EASY-DOES-IT SPAGHETTI

I have never made this recipe.  It is from the little recipe/instruction book that came with my first crockpot back in the early 1970s.

1 lb ground beef
1 tbsp instant minced onion
1 1/2 tsp salt
1/2 tsp garlic powder
1/2 tsp dry mustard
1/4 tsp each: mace, allspice, and pepper
4 ounces dry spaghetti (1 1/2 cups) broken in 4 - 5-inch pieces
8-ounce can tomato sauce
4-ounce can mushrooms
3 cups tomato juice

Brown ground beef well in skillet and place in CROCK-POT.  Add all remaining ingredients except dry spaghetti; stir well.  Cover and cook on low for 6 to 8 hours. (High: 3 1/2 hours) Turn to high last hour and stir in dry spaghetti.
