Babies this age can focus on shapes that are close by, but see distant objects as blurry because they are nearsighted. As babies grow, eyesight improves. By the end of 3 months, they can follow a moving object, are more interested in shapes and patterns, and can spot familiar faces, even at a distance. Human faces are one of their favorite things to look at, especially their own or a parent's face.
Watch out for cracks, cankers, and holes. Cankers are lesions on the branches and trunk of the tree, often circular or oval, with a sunken center and raised edges. Deep splits through the bark are also signs of possible tree failure. Be on the lookout for sap seepage, whether from a wound or other area of the tree. Sap seepage can be an indication of a bacterial infection within the tree, or damage being done to the tree by insects or birds.
A caustic, toxic sap, called urushiol, is tapped from the trunk of the Chinese lacquer tree to produce lacquer. This is done by cutting 5 to 10 horizontal lines on the trunk of a 10-year-old tree, and then collecting the greyish yellow sap that exudes.The sap is then filtered, heat-treated, or coloured before applying onto a base material that is to be lacquered.ther common names include Japanese lacquer tree, Japanese Sumac, and varnish tree. The trees are cultivated and tapped for their toxic sap, which is used as a highly durable lacquer to make Chinese, Japanese, and Korean lacquerware.
