"It's 8:15 on a Sunday morning,"said the officer,"and this sort of thing seems an unlikely adventure at such a time.Would you mind explaining?" The man was obviously scared but tried to keep calm.He said,"I know what you are thinking,officer,but it isn't true.This is a funny mistake." "It's part of my job to take an interest in unusual events.I think you've just left this house in a manner other than the customary one.That may be quite innocent,but I'd like to make sure."Tidwell took out his notebook and a pen."Name,address and occupation and then,please,tell me your story..." "Charlie Crane,lorry driver,from Nottingham,51 Breton Street.My story..." "Yes.What were you doing like a fly on that wall,Mr.Crane?" "Well,I had a breakdown yesterday and had to stay the night here.Bed and breakfast.Theland-lady's name is Mrs.Fern.She gave me breakfast at seven,and I was out of here in the right way and down at the lorry by half past seven.Only when I felt around for a cigarette did I realize I'd left$80in my envelope under the pillow here at number 29.I always put it under my pillow at night.It's a habit I've got into.I even do it at home..." "I see.Why didn't you miss it when you went to pay Mrs...What's her name?" "I'd paid her last night.You've got to pay when you take the room,see?So I came rushing back,but it's Sunday,and she'd gone back to bed,and could I wake her?I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom window still open.Up I went,then,up this pipe.It's a trick I learned in the army.She didn't make the bed,and money was still there.You know the rest,I hope you believe it because..." "Mr.Crane,whatever are you doing here?I thought you'd gone an hour ago."It was Mrs.Fern,speaking from the kitchen at the corner of the house.

Article: Seventeenth-century houses in colonial North American were simple structures that were primarily functional, carrying over traditional designs that went back to the Middle Ages. During the first half of the eighteen century, however, houses began to show a new elegance. As wealth increased, more and more colonist built fine houses. Since architecture was not yet a specialized profession in the colonies, the design of buildings was left either to amateur designers or to carpenters who were engaged in translating architectural handbooks imported from England. Inventories of libraries shows an astonishing number of these handbooks for builders, and the houses built during the eighteenth century show their influence. Nevertheless, most household architecture of the first-quarters of the eighteenth century displays a wide _ of taste and freedom of application of the rules laid down in these books. Increasing wealth and growing sophistication throughout the colonies resulted in houses of improved design, whether the material was wood, stone, or brick. New England still favored wood, though brick houses became common in Boston and other towns, where the danger of fire gave an impetus to the use of more durable material. A few houses in New England were built of stone, but only in Pennsylvania and areas nearby was stone widely used in buildings. An increased use of brick in houses and outbuildings is noticeable in Virginia and Maryland, but wood remained the most popular material even in houses built by wealthy landowners. In the Carolinas, even in closely packed Charleston, wooden houses were much common than brick houses. Eighteenth-century houses showed great interior improvements over the former ones. Windows were made larger and shutters removed. Large, clear panes replaced the small leaded glass of the seventeenth century. Doorways were larger and more decorative. Fireplaces became decorative features of rooms. Walls were made of plaster or wood. White paint began to take the place of blues, yellows, greens, and lead color1s, which had been popular for walls in the earlier years. After about 1730, advertisements for wallpaper styles in scenic patterns began to appear in colonial newspapers.
Answer: The improved design of eighteenth-century colonial houses.

Article: In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear.
Answer: The songs of whales.
