In March, 1886, the writer, a tall awkward young man fresh from the fields of Ohio, was traveling by rail through Utah. Near Provo he began to see snug farms with trees, meadows, orchards, granaries and haystacks. Some of these stacks had been cut in two with the hay knife, and he noticed with won- der the beautiful green color of the fresh cut sur- face. Calling the attention of the conductor to this phenomenon, so strange to him, he 'asked, "What sort of hay is in those stacks ! " ' i Lucern, ' ' prompt- ly replied the conductor. "And what makes it so green ? ' ' " It 7s green because that 's the color of it, ' ' sagely replied the smiling conductor, as he pocketed a cash fare and moved on about his business. At that date lucern, or alfalfa, had not spread much east of the valleys of Utah; some was grown in Col- orado, but it was a new thing there. The Utah farmers were many of them English and Danish, hence their choice of the old name lucern, while the Spanish term alfalfa had come in from Chili by way of California. Late that night the writer reached Salt Lake City and early next morning he was up ready to explore. In his rambles about the quaint old city (more old- world than American at that time with its houses of adobe, its walled gardens and orchards, its rows of towering Lombardy poplars) he came across a (3) 4 AFLALFA FARMING IN AMERICA. square devoted to the hay market. There stood awaiting purchasers dozens of loads of this curious green-looking hay. He went to a load of it and drew out a stem and chewed it to see what it tasted like. To his astonishment it tasted good, much as wheat tastes when chewed. It dissolved in his mouth and tasted as though it would nourish him. "The best country I have struck yet," remarked the "boy to himself. "If ever I get hard up here I can at least go to a haystack and eat lucern hay. I won't starve. " Curiously enough it later came to his knowledge that this first impression was true, that alfalfa hay has really in it nearly the same amount of nutrition, pound for pound, as has oats, and from oatmeal have come mighty good men. Next the boy lived for a time in Salt Lake City and cared for his uncle's cow. She was a fine motherly cow, very wide where width did the most good, low down and gentle, with a big mouth and an appetite to match it. He fed her on alfalfa hay without grain. What milk she gave ! That cow must have been a freak, for she gave some 5 or 6 gallons a day of rich creamy milk with no other food than alfalfa hay and hydrant water. Steadily as he milked the cow the respect of the boy for alfalfa hay grew. Next the boy went down into the deep mountain canyons along Green Eiver and worked there on a cattle ranch. It was a great ranch in dimension, full 40 miles in extreme length, extending from the horrid cliffs along Price Eiver to the cool heights INTRODUCTION. 5 of the Big Mesa, sloping down to the Nine Mile. Through this ranch ran a little creek called Range Creek. The soil was sandy and gravelly along the creek, not very fertile. The climate was intensely hot; often the thermometer would climb to 110° and S'tay there day after day. Cattle and horses were kept on the ranch, some 2,000 cattle at times. In the narrow sandy valley little ditches were made to lead the water from the bubbling creek, idle fox ages though once Cliff Dwellers had farmed along its banks and grown corn, which they had stored in adobe 'and stone treasure houses high up under the cliffs. Now little fields were cleared from their en- cumbering sagebrush and grease wood, the water turned on, and they were planted to corn and al- falfa. It was called lucern then; later the name alfalfa overpowered and became almost universal. At first the alfalfa did not thrive along Eange Creek. It made a small feeble growth, but it stuck. In one field especially, down close to the headquar- ters cabin, alfalfa grew the first year no more than about 6 inches high. The boy, who already had charge of the farm and general charge of all the ranch, was disgusted with it and wished to plow it up and try something else. The soil there was sandy, gravelly, open and rather coarse. An old- timer happening in at the right time counseled against plowing it. "Let it be; you may have good alfalfa there another year, ' ' he said. This advice was heeded ; the next year the alfalfa there grew so high that when the burros would walk out into it only 6 ALFALFA FARMING IN AMERICA. their heads would be visible. It produced four crops of hay and easily 8 tons to the acre. Water for irrigation was very abundant at that time in Eange Valley. It was the custom to flood the land over just before cutting off the hay and once afterward. At that time no one knew anything about soil inoc- ulation and the behavior of alfalfa was a profound mystery. It now occurs to the writer to explain the curious behavior of the alfalfa in this manner: up the canyon a mile or two was an established alfalfa field, not a good stand, but thrifty. When this field was irrigated the surplus water flowed on down to the lower field and went over that. It seems clear now that in this manner the bacteria were intro- duced from the established field to the new one. As long as the writer had connection with this ranch, some twelve years, this field continued to produce heavy crops of alfalfa, though not so wonderfully rank as the earlier growths. Doubtless the excessive irrigation leached away .some fertility, and the con- tinual removal of hay without returning any manure or fertilizer told, even on that very deep and per- vious soil. However, the last crops that the writer remembers growing on this field could hardly have been less than 5 tons to the acre. It used to be a great joy to grow alfalfa on this old ranch. Before the alfalfa came there was noth- ing in the valley to relieve the monotony of brown, drouth-stricken nature. The alfalfa fields were vividly green squares and patches, relieving the monotony of brown sage brush and bare earth. The INTRODUCTION. 7 advent of the alfalfa changed the animal life too of the canyon. Before alfalfa came there used to be little animal life save the chipmunks and lizards ; all had fled that could flee to the green mountain tops. After alfalfa deer came to stay down in the meadows all summer long ; some of them had their little fawns down there. The boy foreman used to see the old does standing deep in alfalfa nibbling daintily very early in the morning as he went up to change the water. He would not shoot them; they were his companions. Humming birds too came in great num- bers to sip the sweet nectar of alfalfa bloom. They would sit in quaint rows along the wire fence, peer- ing curiously at the boy as he passed by smiling, shovel on his shoulder. Bees he had none, else there would have been great stores of honey made there. It was joy to grow the alfalfa, because the grow- ing of it was so very easy. The method of sowing was very simple. The fields were first made fairly level. There was a strong slope so that it was easy to get water to any part of them. Then furrows were made with a common turning plow run shallow, or else with a furrow marker that made a number of shallower furrows parallel with each other. Then the alfalfa seed was sown, sometimes brushed in with a brush drag, and then a tiny stream of water turned in each furrow and kept running there for days and days, since under that burning sun one could not. count on sandy land holding moisture at the surface very long. Sometimes the alfalfa was sown in March, oftener in April. It did not make 8 ALFALFA FARMING IN AMERICA. much hay the first season, hardly any in fact; the second year was when it began to hump itself. By the second year all furrows were pretty well leveled down or washed away; then the land was irrigated by flooding. Large ditches were placed across the heads of the fields, with lesser ones transversely lower down. The head ditches were provided with dams hastily thrown up across them from the sand of the ditch bottom. Then as big a head as could be mustered was turned in and all of it turned out in one place. The irrigator got out with his shovel, often in bare feet, and helped it flow this way and that, spreading it so that it covered that part of the field with an even-flowing sheet of water a few inches deep. When it had flowed a few hours the dam was broken, 'the stream carried further along to another turnout. By this simple plan of irrigation the writer unaided one summer watered about 90 acres of land. That was a happy summer. He had a big white burro, "Old Nig," which he kept saddled most of the time. Nig knew the work about as well as the boy knew it, and he would gallop merrily up the road to the top of the field in the morning, about two miles from the cabin, stand patiently under a cottonwood tree till the work was done there; then with his master on deck gallop cheerily down to the next field, and so 'on till all the water had been given attention. There is a great fascination in working with water and the writer yet thinks irrigation farming one of the finest schemes in the world. The making of 'the hay was hard work, but not INTRODUCTION. 9 accompanied with worry, because usually no rain fell between April and September. We used to mow down the alfalfa and rake it while quite green and as soon as possible pile it up in big cocks and leave it there to dry out a while. In that hot sun and baking air the moisture disappeared very rapidly indeed, so that by the time we could get to hauling, the hay would be dry enough, and thus it retained perfectly its color, leaves and delicious aroma. Very joyous times we had at this haying, a lot of harum- scarum cowboys and ranch hands, strong as wild colts and rejoicing to see which of us could lift the largest forkful of hay. At first we simply hauled the hay on wagons and stacked it by hand. Later an ingenious Mormon boy showed us how to rig a pole stacker, and then we let the horse do the pitching. We accumulated great ricks of hay, hundreds of tons, against pos- sible severe winters. Meanwhile we were feeding alfalfa to our saddle and work horses, to poor cows and calves that would have died before green grass came had they not had this Kelp, and occasionally fattening a bunch of beef steers on it for the spring market, when fat beef brings a premium in Denver and Salt Lake City. We had no grain at all and fed only alfalfa hay, making with it very good beef indeed, though doubt- less we would have made much fatter cattle had we had corn to feed along with it. We had a few old sows on the ranch and must make provision for feeding them and their pigs. 10 ALFALFA FARMING IN AMERICA. They were astonishingly prolific sows and gave us great litters of healthy pigs, so many sometimes that we did no-t know what to do with them. The sows were kept penned up nearly the year through and during summer we simply cut alfalfa with a scythe and threw it over 'to them. This kept them in fine thrifty condition and their pigs grew but kept rather lanky on the diet. When fall came we would fatten them off with pumpkins and squashes and alfalfa. In winter time we would vary the diet by giving them dry alfalfa hay and alfalfa leaves. They throve well and it was at first very amusing to see hogs eat alfalfa hay, putting their feet on it to hold it down while they tore it apart with their teeth and chewed it as best they could. It was won- derful to us also to see what fine full udders our milk cows had. Old-fashioned milking Shorthorns they were, of the type that the fathers had. The Mormon settlers had brought with them their best family cows when they came across the range, and we had some of their descendants. We fed these cows only alfalfa hay in winter, and mostly soiled them on green alfalfa in summer, and what splendid foaming pails we carried down from the corral ! We half lived on milk and cream those days, being too busy to make butter. Sometimes we had trouble from alfalfa bloat. That came in the fall, after we had turned -the cows on the meadows and they grazed the alfalfa that had come up since the last mowing and gotten badly frosted. We used to have strenuous times with these old cows, tying sticks in INTRODUCTION. 