| Show AGRI CU formation of swamp swamps john gifford in a book on practical forestry says vast areas of fertile land consist almost exclusively of the tho of the forest vegetable tr iatter in the form of humus result ing ng from the decomposition decompo atlon of the litter en on the forest floor has formed 11 many marty places several feet in thick it ss the acreage of swamp lands have been formed in ants way Is in addition to large patch tl of swamps am pa here and there there e many miles of swamp or river tor for eat along our southern rivers the process of eoll moll formation by the an nual addition of vegetable matter may be seen to good advantage in the dia die mal and swamp of the south by digging through tha vegetable accumulation of tho the dismal samp 84 amp top for several feet one reaches sand containing shells this andl in dl cates that the depression in which the swamp was formed was once an arm of the sea it began no doubt as a salt marsh later a tow few trees thit could endure such conditions found a foothold and now it la Is bovere I 1 with a dense forest growth of many species little by little the forest detritus baa has increased in thickness un til till the swamp has reached an eleva tion higher than the surrounding land in fact elevated swamps are common in many parts of this country A swamp Is usually defined as a tract 0 of f land with or without trees loer loner than the surrounding country and do 0 o saturated with water as to be unfit for culli atlon the term swamp in tho south usually refers to a wood ej el region that Is higher than the sur rounding land and when cleared and drained forms excellent farm land how plants use carbon A bulletin of the virginia station says during the houra hours of sunshine all growing plants which teed feed directly idoa soli soil and air must have their as lating chlorophyll bearing cell cells continually in contact with a chang ing volume of air in order that the carbon which makes up tip ao large a part of their dry weight may be obtained in sufficient quantity from the carbonic acid gas in the atmosphere but the more recent analyses of air show that on the average it contains but one part of carbonic acid by weight in 2 parta parts now how much air roust must a field of clover breath in ord that it may produce two tons ot 0 ha per acre aaret let us see bouss lurault found by analysis that 4 pounds of clover by harvested from an acre of ground contained no lesa less than 1680 pounds of carbon and as this was derived almost wholly from the carbonic add acid in the air it must have decomposed decompose 1 aitio pounds of carbonic acid in ordet to procure it but aa as there Is only one pound of carbonic acid in 2000 of air it follows that pounds of air must have yielded up the whole of its carbonic acid gas in order to supply the needed amount of carbon now one cubic foot toot of air at a pressure of 29 2 inches and at a temperature of 62 degrees F weigh weighs pounds and this being true not less than tha n cubic feet of air must have ban bt m required to meet the demands of this clover field fiell tor for carbonic add acid this amount of air would cover the are to a depth of feet living a uniform normal density drouth resistant red clover very linch la Is said about the failure of red clover but it Is worthy of nota note that some ot of the closer plants always come through gli now it seems reason able it the seed of clover plaits platts which are immune to the freezes of winter and the drong the ot of summer were careful carefully lr selected for vigor and for the characteristics already noted that a clover could be obtained and if the history of the ex pertinent perl ment station work Is a cafe safe cri it can be accomplished at no dl tant date the farm r has depend ed antl lely cly on the seeds men and too little on himself in these particulars particular a the time has come when the closest attention must be given to to the production of seeds for home use it would be clearly more profitable and much cheaper to have reliable maedi whose source and quality are known rather than to vasto hundreds of dollars in the purchase of worthless seede seeds as Is 1 cow done andrew M X soule old sed se d corn la in a letter to the farmers review J S leavenworth county kansas says please eay say tu to those answering my inquiries about planting old

experience la is to get cither either a poor stand an enever stand or no stand at all one cannot aco acob 1 to take chances on the corn crop if the seed proves bad it is the loss of very much more
