CONVERSATION III.

_Uncle Philip tells the Children about Animals that are

Tailors._

"Uncle Philip, we are very glad to see you, and we think we have found

out something to ask you, about a kind of work which men do, that no

other animal can accomplish. As we came along this morning to visit

you, and were talking of what you had told us of insects that, like

carpenters, could saw wood and bore holes in it, we passed by the

tailor's shop, near the church; 'and now,' said we, 'we have found out

something which will puzzle good Uncle Philip: there are surely no

tailors among the lower animals; so we will ask him to-day to talk about

creatures that can cut out cloth and sew it up with a needle.'"

"Ah, my dear children, there are a great many things which would puzzle

Uncle Philip. I do not know every thing; nor do I suppose that I can

find _every_ trade in the world among the dumb creatures which God has

made. But you have made a bad choice of a puzzle this morning, my boys;

for there are tailors among the inferior creatures, and some pretty nice

ones, too; at any rate, they always cut so as to fit exactly."

"Why, Uncle Philip! You do not mean to say that they can cut out

_cloth_, and then sew it up again with a needle and thread!"

"No, boys; I do not think it is to be expected that they should take

a pair of shears and cut a piece of cloth, or put a piece of thread

through the eye of a steel needle; any more than we expect the insect

that saws, to go to the cabinet-maker, and borrow his tool to work

with. But with the instruments which God has given to them, they will

cut what is cloth to them, the leaves of trees and flowers, and will sew

them together too: and, now I think of it, there is one that will cut

his garments out of our cloth."

"Pray let us hear about them, Uncle Philip."

"Softly, boys, softly. I have two things to say to you before I begin.

In the first place, I am very glad to hear that you think and talk among

yourselves about the things which I tell you: and in the next place, I

know that you love _me_, and, therefore would not wish, by _puzzling_

me, as you call it, to produce mortification or vexation; nor do I

think that I should have felt either vexed or mortified had I not been

able to find tailors among the lower animals; but I do not wish you to

take pleasure in puzzling people; for it is very apt to produce in you

a feeling of triumph, and to make you vain: and you must remember that

for _one_ of your questions which cannot be answered, a _thousand_ might

be put to you, of the answer to which you would be ignorant. No man, my

dear boys, knows every thing. Wise men talk with each other, that they

may learn from each other; and the wisest are not ashamed to acknowledge

their ignorance of some things; and I believe they take very little

pleasure in puzzling. It is our duty to learn all that we can, and to be

always willing at a proper time to teach others what we know."

"Thank you, dear Uncle Philip, for your advice. We did not mean to

triumph over _you_, if you had not been able to tell us of tailors among

the animals. But we see that you are right. We might get a foolish

habit, which would do us harm."

"Exactly what I meant, boys; and now let us begin. And first we will

talk of the cutting out, as the tailor always does that before he sews.

There is a kind of bee[1] which, like some of the insects we have

already spoken of, is furnished with a borer. With this she forms a

round hole, like that made with an auger or gimlet, in a hard-trodden

path, or sometimes in a piece of soft decayed wood. It is in making her

nest in this hole that she plays the part of a tailor, for the nest is

made of leaves, sometimes taken from the rose, at others from the birch,

ash, or other trees. The little creature cuts them commonly, and I

believe always, into two shapes. They are either half-oval, that is,

half the shape of the bowl of a spoon, or round, and are of different

sizes. Sometimes she makes a mistake in the size, and when she finds it

out, she alters it. These leaves are prepared to line the hole which

she has bored, and she begins with the largest pieces; taking them into

the hole, she winds around in it, until she has spread very smoothly a

tube of leaves the whole length of it; she then closes up one end of it

by rounding it off and doubling the pieces of leaf one over another.

