RE: Question about pitch of underground drainage pipe. Usually perforated pipes are bedded in gravel. When water accumulates in the gravel it'll bubble up in the perforated pipe and at some point it'll discharge out the end. Perforated pipes do not need to be placed on a design slope like a gravity pipe.
Funeral procession arriving at the church. The coffin is covered with an elaborate red pall. A pall (also called mortcloth) is a cloth that covers a casket or coffin at funerals. The word comes from the Latin pallium (cloak), through Old English. It is also a stiffened square card covered with white linen, usually embroidered with a cross or some other appropriate symbol.
Palla is a traditional ancient Roman mantle worn by women, fastened by brooches. It was similar to the pallium that a man would wear. The shape was rectangular instead of semi-circular as with the traditional toga. The Palla was similar to a shawl that a woman of today would wear. The palla would come in many colors some including blue, green, and yellow. The palla is a single piece of material draped over the shoulders and around the body or over the head as well.
