They are very remarkable creatures. A well-trained Collie obeys the shepherd perfectly, and can bring a large flock of sheep to him or guide it in any direction that he orders. Here is a coloured photograph of a Collie dog. And lastly we have a sheep market, similar to the cattle market which we visited a moment ago. These are the principal rural occupations of Britain, the growing of corn and the tending of cattle and sheep, but there are others, although on a smaller scale. [Sidenote: 42. Hop Garden.] Here, for instance, we have a hop garden, where the creepers known as hops are grown upon poles, and supply a little fruit which, when dried, is used for the purpose of giving flavour to beer. Hops are picked in the hot weather, and a great number of people are required for the purpose. These people are, for the most part, got from the great city of London, for the part of England in which most hops grow is close to London. Once a year the very poorest of the poor people of London are carried out by train, and they camp for two or three weeks in tents in the hop country. [Sidenote: 43. Apple Tree in Bloom.] [Sidenote: 44. Apple Blossom.] This is an apple tree in blossom. Later in the year it will bear a fruit which is used for the purpose of making a drink called cider. There are whole orchards of such apple trees, presenting a very beautiful sight in the spring-time when they are gay with blossom. Here is a colour photograph of apple blossom; you may easily imagine that when these flowers deck the trees the whole landscape is brilliant, not so much with green, as with pink and white--indeed, one of the great differences between England and the tropics is that in addition to green there is so much brilliant colour in the foliage. Not only have you these orchards of white and red, but the grassy fields are at times all golden with flowers that are called buttercups and daisies, and, as we shall see presently, the trees in the autumn turn from green to brilliant shades of brown. [Sidenote: 45. Apples.] Here is a basket of apple fruit, each with a rosy cheek on its green skin. In Britain other fruits take the place of the mango and guava, which are unknown in the north.