11 their mouths like bridle bits, making them stand with their heads up a steep bank and putting cakes of ice on their distended sides. We never had one die, but learned then that frosted alfalfa is never a safe feed for a cow. Over on the Castle Valley desert were Mormon settlements, Castle Dale, Ferron, Price and other villages. They were on adobe soil mostly, a sad sort of alkaline clay, full enough of minerals but lacking in humus and life-giving properties. The first attempts of these settlers to grow grain were mostly unsuccessful; it would not -thrive, and the people were incredibly poor. Little by little they got alfalfa to growing on this alkaline soil and then with cows and pigs and poultry they managed to live quite well. t Finally one of them let the water run over his alfalfa in the winter so that it froze into solid ice over his field. This is sure death to alfalfa, unless there is air under the ice, and in the spring he had lost his meadow; nearly every plant of alfalfa was dead. He grieved over this, but set to work to see what he could get from the land and planted a part of it to spring wheat, though it had previously refused to grow wheat, and a part to potatoes, also a very uncertain crop at that time in Castle Valley. The result was a crop of wheat that made 60 bushels to the acre, a marvel to the whole valley. The potatoes made some unheard of yield, about 900 bushels to the acre, I think, and the for- tunes of Castle Valley with its sun and brilliant skies and wildly desolate plains and crags was assured. 12 ALFALFA FARMING IN AMERICA. These valleys were fertile, they would yield food for man and beast, and alfalfa was the magic sesame that made open the door to the riches of the valley. All this time the writer was becoming more and more enthusiastic over the wonderful value of the alfalfa plant. Back in Ohio was the old home farm where he had spent his boyhood. It was a little farm of less than 200 acres, charmingly diversified by little hills, rich flat meadow lands, wet and half wild, in which grew wild lilies and pink fragrant spireas. There was woodland and pasture, a run- ning stream, the Darby creek, with swimming holes in it, a big pond where he had sailed his tiny ships not so very many years before, a corn field, usually of about 15 acres, meadows in irregular patches, and an. old apple orchard that bore famously iof big red apples. On that farm too was an old man once tall but now bent and gray, weatherbeaten, seamed and furrowed from exposure, with a kindly serious face and a twinkling blue eye. That was the father. And a mother, small and agile and energetic, rather frail yet sunny and happy, ever singing at her work. That was mother. And two younger brothers did the work about the barns and went to school. These younger brothers, men now, are yet on Woodland Farm and are the writer's partners. The writer had been a very close friend of his father, and together they had planned the work on Woodland Farm before he had gone west, and now the old man remembered his boy and knew of his interest in the old place, so he used to write now INTRODUCTION. 13 and then long and careful letters telling of what he was doing, of the drains that he was laying, or the good corn that he grew. And the boy in his very first enthusiasm for the alfalfa plant sent home a package of seed by mail (that was in 1886) and asked the father to give it space and soil and care. And often in his daydreams he would ponder the question of returning some day to the old farm. He would dream idle dreams of what he might do there, how he might enrich it and plant it and maybe buy neighboring acres to add to it. Somewhat more than two years rolled away and the boy took a vacation and went back to the old home, to see the home folks, and a sweetheart he had there. It is a very joyful and rather a wonder- ful thing to come home after having been exiled to a strange land. The deserts of Utah were like an- other world, so that when the boy came to Ohio it was as though he had come to a dream world, so beautiful, and so natural and so lovely it all seemed. How eagerly he explored his old haunts, one by one ! What old memories were stirred into life as he saw the meadows, the woodland, the hill planted to corn and kept immaculately clean of weeds, the orchard, the garden; the dear old father, stooped and aged more than the boy remembered him, went right to his heart ; the mother, silvery haired now ; the sister and young brothers ! The sweetheart was of course unspeakably marvelous and wonderful, and it all was as though the boy had been born again into a new world. Soon after his arrival, as he explored 14 ALFALFA FARMING IN AMERICA. with diligence, lie asked the old man: "Father, where is my alfalfa! Did you plant that seed that I sent you?" "Why, yes, I planted it, but it did not amount to anything. This is no country for alfalfa. It may do for you in the West, but it is of no use here ; but come and see it, what there is of it." Back of the garden the old man had spaded a square rod of good clay soil and sowed his seed. He led the way and pointed accusingly to the stunted little plants scattered thinly over the ground: " There, don't you see that this thing is no good for Ohio!" The boy stood in amazement looking at it, so dif- ferent from what he had fondly hoped it might be. His father turned away and left him, but still he stood studying the situation. Soon happened along a flock of his mother's fowls; they came to the alfalfa patch and began an eager search for leaves ; one by one they plucked them off till nearly every plant was stripped bare, then walked away. " Aha !" cried the boy ; ' ' I see a light now, ' ' and he went to the well ^nd pumped a tub full of water, which he carried and emptied carefully down by the strongest root that he could find. It was early August and the land was dry. To keep away the chickens he took an old barrel, knocked the heads out of it and put it over his alfalfa plant. In a little more than three weeks he was ready to go back to his work on the ranch and he went to say good bye to his alfalfa patch. To his delight the stalk of alfalfa had thrived for its wetting and its protection and had grown out through the top of the barrel ! Joyfully INTRODUCTION, 15 the boy called his father, ' i Come here ; see what my alfalfa has done!" And the sire, amazed and be- wildered at first, stood there scratching his old gray head and smiling an amused, puzzled smile. Finally he turned and said: "Son, do you suppose that I want to grow a crop that won't grow till you put a barrel over it ? " The lad laughed and said no more, but went back to his mountains >and the alfalfa fields, remembering the one stalk of alfalfa that had succeeded and saying, "I know that alfalfa can be grown in Ohio. If one stalk will grow as that one grew, why can't a man grow a thousand? If he can grow a thousand, why can't he grow a million, why can't he cover his farm with alfalfa?" The ranch was not just the same to the boy when he came back to it, not just the same because he had ever before him the image of the sweetheart left be- hind. Yet it was a happy place, and he went tumul- tuously into the work again, strong as a young giant, eager to do, finding no day long enough for him. Now was time of happy dreams, and after a time the dreams began to materialize as he mixed mud and made "adobes," or "dobies," as the boys called them, and hauled down logs from far up the canyon, for She was coming and a house must be made ready for her. There were wonderful letters coming, too, and often the boy would be seen on Sundays sitting far up on the rocky hillside, away from the confusion and talk of the cowboys, reading the last letter that She had written, or writing one in reply to it. The work 16 ALFALFA FARMING IN AMERICA. of the ranch was much the same as it had been save that the ricks of alfalfa grew larger and larger each year and the problem of making and using the hay grew to be portentous. The mountains remained the same always, and the boy loved them deeply and climbed them eagerly, going up where never white man had been before, just to gaze off afar to other snowy ranges, and across sunny yellow valleys in the desert, beautiful from afar. All the cowboys loved him and worked faithfully for him ; every one worked as hard as he could and the cattle waxed fat on a thousand hills. In November it was that the letter came, the letter written in that familiar crabbed yet plain handwrit- ing that the father used. Nearly always the father's letters gave the boy much pleasure. He opened this one expecting it to be like the others that had come, but it was a shock to find in it a totally different note. It read like this: "My boy, I wish you to come home. Times are hard back here; hired men are no good any more. I am getting old and infirm. I need you very much. Come home and help me with the farm. I do not see how I can get along without you longer." The letter gave the boy a rude shock. All at once he realized how he loved the wild ranch with its free- dom, its responsibility, its opportunities for doing things. He loved every hill and every mesa and every canyon. Half of the canyons he had named, some of them he only had ridden through. He loved the sun and air, the yellow bunchgrass, the INTRODUCTION. 