To keep the conveyor chain to the burners almost empty is the aim of the company through more complete use of all possible lumber waste materials such as the veneer scrap for chips for the pulp and paper industry and the ground bark for mulch and a possible great variety of uses. If all possible waste ma terial is used, company officials figure, the company will not only have a more profit able operation but the burners will send up little if any smoke which might be blamed for air pollution. Helicopters May Help With Traffic Problems Corvallis - (UPD - Closed circuit television and helicop ters will be used more in com ing years to help with traf fic problems, it was predicted at the Northwest Highway En gineering conference here.

Hal "" Ami 237 East Main lance SP 2-2456 rant, he suggested. In all sprayers use Vz pound of neutral copper per 100 gallons, he directed. For dust ing, use 25 pounds of 3 per cent copper dust per acre. : Cornice are reasonably cop per tolerant, but some russet ing will result on other varie ties. Spraying or dusting when the trees are wet will further increase this russet ing, Cordy cautioned. Streptomycin may not be used after the fruit is visible, he warned. Seven pounds of Ziram per acre, or IVz pounds per 100 gallons is. good for scab con trol, he suggested. It has also helped in blight control es pecially where applications have been repeated regularly. Some growers may prefer the better fruit finish even though blight control may not be as good, he explained. Spreaders have not been ap proved for use so should not be added to any spray, Cordy pointed out. The 741-foot Kaieteur Falls on the Potaro River in Brit ish Guiana is believed to be the tallest single-drop water fall in the world. Kogap Producing, Selling Material Called Multi-Bark By JOE COWLEY Mail Tribune Staff Writer Development of a bark by product is one way to help eliminate air pollution and get more outof each log, officials more out of each log, officials figure. To that end, the firm south of Medford is producing and selling a bark by-product call ed Multi-Bark. Multi because it has many uses. It can be usea m puce 01 gravel on walkways, parking lots, on playgrounds, around patios, for mulch on lawns, in gar dens and orchards, according to Leonard Howe, Kogap by products department head. As with two or three other lumber companies in the Med- iora area, tnis is a new pro gram for Kogap. , "We realize that with the increasing high costs of stump age and processing that a lumber mill must get every thing it can out of each log to stay in business," remarked S. V. (Duke) McQueen, Ko gap vice president. This year the company start ed experimenting with a hay chopper converted to shred ding the bark. Using bags supplied by an eastern bag company and offering it for free experimental use by nurserymen, farmers and or- chardists Kogap sent up a trial balloon. For awhile the company kept a large pile of the shredded bark near the National Guard armory south of Medford. Soon demand was exceeding supply. Early this month, the com pany riyt a new hammer mill in production which produces 25 units per day, each unit measuring 200 cubic feet, compared to the 5 units pro duced by the Rube Goldberg type of machine. The new hammer mill uses bark from two chain conveyor belts from the barking machine. The hay- chopper could use bark from only one belt. "We are selling just about all the mill can , produce," Howe said. "We are stockpil ing some of it to get ahead of the demand and to allow it to decompose. One truck is haul ing and one is making de liveries. , Being Used at Fair Multi - Bark, resembling ground coffee, can be seen at the Crater Lions Sportsfair at the Jackson county fair grounds today. The ground under the tent is covered with the material. When the Lions are through with it the ground bark will be used- for landscaping around the Jackson county juvenile detention home, also located on the fairgrounds. Although no real orchard test has been made of the ma terial, Bear Creek orchards is working with Kogap to re search its use. County Horti cultural Agent Clifford B. Cordy is also experimenting with it. Harold White, super intendent of the Southern Ore gon Branch Experiment sta tion located on Hanley rd. near Jacksonville, has also taken: some of it. The station's experimental program is all laid out this year, but White hopes to work it in with next Stop Ak Poiyttioira plant growth with bark is to equal or exceed the selling better, especially with azal eas, rhododendrons and camellias. Bark is reported to be much cheaper than peat moss, ac cording to current sales prices. Peat moss costs about 35 cents a cubic foot compared to .045 cents a cubic foot, the forest products research center learned. Market 'Potential It's estimated by the Port land Chamber of Commerce that ground bark would have a tremendous market poten tial about 1,500 to 1,700 units could be sold in the Portland area alone based on current sales of peat moss, However, local lumber firms must consider a number of factors in marketing the pro duct, cost of - polyethylene- lined bags, retail handling, transportation - and distribu tion, bagging labor, grinding ad bagging equipment deprec iation, cost of adding nitrogen, warehousing and storage and promotion. Biggest problem is transpor tation, Pacific Northwest costs are higher than other forest producing areas, forestry ex perts , have pointed out. It's not uncommon for freight cost price by 30 per cent. Also, Pacific Northwest producers bear at least a 50 per cent greater state and local tax burden than a southern com petitor, for instance. Forest product imports from Sweden, Norway, Finland and Japan have a strong influence on the U. S. market. Economists working with the lumber industry point out that each product must be managed as a business Itself if it is to profit and grow and finally survive. Whether this bark by-product business can become a profitable one re mains to be seen. The market potential is there if too many firms don't see it all at once.

