State Board of Health Finds Malaria Worse in Drouth and Burned Regions of Georgia - Woods Fires Favor Breeding of Malarial Mosquitoes. 
The State Board of Health of Georgia reports an increase in the number of malaria cases in sections of Georgia following the drouth and forest fires of 1931 and 1932. It is believed by the board of health that forest fires were an important factor in this increase by creating conditions favoring the breeding of the malarial mosquitoes. 
It is pointed out by the board that the mosquitoes that transmit malaria breed in water that is neutral or alkaline, that thf'y avoid water that is acid. Except in the limestone regions of south Georgia, swamp waters, in the absence of forest fires, are too acid to make breeding places for the malarial mosquito, though they breed other mosquitos. As an example, Okefenokee swamp was carefully searched by federal men for larva of the malarial mosquito without' success. The waters of the swamp apparently contained too much organic acids to suit that breed of mosquitos. 
It has also been found that the greatest number of malarial mosquitos and the greatest number of cases of malaria coincide with the limestone belts of the state, showing that lime in solution in the water makes a condition favorable for breeding the malarial mosquito. 
Why forest fires make swamps less acid and more favorable as breeding places of the malarial mosquito, is explained by the fact that the ash left by fires contains lime, potash and other minerals which enter readily into solution of rain water. This neutral or slightly alkaline water has filled up dry or burned swamps and created a condition favorable for breeding of malaria mosquitos. The slow filling of dry swamps after a long drouth has probably favored the malarial mosquito more than in the absence of severe drouths. But the evidence seems to point to ash of burned W6ods leaching into swamps at any time as liable to so modify the chemical condition of the water as t.o favor the breeding of lllalaria mosquitos. 
 
An appeal is made by the State Forest Service to people everywhere not to set fire to their timberland and to use precaution burning fields or brush. A large acreage of young

timber will probably be ruined or greatly set back in growth by fires, unless people can be made to realize that burning timber even in damp weather, can not be done without burning all needles off large saplings and killing outrig,ht the small seedling tree. People are urged by the Forest Service not to burn their land this year, and thus reduce the large economic loss to the State such burning annually causes. 
 
"Marginal land" is a term that has come to mean land not capable of being profitably used for agriculture. Marginal land may be land once used for agriculturai crops but now abandoned and for the present, at least, not needed for producing food. It may also include badly eroded land no longer suited to farm crops; marshes, overflow land, rocky, steep and inaccessible lands, cut-over areas not reforesting, and range lands of low quality. 
No survey has been made to determine 
 
how much marginal land exists in Georgia. 
 
The question might be asked as to whether the drying up of the swamps has not eradicated the natural enemies of the mosquito, notably fish. The answer to this is that in limestone regions, fish and other natural enemies of the mosquitos have never controlled the mosquito. Whatever effect the natural enemies may have the fact is that they are not now in the swamps that were dried up and therefore, can not be 
 
Estimates vary from three to five million acres. Some land that might be termed unprofitable farm land during the country's depression would strictly speaking be "marginal land", but would not be so classed under normal conditions. Nor would any land that is unprofitable because of poor farm practice be rightfully classed as "marginal land".

FORESTRY QUE.STION BOX 
Ia it obligatory in Georgia to sell timber only by the Doyle rule? 
While the Doyle rule is legal in Georgia, the timber owner has the right to contract on any basis he can get the purchaser to agree. F'or instance, the sales of timber from the National Forests of Georgia arg made according to the Scribner rule. 
Are the pines used in France for turpentining the same species as those used in southern states? 
The pine used by France is not the same as those used for turpentining in the southern states but is known as the Maritime or Cluster pine. 
How long does it take for scars made by fire on hardwood trees to heal? 
Investigations made in bottom lan d hardwoods of the Mississippi river by F . H. Kaufert of the Southern Forest Experiment Station r evealed the average fire scars unhealed 15 to 20 years even on young trees. Red gum, white oak and red oak, he found, form wood tissue faster than ash, hackberry and hickory. Fifteen year old scars on red gum, red oak and black oak were approximately 50 per cent healed, whereas scars of the same age on ash, hackberry and hickory were 30 per cent as large as they had been originally. 
How much national forest land was purchased in Georgia in 1932? 
According to the National Forest Commissions report 60,774 acres were purchased in 1932 at an average of $5.08 per acre. An additional 5,853 acres were approved for purchase. These purchases and approvals were for the Georgia section both of the Cherokee and Nantahala National Forests.