17 solemn pines. He loved the horses that he rode and the great herd of cattle in his charge, and his com- rades, rough as bears and loving as brothers. So he carried the letter in his pocket with a sad heart for a day or two, when little Billie Barnson, who was riding beside him, turned to him and said: "Joe, what in thunder is the matter with you! Has your girl gone back on you?" "No, Billie, that is not what is the matter, " and in a few words he laid bare his heart; he ought to leave the mountains, perhaps forever, and he dreaded to go. "Why, Joe, I 'm ashamed of you. ' ' "Ashamed, Billie ! Why are you ashamed of me!" "Well, Joe, if I had had a father as good as yours has been [Billie had never known his father] and in his old age he asked me to come home and help him, I'd go." That decided it. i ' I think you are right, Billie. I >m going. " " Well, I want to see you smile then." "All right, Billie, I'll go, and I'll smile too," replied the boy, and his heart grew light again as he began to turn his thoughts toward home once more, and the simple but satisfying joys of the homeland. The homecoming occurred just before Christmas time of the year 1889. It was a very joyous home- coming. The kind and rejoiced old father, the old mother happy to see her son, and the things made dear by old association, all these conspired to make full the cup of joy; and beside near by lived the sweetheart. So the boy was very happy for some days. After that he began to explore again the old farm. It was a good farm, of 196 acres, mostly 18 ALFALFA FARMING IN AMERICA. meadow and pasture land, with a fine bit of wood- land, and about 50 acres part of the time under the plow. It was farmed in the old-fashioned way — corn followed by wheat and wheat by clover and timothy. Hogs were kept and cattle; timothy hay was sold with wheat, pigs, fat steers, potatoes, parsnips, pears, grapes and a few minor items. The father was a careful man, economical to a degree, hard working and patient. He loved his land and cared for it as best he could, saving every scrap of manure and tilling the soil with diligence. He loved his animals and fed them well. His driving mare was almost too wide to get between the shafts; his cattle knew him and would stand to be rubbed and petted. It was through no lack of industry or in- telligence that the father had not of late years made the farm pay ; it was due mainly to his following an unprofitable system of farming. When the boy came home there was an old lame negro man helping do the farm work, old " Uncle Sam" they called him, a faithful old soul but slow and feeble. In the feedlot were about eight steers, maybe twenty pigs were being fattened, in the crib probably 500 bushels of corn, in the mows maybe 50 tons of hay. The boy took it all in very rapidly and a great hunger for the old ranch came over him, a hunger and a longing for its wide free life and its endless range of activities. To add to his unrest a letter followed him, a letter from the manager. It read like this: "Come back, Joe, as soon as you can. Your place is awaiting you, and more wages if INTRODUCTION. 19 you think best, and we will build the house for your sweetheart, and you shall be your own boss. Come back as soon as you have your visit out. ' ' Small wonder then that the boy soon began seek- ing to frame some explanation or excuse to offer the father, some way to tell him that he could not stay to care for the little farm, with the great ranch calling him. And the father could read the boy's mind like an open book, so one morning after family prayers he said : ' t My boy, I wish to talk business with you. I suppose you did great things in the West. You probably had 2,000 cattle there, if you say you did. I don't know, as I never saw that many cattle together and never expect to; but I wish to show you that this old farm is not played out either. Now see here, here is what we have done this year. ' ' Then he took down from the shelf his old account book and read off the items, all duly set down in black and white, the wheat that he had sold, and the hay, the pigs and the potatoes and the cattle. And together they carefully footed it all up. It amounted altogether to -a little less than $800. Eight hun- dred dollars ! It came over the boy the good salary that he had forsaken in the West and all the bright hopes of that golden land and his heart went down like lead. "What," he said to himself, "have I given up all my bright prospects, all my plans and aspirations to come back and manage a farm that does not produce more than $800 a year? Why, with such an income as that, with taxes to be paid and repairs to 'be made and all expenses to be met, 20 ALFALFA FARMING IN AMERICA. I can not so muck as keep old Uncle Sam. I must myself get out with the lantern before breakfast and feed and curry the horses and begin over again to do all that drudgery that I had only lately escaped. ' ' It was not a very worthy thought, but it added to his perplexity. The old father waited anxiously for the boy's de- cision. Very gently he said: "My boy, when you were with me we made more money than this. The farm then was in better condition and times were not so hard. I am too old now to develop it as it should be developed and I am tired. My happiest memories are of the time when I was strong enough to be called a man, and you were my boy, helping me. Now I am tired of being the man; I wish you to be the man. Won't you be the man, let me be the boy and help you?" There was silence for a little time while many thoughts passed rapidly through the boy's mind, then he came to decision. "Yes, father, I'll stay. I'll take hold of the old farm and do what I can with it. I think we can make it profit- able after a time, and you may help me." "G-ood," the old man exclaimed. "Now you go ahead and do whatever you wish to do. I'll give you chance to do it, for I'll feed the cattle and the pigs. I can feed them better than any man you can hire, and you know it." "Of course you can," replied the boy. Then : < < Father, let 's go and take a walk. ' ' "All right; where shall we go?" "Oh, anywhere; just out to look at the farm again." Together they sallied out, the father happy as a child, the son glad INTRODUCTION. 21 that it was settled, the uncertainty over, yet uneasy, feeling within him a rising tide of restlessness, an aching to get to work somewhere. They did not walk very far. Just beyond the barn was a field of flat clay land, wet, mostly poor and unprofitable. All over the field rose little clay chimneys, the work of crayfish. The boy stopped here. "Father, may I drain this field?" "Yes; it ought to have been done years ago," was the reply full of hearty encouragement. The boy went to* the village and came home with a ditching spade with a blade 18 inches long. He stretched a line where the first ditch was to be laid and began digging a long narrow ditch in which to lay tiles. How happy he was all at once! Those ranch muscles of his were in good training; mightily he dug. And as he be- gan pushing his muscles against that soil he began to believe in it, to have faith in it. And after he got down in the ditch and had rubbed the mud on him well he forgot the old ranch. When at last the ditch was dug and the tiles laid and covered there was one strip of land dry, only a beginning, true, but it was a beginning. The boy stood there that afternoon as he finished covering the tile and leaned on his spade and dreamed, and talked aloud to the old field. "Old field," he said, "some day I will make you all dry. Some day, old field, I will make your soil rich. Some day I will cover you over with clover, and with corn, and with alfalfa too. Some day, old field, out of you shall sprout and grow a home, a home for that sweetheart of mine." And 22 ALFALFA FARMING IN AMERICA. he looked at his watch; it was past 5 o'clock, so he went home and shed off his muddy overalls and went across the fields to see the sweetheart, happier than any king. Spring came in all its maze of bewildering hope and promise and beauty, as it comes in central Ohio, and the boy was supremely happy. There was just the joy of seeing God's miracles all around him, the bursting buds, the unfolding leaves, the blossoms on every twig, the tender grass hiding the dull, ugly earth, the dewdrops sparkling in the morning light and all the little birds singing cheerily their songs of gratitude and joy. There seemed something prophetic in it all, and something very wonderful, Grod's forgiveness-, G-od's fulfillment of His gra- cious promises. In a dim way the boy understood and believed, and realized his own duty in the mat- ter and bent eagerly to the task, seeking in a way to make himself partner with the Almighty to cover over the few acres entrusted to his charge with grow- ing things, with bloom and with beauty. Yes, it was the joyous seedtime when all one's hopes spring up anew and he has prophetic insight into what may be and what should be, not only of the good green earth, but of one's own soul as well. Every morning bright and early the boy was astir in the fields, with a faithful colored man, Frank, to help him. He had brought with him from Utah two bags of alfalfa seed and this he wished to sow. But the father was much alarmed. "No, my boy, we cannot afford to sow so much as that at one time. It INTRODUCTION. 23 has not been tried yet. You may have that potato patch down by the old orchard; that is good soil. Begin there and if that succeeds we will sow more later on." The potato patch had in it one-third of an acre. That was quite a coming down from his expectations, but he acquiesced and sowed the little field. Fortunately it was a good place to begin. The land was a strong clay loam, fairly well drained. It was full of carbonate of lime, for all through it were little pebbles of limestone. It was rich, for the cattle had stood there much when it was a part of the orchard. In some way or another it had become inoculated with alfalfa bacteria, perhaps because the father had grown sweet clover on the farm for years in odd corners and in his dooryard. So this alfalfa started out vigorously and grew well. The boy was delighted. He had a path well trodden where he had walked to see his first field. It settled in his mind the question of whether alfalfa would grow; he had no doubt whatever now that it would grow. Eapidly his mind went on ahead to the time when he would have 40, maybe 100 acres in alfalfa. The farm at that time had in it only about 50 or 60 acres of land that could be plowed. The rest was wet or poor or covered with trees. That summer came another boy from the old ranch, Willis. He was a wiry, slender lad, just out of his high school, and had spent about a year at ranching, getting health and strength there prepara- tory to going further with his education. He did not then dream of becoming a farmer, yet he was 24 ALFALFA FARMING IN AMERICA. as enthusiastic as the older brother over the beauty and promise of the little alfalfa field. He took off his coat and helped with the farm work and enjoyed it hugely till September came, when he went away to school again. It happened that he never finished his education in school; the confinement of the schoolroom was too much for his health, so fortu- nately for the farm he came back a few years later to be a partner, and later to have almost entire man- agement of the farm. Willis dreams dreams of his own and makes them come true, and he loyally car- ries out the plans of the writer. Woodland Farm owes its final development very largely to the en- ergy and executive ability of this younger brother Willis. And there was another brother yet, a sturdy lad, Charles, growing up at home; he grew to be the largest and strongest of them all and mightily he bent his muscle to help with the work. Later he too spent years in the West, ranching with sheep and cattle, and harvesting alfalfa hay there. Then he also came home and found on Woodland Farm ample scope for all his energies. It is true, is it not, that any work is as big as the man who undertakes that work? That first summer was uneventful save in the fact that the alfalfa grew so well on the trial patch. It was a year of drouth and the corn crop was nearly ruined, only about 500 bushels in all being harvested. The chief events were the long and delightful drives that the boy took with his sweetheart and the fre- quent walks he took to watch his alfalfa. When INTRODUCTION. 