One day, when the three friends and their dog were very hungry, George said, “I’ll make an Irish Stew... dinner. I'll use some vegetables, the cold beef and some other tilings left over
... our breakfast.” It seemed ... them a wonderful idea. Geoige made a fire, took a pot and poured some riverwater... it. Then he put a dozen ... potatoes, a cabbage and about half a peck...
peas... the pot. Harris added all the left-overs...the stew; then he found half a tin ... salmon** and a couple ... eggs, and put them ..., too. There were some other ingredients that they put
... the pot. And ... last the dog appeared... a dead water rat...
his mouth which was his contribution ... the dinner. The three friends had a discussion whether or not to put the rat ... the stew. Harris said that it would be all right mixed ... the other things, but George said, “I’ve never heard ... water rats... Irish Stew. So, to be on the safe side***, let’s not try experiments.” “If you never try a new thing, how can you tell what it’s like!
Think ... the man who first tried German sausage!” That Irish Stew was really wonderful. There was something fresh ... the meal, it had a new flavour,... a taste like nothing else ... earth.-
