The Scandinavian countries are much admired all over the world for their enlightened social policies. Sweden has evolved an excellent system for protecting the individual citizen from highhanded or incompetent public officers. The system has worked so well, that it has been adopted in other countries too. The Swedes were the first to recognize that public officials like civil servants, police officers, health inspectors or tax-collectors can make mistakes or act over-zealously in the belief that they are serving the public. As long ago as 1809, the Swedish Parliament introduced a scheme to safeguard the interest of the individual. A parliamentary committee representing all political parties appoints a person who is suitably qualified to investigate private grievances against the State. The official title of the person is 'Justiteombudsman', but the Swedes commonly refer to him as the 'J.O.' or 'Ombudsman'. The Ombudsman is not subject to political pressure. He investigates complaints large and small that come to him from all levels of society. As complaints must be made in writing, the Ombudsman receives an average of 1,200 letters a year. He has eight lawyer assistants to help him and he examines every single letter in

L1 Finding fossil man We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas----legends handed down from one generation of storytellers to another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did.

The sagas of these people explain that some of them came from Indonesia about 2,000 years ago. But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first'modern men' came from. Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. Stone does not decay, and so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace.

These lege nds are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did.

Lesson2 Spare that spider Why, you may won der, should spiders be our friends ? Because they destroy so many in sects, and in sects in elude some of the greatest en emies of the huma n race. In sects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat in sects but all of them put together kill only a fraction of the nu mber destroyed by spiders. Moreover, un like some of the other in sect eaters, spiders n ever do the least harm to us or our belongings. Spiders are not in sects, as many people think, nor even n early related to them. One can tell the differe nee almost at a glance for a spider always has eight legs and an in sect n ever more than six. How many spiders are engaged in this work on our behalf ? One authority on spiders made a census of the spiders in a grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre, that is something like 6,000,000 spiders of different kinds on a football pitch. Spiders are busy for at least half the year in killi ng in sects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the in sects destroyed by spiders in Britai n in one year would be greater tha n the total weight of all the human beings in the country. Lesson3 Matterhorn man Modern alpinists try to climb mountains by a route which will give them good sport, and the more difficult it is, the more highly it is regarded. In the pioneering days, however, this was not the case at all.