25 fall came the sweetheart and the boy drove out one day along quiet byways and gathered a buggy load of wild flowers and vines and with these decorated the sweetheart's home, and that night they were married. Next day they went on a honeymoon jour- ney, with the same old horse and buggy, out again into the country, driving slow beneath the old oaks that overarched the road, and more than ever the boy resolved that his life should not be a failure; that in some way he would strive mightily to be worthy of her, who had been an inspiration to him since she was a merry child of eleven, with sunny curls hanging down on her shoulders. And as soon as they were married he began digging for the foun- dations of a little cottage in the corner of the wood- land, a cottage where she might be mistress. All winter whenever it was warm enough he worked on the cottage, so that it was done nearly altogether by the labor of his own hands saving that the sweet- heart 's father came to help now and then. In June they moved in. All was fresh and new and clean, the whole air was full of hope and life was very joyous then. That spring they sowed another field to alfalfa, this time a little field of about 3 acres. And this field taught a much needed lesson. It began down by the creek where the land was low and wet, ran on up over a little hill where the land was dry and filled with limestone gravel, extended on back over some flat cold poor clay. And on only one acre of the three did the alfalfa thrive; that acre lay on Zb ALFALFA FARMING IN AMERICA. the rich dry hill, full of limestone pebbles. Down by the stream the alfalfa was weak, sickly, soon taken by the crowding grasses and weeds. Back on the flat wet poor clay it amounted to very little. On the dry rich soil full of carbonate of lime it thrived beautifully. So there the boy stood and pondered; the lesson was plain, though unwlecome. "It is evi- dent that this farm is not ready for alfalfa," he said. "I'll make it ready. I'll drain the wet land. I'll enrich the poor land. I'll grow alfalfa; some day I'll have 40 acres of it, but not so soon as I thought I would." So then began the work of lay- ing tile underdrains in earnest. The father had laid many in his day, but not nearly enough, judging by the new standard that alfalfa set up. And that fall the kind old father died, died in a peaceful and happy sort of way, as almost anyone would be glad to die. He had been fairly well that summer, and had insisted in helping in the hay field, raking with the horse rake and cheerily, almost glee- fully, showing the men that he was by no means worn out. One morning he arose early, as was his habit, and went out to work in his garden before the breakfast time, and there the boy had his last talk with the old man, and arranged with him about going to the fair soon to come off. After breakfast the father went to the barn and hitched his gentle mare Daisy to a spring wagon and got ready to go to the village on some errand, probably to take some vegetables to market. When the horse stopped at the front gate, coming from the barn, no one seemed INTRODUCTION. 27 with her, and when the women of the house went out to see they found the old man lying in the wagon as though peacefully sleeping, with a half smile on his lips, dead. It was a fitting end. He had lived a strenuous life, he had been good, he had been kind ; he had been builder not destroyer, and wherever his foot had been put down there rich grasses and clovers had sprung up. The writer makes no pretense of being as good or careful a farmer as his father was. We try to fol- low in his footsteps, that is all, and we do things in a larger way than he in his old age cared to do them. Yes, the father was gone, and with him the safe counselor, and the boy all at once realized how much he had depended upon this counsel. He could do as he pleased now, but he was not glad of the chance. He would have been very glad indeed if he could have had the continued company of the old father. He took account of stock. The farm was not pay- ing ; the crops that grew upon it when all sold could not possibly bring money enough to make it a busi- ness worth while. Much of the land was too poor to be profitable. The little alfalfa fields paid well, but they were but small spaces after all ; the rest of the farm was mostly unfit for alfalfa. The farm needed enriching, needed further drainage. If ever it paid it must be made rich. How! Well, there was stable manure. The boy knew about that; the old father had been a most careful user of manure ; he saved all that he could, but he fed his cattle out in the woods where the manure was largely wasted. 28 ALFALFA FARMING IN AMERICA. The boy reasoned : ' i Our practices are wrong. We sell off timothy hay and wheat, and thus load by load we sell away the fertility of the farm, and what we do feed is largely wasted, as we do not get the manure. Now if ever we build this farm up we must feed on the land the crops that we grow upon the land. And if we make any money in feeding animals we must feed younger animals than we have been feeding. We must feed some sort of babies. Now what shall it be?/' Then he thought of the lamb. "Why, here is the lamb," he said. "He is a baby, a gentle little fellow. One can put him in the barn, can feed him there in- shelter. His manure will all be saved in good order and can go direct to the fields with no wastage, and from the feed given him one ought to make good gain and thus make money. ' ' He had already a little flock of ewes which were his pets and his darlings. To them he added now a little bunch of 200 feeding lambs, building a shed to hold them. As he had no money only what he borrowed, he bought the small- est and cheapest lambs that he could find. They were natives, fairly healthy, and weighed 55 Ibs. when he put them in the sheds in November. He had carefully dipped them in a half barrel, and had himself as thoroughly dipped as the lambs, so they werje free from ticks. All winter he fed them care- fully, every feed with his own hands. Not knowing anything about feeding lambs, he had written to Prof. E. W. Stewart to get his advice as to how they ought to be fed, and he had told him how to INTRODUCTION. 29 compound a ration with wheat bran, oilmeal, corn and mixed timothy and clover hay. He had too little alfalfa hay yet to make much show in the feeding barn. The lambs throve; they became very fat in- deed and in May weighed 108y2 Ibs. In fact in all the years that lambs have been fed on Woodland Farm no such gain has since been secured, which simply shows that a greenhorn may do as well as an expert, if he has his heart in it and is earnest and careful. The boy had kept careful account of what the lambs had eaten so he knew what the gain had cost him. When he had figured it all up he found that he had made a clear profit from feeding these lambs of $115, the first real profit from Woodland Farm since his new venture in manage- ment. It was a small sum, yet mightily it encour- aged him. And then he dreamed another dream, out there on the sunny side of the barn. Thinking it over, he said: "Some day we'll feed a thousand lambs on this farm." But he told no one that, not even his wife, for all would have smiled in derision, for had he not bought part of the hay that he had fed this first 200? But there was more manure to haul out than ever before, and it was put where corn would be grown and where alfalfa might be expected to succeed, and more alfalfa was sown. Wherever the manure had been put out and the drains laid the alfalfa suc- ceeded. Inoculation took care of itself on Woodland Farm after the first start, because of the use of manure made from alfalfa hay perhaps, and every 30 ALFALFA FARMING IN AMERICA. little field added to those first started succeeded in almost direct proportion to the amount of manure used and the thoroughness of the underdrainage. The next winter 300 lambs were fed, then 350, then 350 again, and then a larger barn was built and 700 were fed. The work grew easier and easier; wheat was dropped from the rotation, and no more timothy seed was sown. Lamb feeding promised profit, so finally it was resolved that lambs would be fed and crops grown that lambs liked, and nothing else. Meanwhile Willis and the writer bent their backs energetically in the ditches, draining more and more land, and hiring men to dig what they could not. Charlie, too, growing up a stalwart boy, helped cheerfully, and the three brothers were full of faith. And yet neighbors smiled, and some there were to sneer. It is true that when the new barn was built with a mow that could hold 100 tons of hay men asked smilingly if we thought we could borrow money enough to buy hay enough to fill it, and went off laughing when we declared that we would fill it from our own alfalfa meadows some day. No one else in the country was trying to grow alfalfa, so far as we knew, no one else in Ohio, though there was some grown in Onondaga Co., New York. Well, we filled the barn at last, and had an overflow. We fed a thousand lambs as we had dreamed, and we fed 1,200. We had learned how at last. Lamb feed- ing is an art, a science ; it is not yet all learned. It had not all been smooth sailing, this lamb feed- ing. More than one disaster had overtaken us. INTRODUCTION. 31 There had been bad years, low prices, diseased lambs, all sorts of troubles. Grimly we had held on. 1 ' We can ?t afford to change now, ' ' we declared. * l We have made too many mistakes in what we are doing. To change now would be to lose all we have gained by making these mistakes; we don't have to make the same mistakes the second time." So we held on, confident that our scheme was a safe and reason- able one, based on alfalfa growing, the alfalfa fed to lambs, the manure put out for corn, the well en- riched corn stubble sown to alfalfa, often with addi- tional phosphorus and as much as possible of the corn and alfalfa fed 'back to lambs again. But during these years we were in debt, a little at first, but steadily the debt grew. We owed for labor to dig drains, we owed for labor and materials to build fences and barns. We did all the labor that we could do with our own hands, but we were too im- patient to wait to develop the place ourselves. "Farming either is or is not a business proposi- tion, " we declared. "If it is a safe business propo- sition this thing will pay some day, and if it is noshown in alfalfa culture in Virginia at this time than in any other state along the Atlantic seaboard. Of the southern states Alabama, Mississippi, Ark- ansas and Louisiana are doing most with alfalfa, HISTORY. 