CHAPTER XVII

The bear recovered from the crack it had received on the head, thrived

in its new mode of life and became one of the curiosities of the park.

It became quite tame, permitted a favored few to scratch its head, and

only occasionally hurled itself at the wire with an ugly snarl when

strangers approached the cage. Different people tried a great variety of

food upon it, but nothing seemed to satisfy it so well as the

blueberries and fish; of these it never tired.

The capture of the bear had opened up a new field of interest to Scott.

He knew the geology of the country thoroughly—could trace the origin of

almost every type of pebble to be found in the glacial drift; his

dendrology and botany had brought him in touch with all the trees and

plants, but the great field of animal life he had completely overlooked.

The bear furnished a point of contact, and he grasped the new lead

eagerly. He undertook the responsibility of feeding the bear regularly

and enjoyed studying his diet and habits. There were many good books on

natural history in the library and he soon obtained a pretty good idea

of bruin in all his relations to man and beast. He was surprised to see

how many new points of interest this study brought out and still more

surprised to find how many traces of bear he could find in the woods now

that he knew enough to look for them.

Naturally to such an active mind as his, the study and observation of

one animal could not help but be an introduction to the other forms of

animal life. The deer, wolves, minks, lynx, wild cats, skunks, otter,

coons, porcupines, woodchucks, squirrels, chipmunks, frogs, fish, nutes,

salamanders, snakes, birds and a host of others he had never dreamed of

crowded upon his attention and filled the woods with a new interest. Now

that his eyes were opened he could not walk a hundred yards without

seeing something to attract his attention. He was beginning to realize

how the old woodsman with his knowledge of woods’ life could live for

months without human company and never feel lonely.

Greenleaf had long ago discovered this secret, and could help him

greatly in his observations. Almost every Sunday when the other fellows

were enjoying themselves with the girls at the Lodge these two were

canoeing around the lake or tramping through the woods investigating

some of the denizens.

As Greenleaf expressed it: “There’s plenty of time to rush the girls

when you are cooped up in town and can’t get at the other animals.”

It came about very happily that just at the time when Scott was

beginning to get interested in the animals a naturalist came to visit

the camp and a geologist came to give the boys some field work. Scott’s

thorough knowledge of geology let him out of the class work and enabled

him to put in a large part of his time with the naturalist. The trips he

made with this interesting man lent him an enthusiasm and gave him many

practical hints which carried him easily over the preliminary stage

which is apt to be rather discouraging to the uninitiated. It carried

him to a point from which he could easily go on alone.

This new friend, Dr. Barnes, was a man of deep reading and wide

observation, a Chautauqua lecturer, and a most interesting

conversationalist. He had camped all over the north woods studying the

habits and watching the antics of the woods creatures. He was as

delighted to find a fellow enthusiast no matter how green a beginner, as

Scott was to profit by his experience and they became great chums.

The special attraction which had brought Dr. Barnes to that particular

place at that time was an opportunity to study the beaver, of which

there were a great many in the park. Two pairs placed there ten years

before had increased until they populated dozens of lakes and had built

some dams of remarkable size. The evidence of their work was everywhere

but the beavers themselves seemed to possess a wonderful faculty for

keeping out of sight, and Scott was astonished when he tried to look

them up in the books to find how little seemed to be known about them.

“Well, Scotty,” Dr. Barnes called to him one morning, “suppose we paddle

down to the beaver dam on the west arm and reconnoiter a little? I want

to look over the situation there and see if there is an opportunity to

stay down there some night and watch them work—for I believe they work

at night.”

“Very well, sir,” Scott replied, “I am free today, and shall be

delighted to go wherever you suggest.”

“I suggest,” said the doctor, “that we take lunch, explore the place

thoroughly, and, if we find it practicable, go back after supper to

spend the night.”

They were soon ready to start, and armed with a camera and two axes they

paddled swiftly down the west arm. Two deer, standing knee deep in the

water, half hidden by the reeds, watched them curiously as they paddled

past, but they were bent on rarer game, too intent to turn aside.

“They say the dam is up that little creek; it’s a cedar swamp,” Scott

said, “but I don’t know how wet it is.”

“Well, let’s land on that high point just this side of the swamp and we

can work in from there. The dam must touch that dry land somewhere.”

“There. The canoe is safe. Shall we take our lunches?” Scott asked.

“Certainly,” the doctor replied emphatically, “one of the first rules of

the woods; never get separated from your lunch.”

They climbed the steep bank to a bench which marked a former level of

the lake. It had been covered by a good stand of popple, but most of it

was now down, apparently thrown by a windstorm. Suddenly Dr. Barnes

spied a stump.

“Can it be—” he began excitedly running over to examine the stump. “Yes,

sir, that one, that one, that one, everyone of them gnawed down by the

beaver.”

He was trotting hurriedly from stump to stump. Scott hastened to examine

one of them and found it very distinctly marked with the print of teeth,

as though it had been cut off with a series of gouges with a concave

chisel. It was a very neat job.

