Then it is an interesting sight to see the old birds training their young ones to fly, by getting up above them and flapping their wings a few times until all the young ones imitate them. Then they hop from one twig to another, still flapping their wings, and the young ones follow suit and begin to find that their wings help them to balance; and finally they jump from one branch to another for some distance so that the wings support them in their effort. The young ones very soon find that they are able to use their wings for flying, but it is all done by degrees and by careful instruction. Then a large number of our birds do not live all the year round in England, but they go off to Southern climes such as Africa when the winter comes on; but they generally turn up here at the end of March and make their nest during the spring. Nightingales arrive early in April; wagtails, turtle doves, and cuckoos come late in April; woodcock come in the autumn, and redpoles and fieldfares also come here for the winter. In September you will see the migrating birds collecting to go away, the starlings in their crowds and the swallows for the South, and so do the warblers, the flycatchers, and the swifts. And yet about the same time the larks are arriving here from the Eastward, so there is a good deal of traveling among the birds in the air at all times of the year. How many of our American Scouts are able to supply from their observation all of our native birds to take the places of these mentioned in this lovely paragraph? Everyone should be able to. _Nature in the City._--This noticing of small things, especially in animal life, not only gives you great interest, but it also gives you great fun and enjoyment in life. Even if you live in a city you can do a certain amount of observation of birds and animals. You would think there is not much fun to be got out of it in a murky town like London or Sheffield, and yet if you begin to notice and know all about the sparrows you begin to find there is a great deal of character and amusement to be got out of them, by watching their ways and habits, their nesting, and their way of teaching their young ones to fly. OBSERVATION.
