""On The Variations In The Water Content Of Trees"" is a scientific book written by James Barkley Pollock in 1896. The main focus of the book is to study the water content of trees and the factors that affect it. The author discusses the different methods used to measure the water content of trees, including the use of a hygrometer and a psychrometer. He also explores the effects of temperature, humidity, and other environmental factors on the water content of trees. The book is divided into several chapters, each of which covers a different aspect of the subject. The first chapter provides an introduction to the topic and explains the importance of studying the water content of trees. The second chapter focuses on the different methods used to measure the water content of trees. In the third chapter, the author discusses the effects of temperature on the water content of trees. He explains how changes in temperature can affect the rate of transpiration and the water content of the tree. The fourth chapter explores the effects of humidity on the water content of trees. The fifth chapter discusses the relationship between the water content of trees and their growth. The author explains how a lack of water can stunt the growth of trees and how an excess of water can lead to root rot. The sixth chapter explores the effects of different soil types on the water content of trees. Overall, ""On The Variations In The Water Content Of Trees"" is a comprehensive study of the water content of trees and the factors that affect it. The book provides valuable insights into the biology of trees and their relationship with the environment. It is an essential read for anyone interested in botany, forestry, or environmental science.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
