"I suppose the worms didn't know that it belonged to the mulberry family," said Clara, "and I don't see now why it does." For reply, her governess read: "'The sap of the young wood and of the leaves is _milky_ and contains a large proportion of caoutchouc.'" "Oh!" exclaimed Malcolm; "that sounds just like sneezing. What is it, Miss Harson?" "Something that you wear on your feet and over your shoulders in wet weather; so now guess." "Overshoes!" replied Clara, in a great hurry. "How many of them do you wear over your shoulders at once?" asked her brother. "And it must be a queer kind of sap that has overshoes in it. Why couldn't you say 'India-rubber'?" "And why couldn't _you_ say it before Clara put it into your head by saying 'Overshoes?" asked Miss Harson. "Clara has the right idea, only she did not express it in the clearest way. The sap of the caoutchouc, or India-rubber, tree is the most valuable yet discovered, and, as it is of a milky nature, it can very properly be brought into the present class of trees." "Is _that_ a mulberry too?" asked Clara, who thought that the size of the family was getting beyond all bounds. "It is not really set down as belonging to the bread-fruit family," was the reply, "but it certainly has the peculiarity of their milky sap. However, as I know that you are all eager to hear about the bread-fruit tree, we will take that next. This tree is found in various tropical regions, but principally in the South-Sea Islands, where it is about forty feet high. The immense leaves are half a yard long and over a quarter wide, and are deeply divided into sharp lobes. The fruit looks like a very large green berry, being about the size of a cocoanut or melon, and the proper time for gathering it is about a week before it is ripe. When baked, it is not very unlike bread. It is cooked by being cut into several pieces, which are baked in an oven in the ground. It is often eaten with orange-juice and cocoanut-milk. Some of the South-Sea islanders depend very much upon it for their food. The large seeds, when roasted, are said to taste like the best chestnuts. The pulp, which is the bread-part, is said to resemble a baked potato and is very white and tender, but, unless eaten soon after the fruit is gathered, it grows hard and choky." [Illustration: THE BREAD-FRUIT.] "So Edie's 'loaves of bread' are green?" said Malcolm, rather teasingly. "That's because they grow on a tree," replied Clara. "Our loaves of bread are raw dough before they're baked, and they are grains of wheat before they are dough."