75 Louisiana perhaps leading. Alfalfa revels in alluvial soils rich in lime. These soils are found along the deltas of the Mississippi, Arkansas and Red rivers. A great per cent of the state of Louisiana is adapted to alfalfa growing once it is drained and the soil made ready. Mississippi has alluvial "buckshot" soils along the western side and limestone black soils along the eastern side. In each of these soil types alfalfa thrives. It is a remarkable fact that lands that can be bought for $25 to $50 per acre in these states will grow four tons of alfalfa hay per acre and the hay is worth at present writing $20 per ton. Albania has similar limestone soils and is doing well with alfalfa thereon. The common upland soils of Alabama will grow alfalfa when well limed and en- riched and it is thriving in many places where right preparation has been made. With all this encouraging evidence of the spread of 'alfalfa culture there remains much to be done. Not one acre in a thousand is made ready for alfalfa that should be made ready. Think of Iowa with her wide fields of maize, steadily growing less and less fertile because 'of the drain made upon them ; think of her herds of cattle, her sheep, her cows and swine all craving alfalfa to balance up a ration too exclu- sively corn. Think of Illinois, her high priced lands, her fields famed for riches but their fertility steadily diminishing, her need of foods rich in protein, her .need of soil building. And Indiana with her poorer soils and smaller farms needs alfalfa on every farm she possesses, and Ohio needs it more with her thou- 76 ALFALFA FARMING IN AMERICA. sands of dairy farms and her sheep farms and pig breeding farms. The same is true of Pennsylvania and New York, only the need is greater, for the farther east one goes the higher priced is hay and the more wheat bran is bought to furnish protein to make milk or grow animals. All over America just now there is a quickening of the agricultural life. Men are awakening, gaining new courage, new hope. The young have higher as- pirations than ever before; farming is coming out from the ruts; it is no longer a disgrace to be a farmer. The best brains and best thought and best blood of -the land are being devoted to agriculture. Alfalfa comes at opportune time. It fits in on every farm, once the soil is made right. It is a permanent thing. It is a mine of riches, a magazine of rich provender, a source of fertility wherewith to build animals and to build other soils. Alfalfa brings hope, courage and joy. It brings beauty to field and landscape. It covers over the scars made on the face of Nature, it stops the waste of erosion and soil leaching. Where it comes boys cease leaving the farm, bees come, and birds; the cows stand tranquil with full udders, land values advance, paint comes to the country school-house and happy children trudge along the lanes with well- filled dinner pails. And is it practical to grow alfalfa over all this region! It is practical. Alfalfa is one of the sim- plest and easiest things grown in the world. It is one of the hardiest plants known, one of the most HISTORY. 77 responsive. It is absolutely easy to grow alfalfa. There are no longer any mysteries about it. To teach the way so plain that anyone can follow and no one longer will fail is the purpose of this book. The writer is very earnest in this purpose. He repeats absolutely it is true that every farmer may have his alfalfa field if he has soil with water level down 36", or soil that may have the water level so lowered, and soil not entirely composed of peat. Sands, clays, alluvial soils, all alike yield to the magic of alfalfa, all alike robe themselves in living green, all alike yield rich forage and are in turn en- riched themselves by the alfalfa growing upon them. There are keys to unlock the most stubborn soils. Today we have those keys. No longer should any man fail to make alfalfa grow. The day of "experi- menting" with alfalfa is over. The day of surely growing it has come. If any man will read carefully the plain directions in this book, will read and heed, he will grow alfalfa, whether he is in Maine or Mas- sachusetts, Dakota or Dahomey. VARIETIES OF ALFALFA. The botanical name of alfalfa is Medicago sativa. It belongs to the class of plants called legumes. Its relatives are the clovers, the peas, beans and locust trees. There are thousands of kinds of leguminous plants in the world and most of them have some use. Some provide food for men, as the peas and beans; some provide forage for animals; all or nearly all have the power to enrich soils. There are more than 50 rather near relatives to the alfalfa plant. Some of them are annuals, some are biennials and some are perennials. Of them all only six have come into general use as forage plants, and of these only one or two have much merit. The descriptions following are from Prof. G. F. Freeman of Kansas: Alfalfa (Medicago sativa, Linn) is an upright, much branched smooth or slightly pubescent perennial plant one to three feet high. The branches arise from a rather woody base which crowns a long tap-root. This root with its branches may extend three to twelve, or, in rare cases, even fifteen feet deep, rendering this species very drought-resistant on account of its being able to bring up water from the subsoil far beyond the reach of ordi- nary plants. The leaves are arranged alternately on the stem and are trifoliate or three-parted, each part being slightly broader above the middle and usually tapering each way, although the apex may be frequently rounded, blunt, or even slightly notched. The pea-like flowers, varying in tint from pale, almost white, to deep reddish purple, are arranged in rather elongated loose clusters borne on the ends of the many branches. The pods are spirally twisted through one to three complete curves, forming a coil one-fourth to one-fifth inch in diameter. This pod contains from one to eight seeds. The seeds are kidney-shaped, about one- eighth of an inch long and a little more than half as wide. VARIETIES OF ALFALFA. 79 From an agricultural standpoint this species is by far the most important, being probably the most widely grown and most valu- able forage plant in the world. Yellow lucerne or Swedish clover (Medicago falcata) is a perennial plant strongly resembling alfalfa, but it differs from alfalfa in being of somewhat lower, more spreading habit and having bright yellow flowers. It is a native of northern Europe, extending into Sweden and probably far into northern Siberia. It shows greater cold resistance than the ordinary alfalfa and is less liable to winter-killing. This species is probably identical with the yellow Siberian alfalfa recently introduced by Prof. N. E. Hansen of South Dakota. Sand lucerne (Medicago media Pers.}. "There has been a dif- ference of opinion among European botanists in regard to the re- lationship of sand lucerne to other lucernes or alfalfas, viz., Med- icago sativa (ordinary alfalfa) and Medicago falcata (yellow lu- cerne.) Alefeld and other botanists unite common alfalfa, sand lucerne and yellow lucerne into a single species. Some botanists look upon alfalfa and yellow lucerne as distinct species and con- sider sand lucerne as a hybrid between them. Others regard them all as distinct species. The three forms, however, differ so widely in agricultural value and other characters that they can- not be treated together." "The ordinary distinguishing characters between alfalfa and sand lucerne are easily recognizable when the two are grown side by side." "The stiff habit of alfalfa differs from the more spreading habit of sand lucerne. The flowers of the former are bluish to violet purple, while those of the latter range from bluish and purple to lemon yellow, with many intermediate shades. The pods of alfalfa are coiled in about two turns, while those of sand lucerne are in about three-fourths of one coil. The seeds of the sand lucerne are lighter than those of alfalfa. Five hundred seeds of sand lucerne weigh from 0.8 to 0.9 gram, while the same number of seeds of common alfalfa weigh from 1 to 1.037 grams." "Sand lucerne, although a perennial like alfalfa, is not so pro- ductive in lands sufficiently moist for the latter or where it is hardy." However, in non-irrigated land in parts of Wisconsin and in Utah it is said to surpass any other variety except the Turkestan. In the moist climate of Michigan and in the irrigated land of Utah, on the other hand, it was much inferior to the ordinary sorts. Seedsmen advertise it as being hardier, more drought- resistant and better able to stand grazing than alfalfa, and say 80 ALFALFA FARMING IN AMERICA. that it will succeed on sandy soil which is too light to produce profitable crops of other forage plants. Yellow trefoil or Hop clover (Medicago lupulina L.) is an annual species and may be distinguished from alfaifa by its more spreading habit, its shorter and broader tipped leaves, by its yel- low flowers, and, finally, by the fact that the pods are not coiled, as with alfalfa, although coiled to make a single incomplete spiral. These pods also differ from those of alfalfa in being black when ripe. This species has some value in moist regions, but is far inferior to alfalfa. Bur clover (Medicago denticulata Willd.) and Spotted Medic (Medicago arabica All.), like yellow trefoil, are also annual plants and have yellow flowers. They differ, however, from all of the above-mentioned species in having burry pods. Although grown in some localities, they are of little agricultural conse- quence. Bur clover inoculates land for alfalfa growing or vice versa. They carry the same bacteria on their roots. Mellilotus, or sweet clover, also uses the same bacteria. This fact is useful since it often enables us to get hold of inoculated soil, or to sow one of the inferior clovers as a forerunner of alfalfa for the purpose of inoculating the soil or of enriching it and storing it with humus. Types and Varieties. — Alfalfa is remarkably vari- able. One can go into a field sown all of one sort of seed and select in it a hundred plants, no two having very close likeness. Much can be done and will be done to select varieties having desirable character- istics. Already the Colorado and Kansas experi- ment stations are doing considerable in this line, while other stations not so well located are also at work, notably Ohio, Minnesota and North Dakota, and the Department of Agriculture at Washington. Natural selection, -or the law of the survival of the fittest, has done much to create types. For example, VARIETIES OF ALFALFA. 