Huck found a spring of clear cold water close by , and the boys made cups of broad oak or hickory leaves , and felt that water , sweetened with such a wildwood charm as that , would be a good enough substitute for coffee 哈克在附近发现了一眼清泉，孩子们就用阔大的橡树叶和胡桃树叶做成杯子，他们觉得这泉水有股子森林的清香，完全可以取代咖啡。

At the same time , the quality of different - state water was studied . the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth , specifically 0 . 74 > 0 . 94 andl . 34g / cm3 , the saturated , canaliculus and field moisture contents decrease gradually in layer a , b and c , accordingly the soil total foveola decreases gradually , and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space , which are respectively 0 . 92 and 0 . 99g / cm3 , and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed 结果表明：冷杉原始森林土壤容重随土层深度的增加而增大，分别为0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，饱和持水量、毛管持水量、田间持水量a层、 b层、 c层逐渐减小，十壤总孔隙度也逐渐减小，土壤的持水能力随深度的增加逐渐减弱；林外空地a层、 b层十壤容重相差不人，分别为0 . 92和0 . 99g cm ~ 3 ，其它规律与林内人体相同：皆伐迹地的低洼地段容易发生逆行演替，形成高原沼泽地。

For the soil infiltration , generally , the order of the original and stable infiltration speed from big to small is the inner , the outer space and the paludal trace , as well as layer a b . in the view of the rainfall balance of the wildwood , the canopy interception is averagely 61 . 10 % of the rainfall , the trunk runoff 0 . 80 % , the inner 38 . 10 % , the surface and the litter evapotranspiration 18 . 00 % , the surface runoff does n ' t appear in the forest , and the interflow is also very small , which is 0 . 30 % of the total rainfall ; the conflux is 21 . 10 % 原始森林的水量平衡中，林冠截留量平均占降雨的58 . 27 ，树干径流量占降雨的0 . 80 ，林内降雨占降雨的40 . 93 ，地表蒸发及地被物蒸散量占总降雨的20 . 13 ，林内很少发生地表径流，壤中流量也极少，只占总降雨的0 . 07 ；汇流量占总降雨的21 . 43 。
