Cartouche's were primarily used to house the names of Pharaoh's, Royals or Egyptian gods only. Cartouches are usually positioned vertically, however they can still be positioned horizontally if the hieroglyphics are longer and need to be repositioned. Hieroglyphics: (Otherwise known as Ancient Egyptian Language) Ancient Egyptian symbols which represent the letters in a name or word. When using hieroglyphics, you spell the word how it sounds, not how it is spelt.
48 md / 4 men = 12 days. If 3 men are digging 6 trenches in 4 days then that means that they are digging 1.5 trenches per day. This means that each man can dig 0.5 of a trench per day. If you have 4 men digging each day, that means you can complete 2 trenches per day. This means that it will take 12 days to complete 24 trenches, using 4 men.
Check yourself as you go. For instance, if the trench for the French drain is to be 100 feet long and the grade 1%, then by the time your trench is 50 feet long, it should be 6 inches deeper than where you began excavating. You will be digging a horizontal trench across the length of the slope.