81 alfalfa that has grown for some generations in hot Arizona becomes by elimination a type adapted to hot climates, and alfalfa grown for several genera- tions in Montana or North Dakota becomes also by elimination, and perhaps to some extent by muta- tion, a strain able to endure extreme cold. The practical lesson to be drawn from this vari- ability of alfalfa is that it is best to choose seed com- ing from a region in about the same latitude as one's own farm. Alfalfa from Arizona is not hardy in Nebraska. Alfalfa from Montana would doubtless do poorly in Arizona. Alfalfa from California has not always proved hardy in the East. Alfalfa from France and Germany usually succeeds in the east- ern States of America. When it fails it may be that the seed came from Algeria, up through France, and thus was in nature similar to the Arizona strain. Commenting on varieties J. M. Westgate, ag- rostologist in charge of alfalfa investigation for the United States Department of Agriculture, says: Under most conditions, especially in the alfalfa districts, or- dinary alfalfa, whether from American or European grown seed, gives quite as satisfactory results as any of the special varie- ties. In certain sections of the country, however, special varie- ties of alfalfa have been found to be more valuable than the ordi- nary forms. Of these the Turkestan, Arabian, and Peruvian varieties have been introduced through the Office of Foreign, Seed and Plant Introduction of the United States Department of Agriculture. Turkestan alfalfa was introduced into the United States m 1898, and has since been tried in all parts of the country. It has been found to be superior to the ordinary alfalfa in only lim- ited sections. It is decidedly inferior in the humid sections east of the Mississippi River, but has given somewhat better results than the ordinary alfalfa in the semi-arid portions of the Great Plains and in the Columbia Basin. In addition to its drought 82 ALFALFA FARMING IN AMERICA. resistance, it is also hardier than many of the commercial strains. Hardy alfalfa. — There have appeared during the past years several strains of alfalfa which are characterized by their hardi- ness and general ability to withstand conditions which are rather too severe for the best productions of ordinary alfalfa. There is some variation in the characteristics of these alfalfas, which may be grouped under this general head, but they agree in showing a considerable diversity in the color of the flowers, which varies from yellow to blue, green, and various shades of violet and purple. These colors are often clouded with a smoky hue. The predominating color is the violet of the ordinary alfalfa. The most conspicuous examples of hardy alfalfa are the commercial sand lucerne and the Grimm alfalfa of Minnesota. The sand lucerne has been grown for a number of years in this country. It has recently been found to be adapted to the colder and drier sections of the country, where it is proving the equal of any of the alfalfas under test. It seems particularly adapted to withstand the cold winters of the northern states, where ordinary alfalfa is very likely to winterkill. It is not always the heaviest yielder in sections where ordinary alfalfa succeeds, but its yields are always satisfactory, and it is espe- cially recommended for conditions where ordinary alfalfa does not succeed by reason of high altitudes, light rainfall, or severe winters. Its chief drawback is its tendency to lodge. The Grimm alfalfa, which has been grown for many years in Minnesota with excellent success, was brought from Wertheim, Province of Baden, Germany, in 1857, by a German farmer named Grimm. It is claimed by some that this variety has attained in- creased hardiness since its introduction into Minnesota. Dry-land alfalfa is the name usually given to ordinary alfalfa seed produced for one or more generations in the semi-arid sec- tions without irrigation. It is proving somewhat superior to ordi- nary alfalfa under semi-arid conditions, and as a drought- resistant alfalfa is about equal to Turkestan alfalfa and sand lucerne. Arabian alfalfa is proving of special value in the southwest- ern portion of the United States, where the winters are very mild. It is characterized by its large leaflets and the hairiness of the stems and leaves, quick recovery after cutting and very rapid growth during the growing season, and also by its ability to grow at cooler temperatures than ordinary alfalfa. On the other hand, it is extremely tender to actually freezing temperatures and generally winterkills in all except the southern and southwestern VARIETIES OP ALFALFA. 83 states. Its quick recovery after cutting and its longer growing season enable several more cuttings per season to be obtained than are possible for the ordinary alfalfa. Unfortunately, seed of this variety is not yet on the market. Peruvian alfalfa is similar to Arabian alfalfa, and is likewise characterized by its long growing season and lack of hardiness. It grows taller than Arabian alfalfa, but the stems are more woody. The seed is not yet on the market in this country, as it is not grown in Peru or elsewhere in large commercial quanti- ties. HABIT OF GROWTH. Alfalfa is a plant with marvelous root growth. It is not unusual to find alfalfa roots penetrating 6'. 8', or even 12' into the earth. Very much deeper roots than these are reported. It is even said that alfalfa roots have been found that were 30' or more in length, and doubtless this is true in favoring soils. Alfalfa is a desert plant by nature. All desert plants root deep and root far. By aid of these deep roots desert plants tide over long drouths; if there is no moisture in the top soil there is perhaps moisture lower down. Alfalfa is a wonderful for- ager for moisture and for plant food. It loves deep, permeable soils. Because its roots penetrate so deeply into the earth it does not thrive when the water table of the soil is too near the surface. Permanent water ought to be down at least 36" for alfalfa to thrive and if it is to last for many years even more depth is needed. Alfalfa Not a Grass. — Alfalfa is in no sense a grass. It has no communistic ideas whatever. Each alfalfa plant is a vigorous, hustling, independ- ent individual. It pushes. its roots down, sometimes in one large tap root, sometimes in two or three large roots. It fills the earth with its hairy feeding roots. It makes a branching crown of many stems. The deeper the roots can penetrate the larger the crown will be. The better the soil for alfalfa the fewer - (84) ALFALFA SIX WEEKS FROM SEED, SHOWING ROOT TUBERCLES. FROM LIFE BY EDNA HOPKINS. HABIT OF GROWTH. 85 plants will stand on the ground. One by one the weaker plants will be crowded out till at last the strongest plants will gain their normal position when there will be a plant for each square foot of surface in very deep, rich soils of the West, and these big plants with roots as large as one's ankle; or there will be four or more plants to the square foot, as in good land in Nebraska or Kansas; or there will be a plant for each 4", as, in thinner, poorer and shallower soils in Ohio and the East. Alfalfa roots will not stand close together in any al- falfa soil, be sure of that. Nevertheless it is good to start them thick, since spare alfalfa plants are better than weeds in the field. Roots. — Alfalfa roots are very tough, strong and hard to cut. Penetrating the soil so deeply they make drainage channels when they decay and thus make the soil more alive. They are hard to plow. Once cut off they do not sprout again, though the top part if kept in moist earth will send out new fibers and may grow. Alfalfa is not hard to destroy by plowing; once cut off and cultivated a few times it dies. The large roots are not the ones that feed. The small fibrous root hairs penetrate each tiny crevice of the earth and absorb the soil moisture and thus drink in their food. Going to great depths they are able to bring up mineral substances that may have leached down there. They are able to find moisture when the surface soil is parched with drouth. The Bacteria.— Alfalfa roots absorb all that is in 86 ALFALFA FARMING IN AMERICA. the soil in the way of nourishment, but what they find is not enough to satisfy the ambitions of the alfalfa plant. Therefore it calls to its aid a host of tiny slaves, the bacteria. All clovers have useful bacteria that live upon their roots and gather nitro- gen from the air. Then when the bacteria die the nitrogen is taken up by the plant and made into its tissue, into its leaves, stems and seeds. These bac- teria live primarily for themselves, fastening to the little root hairs. Soon these little root hairs push out tissue and enclose the bacteria in fleshy ex- crescences shaped like little grapes or seeds. These excrescences we call tubercles or nodules. They are as large as clover seed o and its store increased by each provident owner. No Ameri- can farmer should be content with his stores of fer- tility as they exist today. His fields are not rich enough if he can profitably make them richer, and CARBONATE OF LIME. Ill indeed with nine-tenths of the farms of America -the fertility is so low that any hope of profitable agri- culture thereon must first be based upon a stern and inflexible determination to build the soils and make them rich. It is a great thought then that we have here, that soils filled with carbonate of lime naturally grow rich of themselves if planted with leguminous crops, or even left in a state of nature, and that upon these soils stored abundantly with lime almost any degree of fertility may be built. And what other function has lime in the soil! We need not stop here to discuss its power to floculate and ren- der more porous the soil, its ability to bind together sands, and so on. Perhaps that power of lime has been exaggerated, but this is true, soils rich in car- bonate of lime are almost universally rich also in phosphorus. This arises from two causes, one that lime carbonates usually carry a percentage of phos- phorus in their own composition; the other, that they prevent the waste of phosphorus by its leach- ing away, or its uniting in insoluble compounds with iron or alumina. Lime the Basis. — To put it short, you cannot build a soil rich in either nitrogen phosphorus or prob- ably potash unless it is first rich in carbonate of lime. There is here a great field for thought. Hil- gard says that no great and enduring civilization has ever been built upon an acid soil. This seems true. Babylon stood on an alkaline plain rich in lime, Egypt's soils are reputed rich in lime, Greece was built upon marble hills, Borne upon limestone, 112 ALFALFA FARMING IN AMERICA. and the hills of Judea — where grew such grapes, such goodly grain, such grass that the land literally flowed with milk and honey ; Judea where David the shepherd boy walked and tended his sheep and grew to the stature of a man ; Judea, where Christ walked and lived and loved — is a land of limestone, the lime soft and honeycombed by water, constantly decaying and giving its riches to the -soil. It is a curious thought, indeed, that had it not been for the lime- stone in the hills of Judea, perhaps the Master of mankind might have been born in another land. Availability of Lime. — So far as the writer's re- searches have extended, everywhere that limestone is found alfalfa grows naturally, almost of itself. This book will be read by many men, we hope, who have not been blessed by being placed on soils rich in carbonate -of lime. Let them not thereby be overmuch cast down. This is an age of machinery and of cheap transportation. Limestone exists in incalculable amounts throughout a great part of the United States, and can be burned or ground raw, and transported from the cliffs to the farms at very small cost. This will be done some day, no doubt. It is only a question of the farmers awakening to the advantages to be derived from the use of abundant carbonate of lime, and their asking for it, when manufacturers will be glad in nearly every state, as they have in Ohio, to place the stuff on the market at a reasonable rate. My good friend, Prof. A. D. Selby, of the Ohio agricultural experiment station, himself almost 9$ great an enthusiast on lime as CARBONATE OF LIME. 113 writer, once remarked that " Never yet was found