Main Ashland NEW INSTALLATION This is the Multi Bark machine installed earlier this month. The machine, mounted high on a platform, grinds the bark from the two conveyors streaming from the barkers. The rotary screens can be seen which sift out the ma terial according to the sizes wanted. A year s program. Various schools in the area are using it on their play grounds. Multi Bark is softer than gravel so prevents skin ned knees and unlike gravel will not be tracked into the classrooms. Recently constructed West minister Presbyterian church is using it to absorb the mud while the grass grows and further landscaping is done around the building. The company has also re ceived two letters from Clare mont, Calif., and one from New York requesting ship ments of Multi Bark for resi dential use. Use of bark as a soil con ditioner is not a new idea. Various institutions and ag encies have studied its use, according to a pamphlet pub lished by the Forest Products Research center at Corvallis. The University of New Hampshire in 1956 concluded that bark "is a good mulch for greenhouse growing of roses better than cow ma nure." It stated that bark sand mix is a good rooting medica for grape cuttings and bark is a better mulch than hay or straw for blaeberries. It recommended addition of nitrogen to avoid nitrogen de ficiency in growing plants. A researcher at me Oregon Agricultural Experiment sta tionj Oregon State college, in 1956 discovered that Douglas fir bark decomposes at a slow er rate than sawdust so re quires less supplemental nit rogen. Bark lasts longer than sawdust as mulch, he pointed out in his research paper. Ivory Pine Lumber com pany at Dinuba, Calif., is mar keting all of its bark for a soil amendment. About 10 per cent of it is marketed with out" composting. The remain ing 90 per cent has about 13 per cent nitrogen (dry basis) added in liquid solution and is left to stand about 6 months in piles 5 feet high, 20 feet wide and about 500 feet long. Dwyer Lumber company, 1 Portland, is marketing a gran ulated bark for horticultural use. Demand increased- to where there was a 6 to 12 week waiting period for de livery. However, installation of a hammer mill increased production from 6 to 8 units to about 30 units each day. Supplemental Nitrogen Researchers from the for est products research center : learned that Portland area I nurserymen preferred non ;. composed bark which could j be bought at a lower price and wanted to add their own plant nutrients. However, most authorities seem to agree some supplemental nitrogen should be added to avoid nit rogen deficiency. The Corvallis study points out that bark is not a fertiliz er but a soil amendment that can be used as a mulch to hold moisture and slow weed growth; or it can be mixed into the soil. , Most Portland nurserymen prefer granulated bark dver saw dust since it requires less nitrogen addition, stays in the soil longer, is less conspicuous due to its dark color, and chute sends Ahe material to a truck waiting underneath.' The company has painted its truck bright yellow with Kogap's name (Keep Oregon Green and Productive) on the sides with the words Multi Bark on the cabs of the trucks used for transporting the material. PART OF CHIPPER Another by-product of the Kogap Lumber Industries is the chip material which comes from the chipper. Shown in the picture is the bin and cylone atop it. The waste veneer moves on conveyor belts, drops into a slot and at right angles into the razor-sharp chipper disc. The disc throws the chip material up the pipe. Forced air blows it into the cyclone, and into the bin where air separates the useable material. A screw conveyor then feeds it onto an apron and onto a screen. It then drops down into the feeder and is blown 1,000 feet through a pipe by air pressure, from where a flexible pipe pours it into the waiting railroad cars. ' . , Poison Oalc?
