I have found a kitchen account book is a very
useful record. I have a small vestpocket note book hanging by a string and
pencil near my kitchen range. A page or two is devoted to each month's
use. The month and year are entered at the top of page. When groceries are
purchased, the date, article and price are noted, and summed up at the end
of each month. It makes a handy, permanent record, showing how long
supplies last, the expense of one month compared with another, and the
monthly average of each year.
