Toads do not lay their eggs in great masses, as frogs do, but arrange them in strings about four feet long and an eighth of an inch wide. Each of these strings consists of two rows of eggs fastened side by side together. The tadpoles are very much like those of the frog, the chief difference being that they are rather smaller and blacker.
Newts
All through their lives newts keep their tails, instead of losing them when they cease to be tadpoles.
You can find newts in plenty all through spring and summer by fishing with a small net in any weedy pond; but you will find that they are not all alike. Some have wavy crests running all along their backs; others have none; and some are brightly colored while others are plain olive green all over. Often in the woods in certain parts of the United States you will meet with little newts traveling about on the damp old leaves; and they are very conspicuous because of their brilliant vermilion color. These are young green newts which come out of the water, live ashore for a year or so in the red suit, and then go back to the water and a green coat.
Newts lay their eggs in a very curious manner. They do not fasten them together in great batches, like the frog, or in long, narrow strings, like the toad. They lay them one by one. And the mother newt takes each egg as she lays it, places it in the middle of the narrow leaf of some water-plant, and then twists the leaf neatly round it with her little fore feet, so as to wrap it up in a kind of parcel! The tadpole which hatches out of this egg is very much like that of a toad or a frog; but the front legs are the first to appear, instead of the hind legs, while the tail, of course, does not pass back into the substance of the body.
Newts swim with their tails, and very pretty and graceful they look as they move through the water. When they cease to be tadpoles, of course, they breathe air, just as toads and frogs do, and have to come up to the surface every two or three minutes to obtain it. And as long as they live in the pond they feed upon grubs and worms and tiny water-insects.
Salamanders
The curious creatures known as salamanders are related to the newts, and begin their lives in just the same way. But after they have ceased to be tadpoles they only visit the water for two or three weeks in the spring.
The most celebrated member of this group is the spotted salamander, which is found in Central and Southern Europe, and also in Algeria and Syria. When fully grown it is about eight inches long, and may be known at once by the two rows of large yellow blotches which run down from the back of its head, right along its body, to the very tip of its tail.
In days of old it was thought that the salamander had the power of walking through fire without being burnt! And it was also supposed, if it were attacked, to spring upon its enemy, bite out a piece of his flesh, and then spit fire into the wound! As a matter of fact it is almost harmless, and may be picked up and handled without the slightest danger. But the glands on its skin, like those on the toad's head and back, contain a rather poisonous fluid, which is squirted out if they are squeezed. So that if a dog were to pick up a salamander he would be quite sure to drop it again very quickly, and would most likely foam at the mouth for some little time.
