In the nineteenth Psalm David speaks of the two great books God has given us for our instruction. In the first six verses he speaks of the teachings of the book of nature and the rest of the Psalm deals with the written Word of God.

We acknowledge and read the Scriptures as the book which reveals the will of God and His wondrous works for the welfare of mankind, but how many fail to give any time or thought to reading the book of nature! Thousands may travel and admire beautiful scenery, and derive a certain amount of pleasure from nature, just glancing at each object, but really observing nothing, and thus failing to learn any of the lessons this world's beauty is intended to teach, they might almost as well have stayed at home save for the benefit of fresh air and change of scene. The habit of minute and careful observation is seldom taught in childhood, and is not very likely to be gained in later life when the mind is filled with other things. Yet if natural objects are presented attractively to the young, how quickly they are interested! Question[p. 216] after question is asked, and unconsciously a vast amount of information may be conveyed to an intelligent child's mind by a simple, happy little chat about some bird or insect. This is admirably shown in a chapter on Education in the Life of Mrs. Sewell. I would strongly urge every mother to read and follow the advice there given.

We will now start for our garden walk. We have not taken many steps before we are led to pause and inquire why there should be little patches of grey-looking mud in the small angles of the brickwork of the house. Opening one of the patches with a penknife we find a hollow cell, and in it some green caterpillars just alive but not able to crawl. Now I see that the cell is the work of one of the solitary mason wasps; she brings the material, forms the cell, and when nearly finished lays her egg at the bottom and provides these half-killed caterpillars as food for the young grub when it is hatched, and by the time they are eaten the grub becomes a pupa and then hatches into a young wasp to begin life on its own account. One day I saw a bee go into a hole in the brickwork of the house, and getting my net I waited to capture it;[p. 217] after about five minutes the bee came out and flew into the net. It proved to be a solitary mason bee, and was doubtless forming a place to lay its egg, only, unlike the wasp, she would give the young grub pollen from the stamens of flowers to feed upon instead of green caterpillars. I remember seeing a mass of clay which had been formed into a wasp's nest by one of the solitary species, under the flap of a pembroke table in an unused room. A maid in dusting lifted up the flap, and down fell a quantity of fine, dry mud with young grubs in it which would soon have hatched into wasps, and revealed their rather strange nesting-place. I have in my collection a very interesting hornet's nest, which was being constructed in the hollow of an old tree. I happened to notice a hornet fly into the opening, and, looking in, there was a small beginning of a nest. It hung from a kind of stalk and consisted of only eight cells, each having an egg at the bottom. I captured the two hornets, and though I watched for a long time no others ever came, so I imagine they were the founders of what would have been a colony in due time.

But we have been kept a long time engaged[p. 218] with these mason wasps. Let us start for our walk. As we take our way through the garden we cannot help noticing the happy songs of the different birds, all in full activity preparing their nests, carolling to their mates or seeking food for the little ones. There is a loud tapping noise as we pass an old fir-tree, but no bird is to be seen, so we go round to the other side and trace the noise to a small hole near which a quantity of congealed turpentine shows that the bark has been pierced by a woodpecker and the sap is oozing out. I rap outside the hole and in a minute the grey head of a nuthatch appears. He is evidently chiselling out a "highly desirable residence" for his summer quarters in this cosy nook, and the hole being so small he will not need to get clay to reduce the size of the opening and plaster in his mate, which is said to be the curious habit of this bird. Do you see that hole about forty feet up the stem of the beech opposite? A nuthatch built there six years ago; I often watched him going in and out, and heard his peculiar cry as he brought food for his mate and her young ones. Next year that lodging was taken by a starling, who reared a brood there. The[p. 219] year after the nuthatch had it, and then a jackdaw built there; and each year I always feel interested to see who the lodgers are going to be.

When I was rearing the wild ducks already described, a weasel used often to be prowling near the coop, and when frightened retreated in this direction. It happened one day I was walking softly on the grass and saw the weasel playing and frisking at the root of that young tree; one seldom has such an opportunity of seeing it, for it is very shy and has wonderfully quick hearing. It was seeking about in the grass, leaping here and there, snuffing the wind, with its snake-like, wicked-looking head raised to see over the grass stems, and thus at last it caught sight of me, and in a second it darted into the hole you see there, and I thus learnt where he lived, but I have not been able to trace his history any further at present.

Did you see that snake? We have many of them on the common, and they often cross my path in the garden. Happily there are not many of the venomous kind: they are smaller than this one, and have a V-shaped mark on the head. One day in August I was sitting by the open French window[p. 220] in the drawing-room when one of these harmless snakes came close to me, looked up at me, putting its quivering little tongue in and out. I suppose it decided that I could be trusted, for it glided in and coiled itself round upon my dress skirt and seemed to go to sleep. I let it stay a good while, but fearing some one might be frightened at seeing it there, I reached my parasol and with the hooked handle softly took up the snake and laid it on the grass-plat outside thinking it would go away—but no, it only turned round and came back and coiled itself up in the same place. I found it did not mind being touched, so I stroked it and made it creep all its length through my hand—not a very pleasant sensation, but a curious experience rarely to be met with. When the cold, clammy creature had passed out of my hand it threw out a most disgusting odour, of which I had often read. I imagine it was offended at my touching it and did this in self-defence. I had at last to carry it a long distance to ensure it should not return to the room again.

Some years ago I was witness to the mode in which a snake pursues its victim. A large frog[p. 221] leaped upon the gravel walk before the windows, crying piteously like a child and taking rapid leaps; a moment after a large snake appeared swiftly pursuing the frog. At last it reached it, and gave it a bite which broke its back, and then, being alarmed, it darted away amongst some rock-work, leaving the frog in a dying state.

This bank we are passing is a favourite winter retreat for female humble bees. Early in the autumn they begin to scoop out a little tunnel in this grassy slope, and when it is deep enough to protect them from the frost they retire into it, and pushing up the earth behind them close up the entrance of the hole, and there lie dormant until the warmth of spring tempts them to come out. Then they may be found in great numbers on the early sallow, and other tree-blossoms, recruiting their strength, while they seek a place in some hedge-bank wherein to found a new colony.

The Carder bee forms its nest on the ground and makes a roof of interwoven moss, from which it takes its name. I once gathered the moss from such a nest by chance and saw the little mass of cells with honey in them. I went away, meaning to[p. 222] examine it more closely on my return, but a crow in the apple-tree overhead chanced to spy the nest and made off with it in his beak before I could rescue the honey store of the poor little bees I had so unwittingly injured.

That old tree-stump is being gradually carried away by wasps. The wood is just sufficiently decayed to afford the material of which they make their nests. You see there are several wasps busily rasping pieces of the rotten wood into convenient-sized morsels, which they can carry to the nest, there to be masticated into the papery layers of which the outer walls of the nest are formed. This walk used to have a row of grand old silver firs of great height, but each winter some of them have been blown down till only a few are left.