“Just about two acres cleared clean,” he said, as the doctor puffed up

from the swamp. “I did not know they cut down such big trees.”

“Big trees!” the doctor echoed. “There’s a stump down there on the edge

of the swamp fifteen inches in diameter. We must have some pictures of

this.”

While the Doctor busied himself with the pictures Scott scouted around.

“Look here,” he shouted excitedly, “here are some regular skidways and

logging roads.”

The Doctor came on the run. “Yes, sir, well planned ones, too. You see

they cut down the tree simply to get the twigs and smaller branches. The

latter they haul down these skidways, float to their pond near the house

and keep under water so that they can peel them in the winter time. Now

let’s go look for the dam. There ought to be a beaver trail down to the

swamp.”

He was right. A well beaten trail led them down to the swamp and right

to the end of the dam. It was a queer looking structure; a low

embankment of dirt and sticks winding away across the swamp, which was

dry below the dam and covered with a foot of water above. They walked

along the top of the dam pacing the distance as they went. As they

neared the stream the dam increased in height to about six feet backing

up a corresponding depth of water.

“Two hundred and forty feet,” the doctor said, “isn’t it wonderful?”

“What is it for?” Scott asked.

“You see they had to build it so long on account of the swamp. If the

banks of the stream had been steep the dam would have been short. They

build it to keep water always around the house, which is built in the

pond above the dam. The entrance to it is under water. The wolves can’t

get into it. Besides that it gives them a chance to get under the ice

for their sticks in the winter. See that big pile of sticks out there in

the pond? That is the house. Let’s see if we can get out there.”

By walking fallen trees and wading shallow bars they finally reached the

house. It was some fifteen feet across and protruded about four feet

above the water. It was built of sticks—all of them providently peeled

beforehand—from an inch to three inches in diameter, the whole plastered

thickly with mud. It seemed perfectly solid. There were a few tracks in

the mud and a whimpering such as might be made by small pups came from

the inside, but no beavers were to be seen. They retraced their way to

the dam.

“Right there,” the doctor said, pointing to a mound of comparatively dry

moss, “we could spend the night quite comfortably. I believe that if we

break a hole in the dam so that they can hear the running of the water

they will come to fix it up.”

They made their way down the stream. There were several other dams which

had apparently been abandoned, all short, but one of them higher than

the new one. Just before they reached the lake Dr. Barnes was delighted

to find an old abandoned house.

“Now,” he exclaimed excitedly, “we’ll see what it’s like inside.”

The solidity of the structure was wonderful, but by dint of considerable

hard work with the axes they cut away half of the house, showing the

interior in cross section. It was some time before Scott had a chance to

inspect it himself for the hole was no sooner opened than the doctor

crawled into it head first; spasmodic wriggling of his legs and a series

of muffled exclamations alone told of the state of his emotions. He

stayed so long that Scott began to fear that he had moved in there to

live. He finally wriggled out very red in the face, and very jubilant.

“Why don’t you look in there?” he asked. “You can see just how they

live.”

Scott did not waste any time explaining why he had not looked in, but

crawled eagerly into the muddy opening. Much to his surprise he found

the floor of the house well above the level of the stream and perfectly

dry. The roof of the house was arched up with great skill leaving an

opening in which a good-sized man could curl up very comfortably. On two

sides there were tunnels leading down to small dirt landings almost on a

level with the surface of the water. From these the beaver could slip

conveniently under the water, still within the house, and swim out

through a submarine passage. It was certainly a very ingenious

arrangement—for they had all the advantages of living on land and at the

same time were protected absolutely from the attacks of all land

animals. The floor was covered with fish bones, which Scott learned

later had probably been left there by the mink who had made use of the

house after its abandonment by the original inhabitants—for the beavers

themselves do not eat fish.

No sooner had Scott wriggled out than the doctor crawled laboriously in

again with a pencil and envelope in his teeth to draw a sketch of the

interior. This completed and several photographs taken of the house from

all angles, they ate lunch, traced out the boundaries of the cuttings on

both sides of the swamp and paddled home to prepare their outfit for a

night in the wet moss. Dr. Barnes was all enthusiasm.

The other boys had no desire to share in the expedition, but they were

immensely interested in a way and shouted bits of advice and sarcastic

sympathy after the canoe as long as it was in range.

The long twilight gave them plenty of time, and they sneaked the canoe

along the edge of the lily pads in hope of catching some of the beavers

out foraging—for it was the time of day when they were most often seen.

As they approached the cedar swamp they observed a green popple branch

moving mysteriously and swiftly across the surface of the lake. Closer

observation showed that it was being vigorously pushed along by an

energetic beaver. They gave chase to see what he would do. He was

evidently loath to give up the prize, for he only swam the faster,

throwing quite a swell like a small tug boat. Finally the pursuit became

too hot for him and he abandoned the branch, diving under the surface

with a splash. Several times he came up to reconnoiter, diving again

almost instantly. Each time he dived he struck the water a blow with his

broad flat tail which sent his head under with a jerk and made a report

easily heard a half-mile away over the still water.