an abandoned farm in America that had in its soil anything like a sufficiency of carbonate of lime." Evidence of Lime. — It is easy to note the evidence of lime. Soils rich in it naturally cover with grass, which stops erosion, therefore the 'hills are smooth and rounded; roadsides are carpeted with grass as though seeded by some maker of lawns; animals stand tranquil and content in pastures filled with nu- tritious forage; horses grown on soils rich in lime have fine forms and much life and spirit; boys and girls have good teeth and strong bones; in fact nearly all agricultural joy centers around the abun- dance of carbonate of lime in the soil. Add Limestone. — If you have not enough lime in your soil get it. It is a thing fairly permanent in itself. The rain leaches it away, the soil acids dissolve it. We do not know yet just how fast these processes accomplish their object, yet it is not probably so very rapid. When you put a ton of limestone in your soil it lasts till it has been dis- solved by the rain or made inert by soil acids. If you put in enough lime your sons will have its bene- fits. With it you can set about soil building in good courage. With lime enough you can grow clovers, grow alfalfa, grow the best grasses. What fertility you add through stable manures will not leach away. A good German farmer in western Maryland re- marked one day as he spoke of the large amounts of lime they were burning to apply to their fields: "Yes, Mr. Wing, it may be true that lime is not 114 ALFALFA FARMING IN AMERICA. manure, but it certainly makes our barn manures last two or three years longer than they do when we do not use lime." The truth is that the presence in their soil of abundant carbonate of lime did two useful things — it stopped the leaching away of sol- uble nitrates and it promoted the development in their soil of the wonderful little organisms that can fix nitrogen in the soil, even without the aid of legumes, the azotobacter. Has any farmer failed to note that grass land, when full of carbonate of lime, gets stored full of nitrogen, even without the pres- ence of many clovers? That is the work, so scien- tists tell us, of these marvelous little azotobacter organisms. Carbonate of Lime Is Neutral. — There is an old saying that has done more to harm agriculture throughout the English speaking world than any other known combination of words. It is this : ' ' Lime enriches the father and impoverishes the son." This saying leads men to< believe that lime is a stimulant, something that enables plants to forage more vigorously and thus more quickly rob the soil, or else that the lime sets free plant food. There is, of course, some truth in these assumptions if applied to burned lime. Burned lime does attack humus or any vegetable or organic compound. Used in ex- cess it may render soils temporarily barren. But carbonate of lime never injures soil in any way. It is a neutral thing ; like sand it attacks nothing. Soil acids attack it; it welcomes the enemy and absorbs it into itself. Could we change that old saw to read, CARBONATE OF LIME. 115 * * Lime enriches the father, and the want of it impov- erishes the son," we would be near the truth. In England we read that while lime has been in use there for many centuries, it has largely been in neg- lect for the past forty years, and now there must be a decided awakening and'a renewed use of it or Eng- lish soils will relapse most sadly. Forms and Kinds of Lime. — Eaw limestone is a carbonate of lime. Burning it drives off the carbon and makes it a quick, or caustic, lime. After burn- ing, when it absorbs moisture and carbonic acid gas again and becomes air-slaked lime, it has then less causticity than when it was first burned. If it is slaked with a little water, so that it falls into a dry powder, it is caustic lime. If it is slaked and ground in a factory it is called hydrated or agricultural lime. It is sometimes ground without adding water, when it is termed ground lime ; or the raw limestone is ground into powder, which is called ground car- bonate of lime, or ground limestone, or raw lime- stone. Now, what of the virtues of these various forms of lime? The burning drives off nearly half the weight of the natural limestone; thus the resultant product is nearly twice as strong as it was before burning. Thus if it must be shipped a long way by rail it may save so much in freight that it will be better to use the burned lime. Burning has also made it biting or caustic. A lump of this caustic lime held in the hand and moistened will eat the flesh. Caustic lime 116 ALFALFA FARMING IN AMERICA. will attack vegetable matter or humus in the soil. Applied in excess it will destroy bacterial life, so caustic lime is not so safe to use as the raw rock ground, the true carbonate of lime. On the other hand one can use less of it and get effect sooner, be- cause of its energy. The difficulty in its use to pro- mote alfalfa growing is that one ought to use more than lime enough to correct acidity when he is lay- ing land down to alfalfa; he ought to correct the acidity and leave a goodly store of lime carbonate lying in the soil, so that alfalfa roots will be in actual contact as the plants grow. This one can hardly do with safety with caustic lime. Use of Caustic Lime. — How much caustic lime can be safely used and how can it best be applied ? Soils differ in their power to absorb lime safely. Strong clays and soils full of sour humus can take most; sandy, poor soils must be limed with care if caustic lime is used. There is some danger of ' ' lime burn," that is, of making soil temporarily barren by giving it an excess of caustic lime. The poorer the soils in humus the more danger of this. Yet I have seen alfalfa fields in Maryland where the only good alfalfa present was where the piles of lime had been slaked, and where probably the lime had been applied at the rate of ten tons to the acre or more. How much caustic lime can we use? No one knows just at present. I saw this experiment tried in Tennessee: On Idlehour Farm, near Knoxville, Tenn., James P. McDonald had tried to grow alfalfa on Tennessee Eiver lands. It 'had miserably failed. CARBONATE OF LIME. 117 Crab grass had choked out the feeble growth. Mr. McDonald was a stubborn man and had seen alfalfa grow in South America. He was determined to grow it on Idlehour. Suspecting that lime was the thing needed, he burned a lot of it on his own place and applied it with a manure spreader. His aim was to apply about two tons to the acre. In many parts he applied at least double that amount. Wherever the manure spreader dropped the lime the alfalfa grew luxuriantly and the crab grass, was vanquished. I could not but marvel as I drove through this wonderful alfalfa. It was the twenty- fourth day of July and the alfalfa stood above the axles of the carriage and was ready to be mown, the third crop for the season. There was hardly a bit of grass or any weeds in the alfalfa. To show that the lime had done the work, one could see where the man driving the spreader had left strips here and there without lime. In these strips was hardly any alfalfa, and it was little, feeble stuff, while just be- side it, where the lime had been applied, it stood up like a wall. Crab Grass and Lime. — It seems true that crab grass, that arch enemy of alfalfa in the south, is easily vanquished by use of a goodly amount of lime. I have enough evidence of this to believe that it may be laid down as a law that lime will cure crab grass in alfalfa. It is not probable that the lime destroys the crab grass, or is particularly injurious to it, but it so helps the alfalfa that it springs into quick growth and gets the start of the grass. Hardly 118 ALFALFA FARMING IN AMERICA. anything can stand before healthy alfalfa. Almost any weed will conquer unhealthy alfalfa. Lime is its tonic, its heal-all. Amount of Caustic Lime. — How much caustic lime will we dare use? In an acre of soil, counting the top foot, there are roughly about 2,000 'tons. The sweetening of this mass of soil cannot be accom- plished by any handful of lime. One ton to the acre is one part in 2,000; two tons to the acre is one- tenth of one per cent, of lime. It would seem folly to use less than two tons to the acre of caustic lime. Double that, well distributed, would almost cer- tainly do harm. Is there a man who has harmed his soil by putting in it four tons of caustic lime to the acre, seeing that it is well distributed, and that the land has good store of humus, and has then sown it to alfalfa? Caustic lime must not be supposed to remain caustic for a long time after it is applied to the soil. It soon absorbs carbon again and becomes a neutral and harmless substance. This being true, why not use some form of carbonate of lime in the begin- ning? The only answer is that it is sometimes cheaper, because of freights or lack of machinery for grinding, to use the burned lime. Other Forms of Lime. — Now for some other forms of lime. Air->slaked lime, as has been said, ha>s absorbed a lot of carbon and is not nearly so biting and caustic as the fresh burned lime. It is fre- quently for sale at a comparatively low price, be- cause it is a waste product about lime kilns. It is CARBONATE OP LIME. 119 safe to use in fairly large amounts on the land. Probably no harm would result from using as much as six tons to 'the acre of air slaked lime. One may burn his own lime and, putting it in piles, let it air slake on his own farm if he has time to wait, or he may buy it cheap from the refuse about the kilns. Bear in mind that it has gained in weight in slaking, and is only about two'- thirds as strong as the fresh burned lime. Ground lime is fresh-burned lime ground ready for use. It is very convenient to distribute, and there may possibly be some virtue in having it slake in direct connection with the land. The only objec- tion to its use is that manufacturers often charge pretty well for grinding it. The farmer can some- times grind it at home, or he can buy lump lime and slake it at home at almost no cost. He can pile the lime in little piles of a bushel in a place over the field and let it slake by absorbing moisture from the soil ; then when it is in powder spread it at once with the .shovel. Or he can slake it to powder in a large pile and apply it with a lime distributor or by use of the manure spreader. To first lay down in the manure spreader a thin layer of chaff or manure and set the machine on the slow speed, will make it work very well. Many manure spreaders are now made with special lime distributors. Time to Apply. — When is the right time to put on caustic lime! Not in direct connection with manure, since it will doubtless attack the manure and set free more or less nitrogen that may possibly be 120 ALFALFA FARMING IN AMERICA. wasted. Better to turn the manure under and apply the lime afterward. It can then be mixed through the soil with the disk or any sort of harrow. Lime sinks, rains dissolve it and leach it down, so usually it is best not to turn it down deep. It takes a liitle time for lime to neutralize soil acidity, so get it on some weeks or months ahead of the time that you wish to sow alfalfa. The time of year when it is applied is not essential. A farm is a busy