What reading level is Teachers Manual for the Andrews Lunar Tellurian Manufactured By Cf Weber Co book?
To quickly assess the difficulty of the text, read a short excerpt:
It is not necessary that the moon be exactly at her node to strike the earth's shadow, for, if within 10 ^degrees either before or after the node, she will pass into the earth's shadow and be wholly or partially eclipsed, according to her nearness to or distance from the node when she " fulls. " This distance, 10^ degrees either way from the node, is called the " lunar ecliptic limits. " Thus we see, that at either node there is a lunar eclipse limit of 21 degrees ; includ ing both nodes, 42 de...grees, within which limits all lunar eclipses must occur.
Move the arm IX of the globe forward, until the moon ball is brought to " full, " as shown in cut No. 2 ; loosen ^the screw holding plate E, and turn the plate until the gear-wheel that drives the moon ball rests upon the lower part of the plate$ as shown in cut ; tighten the LUNAR TELLURIAN MANUAL. 63 screw, ask the pupils to observe, that now the full moon is below the ecliptic (the line J, as marked upon the globe), and that the shadow of the earth will pass above the moon, and no eclipse will occur.
