Wash and thinly slice the tomatoes and onions. Discard any with blemishes.
Sprinkle over the vegetables, one half cup of canning salt. Let stand overnight in a stainless steel or enamel pan or crock.
Tie the pepper, cloves, allspice and celery seed in a square of cheesecloth; fasten with cotton string. Slice the lemon and chop two peppers very finely.
Drain the tomato and onion well. Add all the seasoning except one of the pepper pods to the vinegar, then add the tomato and onion. Cook for 1/2 hour, stirring gently at intervals to prevent burning.
Remove spice bag to prevent darkening.
Pack in pint jars and garnish with slender strip of red bell pepper and 1 small hot pepper per jar (near the outer edge as decoration). Ladle hot vinegar mixture over jars, leaving 1/4 inch headspace.
Adjust lids. Process for 15 minutes in a boiling water bath canner.
