Instructions: Quantity: An average of 21 pounds is needed per canner load of 7 quarts; an average of 13 pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 15 to 21 quarts-an average of 3 pounds per quart.

Procedure: Wash tomatoes. Dip in boiling water for 30 to 60 seconds or until skins split, then dip in cold water Slip off skins and remove cores.

Leave whole or halve. Add bottled lemon juice or citric acid to the jars

(See acidification instructions). Add 1 teaspoon of salt per quart to the jars, if desired. Fill jars with raw tomatoes, leaving 1/2-inch headspace.

Press tomatoes in the jars until spaces between them fill with juice. Leave 1/2-inch headspace. Adjust lids and process according to the recommendations in Table 1, Table 2, or Table 3, depending on the method of canning used.

NOTE: This
section of the guide appears to contain errors in the information given within Table 1 above. In the USDA book, there are only TWO sizes of jars specified in the table, but there are THREE separate lines of figures in the table, and it is not completely clear which jar size the second and third entries refer to. I have given the second entrys numbers as those to be used for Quart jars, and below I have reprinted the third entry on the table, for an unknown jar size.
