lumpless perfection and serve up with brown sugar and fresh whole milk delivered each morning by the milkman. Grandma was good at keeping the house in order, like making sure our sheets and pillowcases stayed fresh, and there was always something baking in the oven, like bread, pie, or butter tarts.

Reinstall the cables when you are done cleaning them, and apply a small quantity of grease to the top of each battery terminal to help prevent corrosion. 274 Maintenance and Care Battery replacement If your original…

In the first centuries of Islam, the gardens pro­ vided sensual pleasures-the scent of orange blossoms; the water burbling and cooling the baking air; shade-to rulers. Once the gardens became resting places for some of those rulers, their tombs began to transform the verdant settings into earthly representations of the paradise of the Quran-its "gardens beneath which rivers…