In this case she sets about making her _cells_. She takes three of her

half-oval pieces which have been cut to fit, and contrives to roll them,

so that the edge of one piece will just lap over the edge of the next;

these, when she has finished rolling them, make the hollow of the cell,

which is not quite an inch high. She next turns up the ends of these

pieces, which are cut to fit, so as to form the bottom: she then sets to

work with three other pieces rolled in the same way inside of the cell

just finished, turning up their ends as before to form the bottom; and

within these she again works three others, so that her cell, when it is

done, is of nine thicknesses of leaves. And you see why, though she cuts

the pieces of the same shape, they are not all of one size: they are

of three sizes, so as to make the cells within each other smaller and

smaller."

"But, Uncle Philip, you have not said any thing about the round pieces

which she cuts; how does she use them?"

"I will tell you: after she has finished one cell she lays an egg in it,

and fills it all round with food nearly liquid; now as the cell is lying

down on its side, all this liquid food would run out if it were not

corked up, and the bee therefore uses her circular pieces to stop up the

cells."

"And does she really make these round pieces to fit the cell?"

"Yes, boys, exactly; and they are cut too as regularly as if they had

been first measured and marked with a pair of compasses. And, more than

this, the little creature will fit one in in less than a minute. But the

most curious thing is, that sometimes she will fly off to a distance

to get this round piece, and bring back one which will exactly suit;

so that it really seems as if she carried the size in her head. After

finishing one cell she will make another, until she has completed as

many as she wants; and then, as she always builds them one upon another,

they appear like a parcel of thimbles stuck into each other and put into

a case: and here is a picture of it."

[Illustration: Rose-leaf-cutter Bees, and Nest lined with Rose-leaves]

"This is very wonderful, Uncle Philip; and it does seem like cutting out

pieces to fit."

"Very true: but this is not the only cutter-out of leaves among the

bees. There is another kind, called the poppy-bee,[2] because it uses

the scarlet leaves of the poppy-flower to line its cell. It makes its

hole in the ground, as smooth and regular and polished as can be, and

then proceeds to line it all around with pieces of the leaves, and cuts

them to fit as she goes on. If a piece is too large she will trim it

down to the proper size and shape, and always carries away the scraps.

Now if you should take a pair of scissors and try to cut the leaf of a

poppy-flower, you would wrinkle it, but this little workman will spread

out what she cuts as smooth as glass. When she has lined this hole

throughout, and carried the lining out beyond the entrance, she fills it

with honey and _pollen_, or bee-bread, as it is called, about half an

inch high, lays an egg, then folds down the leaves on it, and finally

fills the upper part with earth."

"Then she was not working for herself?"

"No; she was providing a house for her young, and God has taught her

thus to take care of it.

"I will now tell you of another little workman, which I have heard

called the cloak-maker, because it makes for itself a mantle which

really appears very much like a cloak; and, stranger still, this cloak

is lined throughout with silk."

"Can it be possible, Uncle Philip?"

"Listen, and you shall hear. These mantle-looking cases are made by

the _larva_, as it is called, or grub of a little moth which forms a

covering of pure silk; this silk it spins from itself; it is not woven

so as to appear like our silk, but still it is real silk, and is worked

into a great many thin scales, which lap over one another like the

scales of a fish. But this is only the lining of the cloak. This little

tailor is the field-moth, which first eats what it wants from a green

leaf, and then, from the thin membranes left, sets about making its

mantle: and it makes it of two pieces cut out and joined together with a

seam, just as a tailor would make it."

"How does it go to work, Uncle Philip?"

"Why, I will give you the account as it was given by a gentleman[3] who

was very fond of observing insects, and who watched one of these little

creatures. He says that from the thin membrane of the leaf it first

cut two pieces just equal in size and of exactly the same shape; each

of these pieces was to form one-half of the cloak, and this he says was

done wonderfully fast. He noticed, too, that one end of each piece, that

which was meant for the bottom of the cloak, was just twice as long as

the other end, which was the top. The insect then placed itself between

the two pieces while they were lying flat; it afterward brought the two

sides where the seam was to be, together, and fastened them at certain

places, still leaving, however, considerable spaces open. It then began

to turn and twist its body about in all directions, until it moulded

the pieces into a hollow form to fit. When it found that it would fit

its body, it brought the edges of the seam close together through the

whole length, and contrived to sew or fasten them so neatly together,

that when the gentleman looked, even with a magnifying-glass, he said he

could hardly find the seam. The whole was lined with the silk spun from

itself, and was finished in about twelve hours."

