1 c. wild rice

6 tbsp. chopped onion

Butter

2 lb. ground chuck or round

1 lb. mushrooms

1 bay leaf

3/4c. chopped celery

2 c. cream of chicken soup

1 1/4 tsp. celery or garlic salt 1/2 c. slivered almonds

Wash, and soak wild rice for 15 minutes in 3 cups boiling water; drain. Saute onion in butter; add meat and brown. Simmer mushrooms in 1 cup water with bay leaf until done. Combine all ingredients except almonds. Put in casserole; top with almonds. Refrigerate overnight. Bake at 350 degrees for 1 hour and 30 minutes. Yield: 10 servings.

Abrasive materials may be either natural or synthetic. Traditional abrasives are all natural, and the synthetic ones are a fairly recent innovation.

The oldest abrasive of all is sand, which was used for polishing stone weapons as early as 25,000 BC. Other abrasive materials in use from early times include garnet (a hard, glasslike gemstone), emery, pumice, and silica (silicon dioxide) which occurs in various forms as quartz, flint and agate. In the Middle Ages, grinding wheels of quartz and flint fragments naturally bonded together in rock were used. Gemstones were lapped or polished by the use of emery or sandstone powder rubbed on with metal plates.

After the food leaves the stomach, it is acted on by several digestive enzymes. Some of these are secreted by glands located, like the stomach glands, in the wall of the intestine. But the most powerful digestive juices of all are those secreted by the pancreas and poured into the intestine in its upper part. One of the pancreatic enzymes, trypsin, is a rapid and powerful split-ter of the protein foods. Another, lipase, splits fats into simpler absorbable compounds. The third, amylase, resembles the salivary secretion, ptyalin, in that it breaks down complex starches and sugars into simpler chemical forms. The pancreatic secretion mixes with the food, as has been said, at the upper part of the small intestine.

The abrading effect is produced almost entirely by the simple physical process of the harder substance shearing or fracturing small chips off the work-piece to smooth it.

Abrasives are used in three main ways. One is to use the abrasive material directly on a substance: sharpening a knife on a grinding wheel is an example of this. Another is to coat another substance, such as a piece of paper, cloth or rubber on a metal disc, with granules of abrasive material, and use this as a tool; sandpaper is the commonest application of this technique. The third method is sandblasting or gritblasting, where a powerful stream of air containing abrasive particles is directed at an object to abrade its surface.

The flash of the Hiroshima bomb was so intense that it discolored concrete and sealed the surface of granite, leaving in many places prints of the shadows cast by the light of the explosion. By triangulating these shadows with the objects that had cast them, Japanese scientists were able to pinpoint the exact center of the blast. Some of the shadows were of people.

Today’s nuclear warheads are smaller and more powerful than ever before, in order to maximize the efficiency of the delivery system. At the outset of the Manhattan Project, Albert Einstein was one of the scientists who forecast that an A-Bomb would have to be so large and heavy that it would need a ship to deliver it to its target.

The stomach empties itself in about four hours. The food, in various states of digestion, is then carried forward by the intestinal peristalsis, which is much like the constrictive movement of the stomach. It is carried forward at a rate allowing time for the intermixture of intestinal, pancreatic, and liver juices, for the conversion of food into assimilable form, and for absorption, through the intestinal walls, into the blood. Finally, through the ileo-ca2cal valve, it reaches the large intestine, where absorption, except for water, largely ceases and the waste products are agglutinated with the mucous, bacteria, and epithelial debris from the entire intestinal tract in the form of faeces, a stool or mould of which is evacuated from the body by the act of defecation once, according to the immutable standard of modern civilization, in every twenty-four hours.
