Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 edition. Excerpt: ...and taste their saps. Tap one tree on north and south sides and compare sap-flow. Tap other trees with one hole Only. 2. Observing sap-flow from natural wounds, from tap pings of birds, from gnawings of animals and from broken green boughs and twigs. 3. Observing the animals that take advantage of the sapflow. Birds and animals may be seen feeding at their own tappings. If there be snow on the ground, the tracks of animals about the places where sap flows down the trunks to the ground will tell of nocturnal visitors that have a "sweet toot." Insects will be found swarming in the sunshine to every flowing wound: bees and flies and beetles of many Sorts. These may be picked up in a cyanide bottle. The gathering of the sap from the pails during the entire period of flow, and the evaporation of it, are tasks too prolonged for a class exercise, and should be arranged for by the instructor. The making of syrup or sugar from the sap is accomplished by boiling to evaporate the excess water and skimming to remove floating impurities, and may be done _ indoors or out, and in amounts large or small by anyone. For syrup, the sap should boil until a thermometer immersed in it (not touching the sides or bottom) registers 219 degrees Farenheit; for sugar, until it registers 238 to 240 degrees. After reaching this temperature, the fluid sugar should be removed from the fire, stirred for a time to secure uniformity of granulation, and then poured into small moulds of any sort, paper or tin, to harden. No suggestions as to the disposition of the product will be needed. The record of this study may consist of: 1. A diagram of the apparatus in place in a tree that is properly tapped, with explanations. 2. Notes on the sap of the various trees...show more