"Why, this little workman is the strangest of all: but, Uncle Philip,

you said there was one of these animal tailors that cut his garment out

of _cloth_: pray tell us of him."

"When I said that, boys, I was thinking of the clothes-moth.[4] They

make their coats of wool commonly taken from our cloth, and silk drawn

from their own mouths; and the strangest thing concerning them is,

that when they outgrow their clothes they will piece them to make them

larger. Suppose the insect wants it longer, it adds a new ring of wool

to the end: suppose it wants it wider, it slits the case or garment, not

from one end to the other, for this would leave it naked, but it splits

it half-way down the sides, and when it has filled it in with proper

pieces, it splits the remaining half, and puts other pieces in them.

There is another curious thing about this tailor: it always makes its

coat of the same colour with the cloth from which it takes the wool; so

that if it has first made its garment of a piece of blue cloth, and is

placed on a bit of red cloth when it wishes to enlarge it, you will see

its work exactly, for the pieces which it puts in will be red. This is

the little fellow, boys, which does so much mischief to our clothes."

"Well, Uncle Philip, one can almost forgive his mischief for the sake

of his ingenuity. But you have said nothing yet about _needles_; how do

these little creatures sew?"

"Why, they have what serves as a needle to them: but I can tell you of

another animal which sews with a needle a great deal plainer to be seen

than that of these little insects."

"Pray let us hear of him, Uncle Philip."

"I must go among the birds to find this workman. There is a kind of

starling, called the orchard starling,[5] about which, Mr. Wilson, a

gentleman who has written a great deal concerning the birds of our

country, gives a very curious account. He says that this bird commonly

hangs its nest from the twigs of an apple-tree, and makes it in a very

singular manner. The outside is made of a particular kind of long

tough grass, that will bend without breaking, and this grass is knit

or sewed through and through in a thousand directions, just as if done

with a needle. The little creature does it with its feet and bill. Mr.

Wilson says that he one day showed one of these nests to an old lady,

and she was so much struck with the work that she asked him, half in

earnest, if he did not think that these birds could be taught to _darn

stockings_? Mr. Wilson took the pains too to draw out one of these

grass threads, and found that it measured thirteen inches, and in that

distance the bird who used it had passed it in and out thirty-four

times."

"Why, this was sewing, sure enough."

"Yes; and I saw, when I was in the West Indies, another kind of

starling[6] which will cut leaves into a shape like the quarter of

an orange-rind, and sew the whole very neatly to the under side of a

banana-leaf, so as to make one side of the nest. But, boys, there is

another most beautiful little bird, which is called the tailor-bird,

because it sews so well.[7] It first picks out a plant with large

leaves, then it gathers cotton from the shrub, and with the help of

its fine long bill and slender little feet it spins this cotton into a

thread, and then using its bill for a needle, it will sew these large

leaves together to hide its nest, and sew them very neatly, too."

"Why, dear Uncle Philip, this is the most wonderful tailor of them all."

"He is, indeed: but, my children, what do we learn from all that I have

been telling you? Who made these little creatures with such curious

skill, and taught them to work so well? It was the same God who made us;

for such wonderful things never came from what people call _chance_.

Chance, boys, never made any thing: and how very wise he must be to

form such nice little workmen; and how very good thus to teach them how

to take care of themselves. The Bible says, truly, that '_his tender

mercies are over all his works_.' And I think, boys, we may learn

another thing: it is, not to be so very proud of what we know; for I

rather suppose that we shall often find that the lower creatures around

us understood many of our trades long before we found them out."

"Yes, Uncle Philip, it is likely that these little fellows you have been

telling us of this morning were the first tailors in the world."

"Very likely, very likely indeed, boys. But now I must bid you good

morning; for here comes our good clergyman, and I am going with him to

see a poor sick woman."

"Good morning, Uncle Philip; we will come again on Saturday."