IN APPRECIATION OF MR. C. B. HARMAN 
The retirement of C. B . Harman from the Commission of Forestry and Geological Development removes from this department one who has served, long, faithfully and well. He was a pioneer in Georgia forestry activities, helping to create the sentiment that r esulted in the formation of the Georgia Forest Service. 
F'or eight years, or during the entire life of the State Forest Service, he has been a member of the board and commission directing its affairs. No one has been more keenly interested, nor has done more constructive work in directing and in upbuilding forestry in the state. 
Mr. Harman is a lumberman who has looked to the future and given much time a nd thought to growing trees. He is chairman of t he exec utiv e co mmittee of the Georgia Forestry Association and recently has promoted forestry rallies that have proven highly successful. 
Mr. Harman is author of several technical books pertaining to mill work and for several years he was an executive in a southern mill work association. He wil! co ntinue his interest in fore stry, centering his activities in work of the Georgia Forestry Association and will co ntinu e to work with his many friends over the state in forestry promotion.

On January 4th, the Executive Committee of the Georgia Forestry Association held an executive committee meeting and a public meeting in Augusta. The first waE held in the afternoon when the committee discussed the business affairs of the a!.sociation. The public meeting was held in the ballroom of the Richmond Hotel at 8 :00 P. M. and was attended by approximately 40 people from Augusta and the surrounding territory. Mr. M. H. H . Duvall, President of the Augusta Chamber of Commerce presided. Among the notable speakers were Mr. T. G. Woolford, of Atlanta; Miss Emily Woodward, Vienna; Mr. C. B. Harman, Atlanta; Mr. J . M. Mallory, Savannah; Mr. James Fowler, Soperton; Dr. Chas. H. Herty, Savannah; Judge Ogden Persons, Forsyth; Mr. B. M. Lufburrow, State F orester, Atlanta; and Mr. Tom Hamilton, of Augusta. 
Mr. Woolford, president of the Georgia Forestry Association, outlined the plan and program of work of the association for the co ming year. He said that both a timb e r and water power survey for the State were needed. Mr. Lufburrow spoke of the growth and development of the state forestry department within the last few years, and outlined some of its purposes and aims. Dr. Herty spoke briefly of t he development of the paper industry in Georgia. Other members of the committee spoke briefly of the various activities of the association. Many Augustans have expressed their appreciation of the splendid work being done by the Georgia Forestry Association. 
Long Leaf Pines Planted By Boy Scouts

Walnut lumber ranks at the top both in value and popularity. There has always existed a big demand for walnut lumber the world over. For interior finish it has no superior.

TEN-YEAR NAVAL STORES EXPERIMENTS 
Reviewing Technical Bulletin 298 used by Lenthal Wyman of Stark, Fla., United States Forestry Experiment Stations, in the Forest Worker, Dr. Austin Cary of the Federal Forestry Service and well known in the South, says, among other things: 
"In the first place, Mr. Wyman has found that the yield gains fast with the added size in trees worked. He correlates specific yields with specific sizes. Further he infers that vast numbers of trees commercially worked are unprofitable. A tree's environment, too, affects its yield: open standing trees, with generous crowns, yield significantly more than trees of the same diameter that are crowded. Individual variation in yield is another thing that has come out. Of two trees of the same size that look alike and stand in similar relations, one may yield two to four times as much as the other. Microscopic study has not determined any structural ground for such individual differenc,e. That fact, of course, takes the work out of the strictly mathematical or mechanical class, calling for a repitition of tests of large numbers of trees and for the use of averages. 
"Mr. Wyman has carried out elaborate experiments in chipping the weekly wounding of trees of the tree from which the flow of gum results. These experiments are concerned largely with three details, the best width of face; the best depth of chipping, and the best rate of progress up the tree, current yield of gum and the maintenance of the yielding power of the tree both considered. 
"In relation to existing practice in the region, Mr. Wyman's findings are conservative, but in recent years commercial practice has to some extent been going along with him."
