnishing a home for fish and game.

, Thos.e desiring this circular may obtain it free of charge from the Forest Service, Washington, D. C., as long is the supply lasts.

Huge Timbers Being Cut

Canadian Government Gives Order to Ostrander, Wash., Firm

- Kelso,_'Wash., Nov. S.-One of the biggest nrclers for huge timbers every placed in the Pacific nJrihwest is beins cu.!_ by the Ostrander Railway & Timber Company at iti mill at Ostrander, four miles-north of Kelso. -This order is for between 800,000 and 900,000 feet of mammoth timb.ers, to bujld- gates. for the new Welland canal connecting the Great Lakes with the St. Lawrence rrver.

The order was ieceived from the Canadian government. The timbers are from 33x47 inches to 28x3/ inches and are all 51 feet long. Each stick contains from 5000 to 6500 board feet and five of them compose a loacl for ship- ment to their destination. Eleven of these loads already have been dispatched and about 18 more will be requirei to complete the shipment.

Wood Stave Pipe

For the purpose of conveying water in pipe lines under pressure, consideration is usually given to the merits of cast iron, steel, concrete and wood-stave pipe. Each has its- -particular field, and the problem generaliy resolves. itself into choosing the kind of pipe th;t will serve the purpose most economically. In the case of hydro-electric developm.ents, irrigation, and city water suppty lines, where large-sized pipe-lines, from two to fourteen-feet in diameter, are required, and where access to the iob mav be difficult, wood stave pipe has a decided advaniage foi the reason that the materials can be readily transported to the site in knock-down form and assembl6d in plice. The saving made in transportation cost is quite an ltem in the total cost of the installation.

^ W"o9 stave pipe lines are built of Redwood or Douglas fir lumber and reinforced with steel bands to resist the hydrostatic pressrtre. Redwood lumber is preferable for pipe construction on account of its long life, the lvood containing tannic acid, which is a natu"ral preservative. Redwood pipe lines built twenty-five to thiriy-five vears ago. are in use in various parts of the cpuntry, and are still giving satisfactory service.

Wood pipe is also manufactured as small as two inches in diameter, and the smaller sizes are in general use for irrigation and domestic water systems and in mining; chemical, and industrial plants. The pipe will satisfactorily handle certain acid, brine and chemical solntions, which have a tendency to corrode or destroy other forms of pipe.
