“The handling of our forests as a continuous, renewable resource means permanent employment and stability to our country life. The forests are also needed for mitigating extreme climatic fluctuations, holding the soil on the slopes, retaining the moisture in the ground, and controlling the equable flow of water in our streams.” MeanCountryWaterNeededResourcesFlowExtremesForestsOur CountryEmploymentPermanentStreamsSoilStabilitySlopesCountry LifeFluctuationRetainingMoistureRenewable Resources Book:Public Papers of the Presidents of the United States: F.D.

“The winter oak... is very useful in buildings but when in a moist place it takes in water to its centre... and so it rots. The Turkey oak and the beech both... take in moisture to their centre and soon decay. White and black poplar, as well as willow, linden, and the agnus castus... are of great service from their stiffness... they are a convenient material to use in carving.” WellsUseBlackWaterWhiteBuildingMaterialsWinterDecayCentreTurkeysConvenientOaksCarvingGreat ServiceMoistureStiffness Author:Marcus Vitruvius Pollio
“The larch... is not only preserved from decay and the worm by the great bitterness of its sap, but also it cannot be kindled with fire nor ignite of itself, unless like stone in a limekiln it is burned with other wood... This is because there is a very small proportion of the elements of fire and air in its composition, which is a dense and solid mass of moisture and the earthy, so that it has no open pores through which fire can find its way... Further, its weight will not let it float in water.” WayWaterFireAirElementsMassStonesWeightWoodsProportionBitternessDecayBurnedCompositionWormsFloatsDenseSapIgniteMoisture Author:Marcus Vitruvius Pollio
“There's a lot of research that suggests that organic yields are close or superior to conventional yields depending on factors like climate. In a drought year an organic field of corn will yield more - considerably more - than a conventional field; organic fields hold moisture better so they don't need as much water. It simply isn't true that organic yields are lower than conventional yields.” NeedsYearsWaterFieldsResearchClimateSuperiorsFactorsYieldConventionalCornDroughtMoisture Author:Michael Pollan