They paddled the canoe over toward the shore again to see if he would

recover the branch. After several false starts he took it in tow once

more and disappeared with it up the creek. When the canoe was still some

distance from the shore they spied another beaver dodging around the

lily pads. He was so intent on his own business that he did not seem to

notice the silently moving canoe. He was evidently making his evening

meal off of the yellow lily buds. Rising head and shoulders above the

water, he would devour a bud with great relish, sink silently into the

water and come up alongside of another juicy bud. They followed these

maneuvers for some time before he took alarm, dived with a loud splash

and was seen no more.

They scouted around cautiously but failed to find any more night

marauders.

“We’d better go ashore now,” the doctor suggested, “and fix things up

for the night. It may get dark before we are ready.”

They pulled the canoe up on the marshy shore and made their way up the

stream to the spot they had picked in the morning. The mound of moss

proved to be none too large, but the blankets were finally arranged so

that they thought they could spend the night in comparative comfort.

“Now for a hole in the dam,” the doctor said, with suppressed

excitement. “Where’s the ax?”

They soon found that a pick would have been more effective. The dam was

built even better than they had thought. The sticks were woven together

and plastered with a solidity that astounded them. A breach some three

feet long and a foot deep was finally made, and the water came pouring

out with a rush which must have appalled the beavers.

“There,” said the Doctor panting from his exertions, “that ought to

bring them all to the rescue. We must keep very still and wait

patiently.”

“Do you think they can smell us here?” Scott asked anxiously. “We are

pretty close to the break.”

“No, I don’t think so; most of these water animals rely more on sight

and hearing than on smell. They may be suspicious for a while, but they

will have to fix it for fear of having their pond drained.”

It did not take the beavers long to discover the break in the dam. The

watchers had scarcely settled themselves on their blankets when they

heard the distant plunk of a diving beaver in the pond. There was a

moment of tense silence and then another plunk nearer.

“Here they come,” the doctor whispered excitedly. “Keep quiet.”

The approaching beaver evidently wanted to investigate the leak, but had

no idea of being drawn into an ambush. He circled cautiously around at a

distance, diving nervously at short intervals, till, finally assured

that there was no danger, he swam boldly up to the breach and nosed

around it. They could see the faint glimmer from the little roll of

water he pushed along in front of him and once he passed so close to

them that they could hear his heavy breathing. Then he swam quietly

away.

“That must be the watchman sent to reconnoiter,” the Doctor explained.

“He has gone back to report on the break.”

He must have made a very lengthy report or had some trouble in

convincing the others, for it was a full hour before they heard anything

from him. Then once more they heard the distant “plunks.” Much to their

disappointment he came alone. He repeated the same performance as before

and disappeared once more.

“He must have forgotten some of the details,” Scott muttered.

Another hour of waiting and he came again. He seemed worried over the

escaping water but showed no inclination to repair the dam.

The next hour it was the same thing. “He must patrol this place all

night,” Scott suggested. “Do you notice that he strikes the hour almost

to the dot?”

“Yes,” the doctor murmured, a little sleepily. “They must come to repair

that dam pretty soon. We ought to have made the hole deeper.”

It grew cold in the swamp and each hour seemed colder than the preceding

one. The dismal squawk of a night hawk or the honk of a passing blue

heron sounded occasionally above the monotonous flowing of the water. An

owl seemed to be hooting fun at them from a neighboring tree—for he

always started up just after the sentinel had made his round, and along

toward morning the occasional scream of a coon just returning from his

night’s marauding, pierced the stillness. The crowded quarters on the

little mound of moss were very hard on cramped muscles and the lack of

industry on the part of the proverbially busy beavers was thoroughly

disappointing. Scott was beginning to feel his enthusiasm in the beavers

oozing away.

The dawn, that chilling interval between night and morning, was stealing

upon them and soon the streaks of light began appearing in the eastern

sky.

The Doctor stretched himself as much as he dared without getting his

feet in the water and sat up shivering. “I guess we have seen about all

we are going to see this trip,” he said despondently. “We might as well

go down here on dry ground where we can stretch ourselves and cook

breakfast.”

“Don’t you suppose they are going to fix that blooming dam sometime?”

Scott asked in disgust.

“Surely they’ll fix it,” the doctor replied confidently; “maybe they

work in the daytime. We’ll come back again sometime, break the dam wide

open, and hide on a platform in the trees. Maybe that would get them.”

Scott made a mental resolve that he would not make one of the party in

the tree, but the little doctor’s ardor was so little dampened by the

failure that he soon felt ashamed of himself.

“After all,” the doctor said reassuringly as they paddled back to camp,

“we did not fail altogether. All scientific facts are collected slowly,

one by one, and each new one is so much added to the sum of human

knowledge. We have seen a beaver patrolman on his beat—even had some

water splashed on us by him—and that’s more than any other scientist I

know can say.”