place, if it is a business farm. So just get out the lime when- ever you have leisure, only remembering not to put caustic lime in contact with manure if you can well avoid it. Depth to Apply Lime. — As has been said, lime sinks, so it is usually best to put it near the surface. It ought, however, to be mixed as perfectly as possible with the soil, and is not very effective when left in lumps, since it is not then in contact with enough of the soil particles. There are soils that have such acid subsoils that they will not grow alfalfa more than a year or two before it perishes. In these soils the roots decay down about six inches below the surface. Sometimes this rotting is caused by too much water in the subsoil, but when the sub- soil is dry water will not stand in post holes, and then one must conclude that it is soil acidity that is a)t fault, especially if he finds by the litmus paper test that the soil is really sour. I have seen such soils along the Atlantic seaboard. In the making of these soils lime was left out and other combina- tions of chemicals put in that form probably mineral CARBONATE OF LIME. 121 acids. Liming the surface makes alfalfa start off vigorously and make good growth for a year or a little longer, then it begins to decay, and will rarely live the second winter. In these soils the need is to study how best to get lime down into the subsoil, or at least down in direct contact with it. I suggest that one way to accomplish this is to apply lime very liberally to the top of the land before plowing, then to turn the land as deep as possible, turning at the same time the furrows as near as practicable squarely upside down. A better plan, but more la- borious, would be to distribute the lime in the bot- tom of each furrow as the land was plowed, turning it under by the next following furrow. This puts the lime in direct contact with the subsoil. If a sub- soil plow could now follow and open the underlying ground, which would let some of the lime drop into it, the work would be done in an ideal manner. Value of Liming. — It may make men in California or Colorado smile to read of any such laborious way of making land ready for alfalfa in the East. They need not scorn the eastern man nor his soil or methods. He has in truth better opportunity to make profit from alfalfa growing than they with their splendid soils, rich in lime and phosphorus, and their fine, sunny skies. The eastern man has advantage of splendid markets. His alfalfa when he gets it is worth to him at least $15 per ton, and if he is a dairyman or a stockman buying wheat bran at $25 per ton he can very nearly replace a ton of purchased bran with a ton of alfalfa hay grown 122 ALFALFA FARMING IN AMERICA. near his own barn. Then eastern lands sell at com- paratively low prices; all along the Atlantic sea- board land can be bought for from $40 to $75 per acre that will, with proper preparation, grow from three to seven tons of alfalfa hay a year. Some western men are seeing this and coming back to the neglected Atlantic states, and with splendid west- ern faith and enthusiasm are building alfalfa soils there and reaping rich profits therefrom. I have in mind very many instances where liming lands has brought alfalfa after it had repeatedly failed before the lime was applied. Effects of Lime. — When God made soils He often made them by grinding up rock masses, either by use of glacial icebergs or by the grinding action of rivers. When these rock masses were of limestone, the result was a limestone soil filled with particles great and small of ground limestone or carbonate of lime. In some soils there are enormous amounts of this material. In some very fertile soils of northern Illinois, taking the top five feet there will be found in one acre as much as 500 tons of carbonate of lime. Such soils are always rich and productive. They are always natural alfalfa soils, provided they are well drained. Along most rivers the alluviums are pretty well stored with carbonate of lime, thus one sees the river bottoms growing alfalfa well when the near lying uplands are too sour to grow it at all. It is because of the greater amount of lime in these alluvial soils, that and the better drainage and fer- tility all around, that mark them as alfalfa lands. CARBONATE OF LIME. 123 There are river soils that -will not grow alfalfa, but they are soils made by the deposition of silt that came itself from land too poor in lime. Much of western Kentucky will not grow alfalfa without lim- ing, yet along the rivers, particularly along the Mis- sissippi Eiver, alfalfa grows gloriously. The same is true of the land across the -river in Missouri. Much Missouri land needs lime to promote alfalfa growth, but the alluvial soils near the Mississippi grow it beautifully, and alfalfa growing in southeast Missouri is assuming large proportions. In Kentucky the writer has observed certain steep, stony hillsides growing alfalfa luxuriantly, while many level and apparently much richer soils not far away would not grow it at all. The reason was plain ; the small stones were fragments of limestone, and the soil, though apparently poor, was yet rich in carbonate of lime, fairly well stored with phos- phorus and potas'h, and the alfalfa, finding itself so healthy and vigorous, foraged for its own nitrogen. In Washington state alfalfa grows splendidly along the eastern side and in the irrigated valleys of the middle section, because the soils there are alkaline and not sour, with abundant lime, but on the western slope of the mountains and along Puget Sound it grows hardly at all, because lime is deficient in those soils. On an island in Puget Sound the writer found very luxuriant alfalfa growing near the shore, and upon investigation found great quan- tities of shells buried in the soil. The Indians had 124 ALFALFA FARMING IN AMERICA. feasted on clams, it would seem, and this was the dumping ground for their shells during unnum- bered years. Here then was carbonate of lime, and it was most noticeable that the soil in the interstices between 'the shells was dark in color and evidently contained a good deal of humus, while the soil of the interior away from the lime was raw and yellow. The lesson is plain; in order to make alfalfa grow all over western Washington it is only necessary to apply lime, and as limestone is very scant in supply the best source, perhaps, would be these very shells, which could be ground to a powder and mixed with the soil. Lime in England. — In other lands men have long imitated Nature's way and used lime in large amounts. England is built upon chalk rock, arid chalk is a soft form of carbonate of lime. For cen- turies farmers have dug this soft chalk and hauled it to the fields, spreading it broadcast where it soon crumbled and mixed with the soil. The writer lias stood on the brinks of chalk pits in England so deep that only 'the tops of trees peeped above their edges and marveled as he reflected what enormous amounts of chalk had been taken from them and for what a very long time men had been doing good farming in that land. It is a curious thought, too, that the soil to which these good English farmers were applying this lime was already what we would term in America a limestone soil. It was a soil once derived from the chalk rock itself, decaying through the ages through the action of soil waters and soil CARBONATE OF LIME. 125 acids. Rains fall, they leach out lime, plants decay, turn sour, the acid attacks lime, thus year by year th top soil loses more and more its lime and tends to sourness. Once in Lincolnshire I walked down into a chalk pit where a laborer was loading a cart, on the farm of Henry Dudding, of Lincoln sheep and Short-horn cattle fame, and asked the laborer why he dug the chalk. "It be for the dung, sir," was the response. "And do you put it on the land?" "Ay, and it do make the clovers and the grass grow better, sir, ' ' was the response. This on a farm already buried in rich grass, already having enough lime in its soils so that sheep pasturing on them had bones like calves and cattle stood on legs like straight columns of a temple. Rider Haggard in his interesting book, "Bural England," makes frequent reference to lucerne, stating usually that it is grown where the land was chalky and drouthy. On one farm he found them applying a sort of marl that they dug from the sub- soil, this on the farm of Robert Stephenson of Bur- well, Cambridge. I quote : He described to me a process which I was not fortunate enough to witness, as in these days of depression it is, I under- stand, but seldom practiced on account of the initial expense, al- though it used to be common enough — that of treating fen lands with gault. This gault, a mixture of clay and marl, is dug from the subsoil out of trenches cut ten yards apart, and spread on the surrounding surface to the quantity of about 200 tons to the acre. The land thus treated is said to double its value. The cost of the operation may be put at from $15 to $25 per acre. One application will last from 10 to 12 years, the full benefits being experienced in the second year after treatment. 126 ALFALFA FARMING IN AMERICA. Mr. Stephenson also grew lucerne, and when he wished to sow down land to grass for a permanent pasture, sowed the grass seed in the lucerne field, finding that the seed took well there (as we have all learned, of times to our sorrow), and that the lucerne or alfalfa furnished good pasturage till the other seeds came on. I have mentioned these foreign uses of carbonate of lime because agriculture is so recent in America that we have not much precedent to which to refer, and agricultural practice abroad is the result of experiences of the fathers for centuries back . What- ever one finds them doing over there he may feel pretty certain has been well tried and tested. In Scotland I have seen heath land reclaimed and made into farming land. The process there was to first drain the wet, sour slopes, then lime them with about thirty tons to the acre of lime, the raw carbonate of lime being used, if I remember correctly, and after that manure was used; then clovers, turnips, oats, grass or any good thing that the climate would grow. New Work. — It is rather a new work, this use of carbonate of lime or raw ground limestone in Amer- ica. A few years ago nothing could be done except to dig marls out of the earth where they were to be found, and as these marls were nearly always under water not much of this has been done. With the increase in use of concrete construction came call for crushed limestone. Railways asked also for crushed limestone for ballast material. Crush- CARBONATE OF LIME. 127 ers of great size and power were installed at lime- stone quarries and quantities of limestone dust ac- cumulated. Finally men began hesitatingly to use this limestone dust. The results were astonishingly good. Then quarrymen began advertising the ground limestone and selling it at a low price. The farmers took hold of it in Ohio, Illinois and some other states, and at last quarrymen began installing large crushers and grinders that took the raw rock from the quarry and reduced it to powder, making the whole output fit for farm use. This is usually put on cars in bulk and sold for from 75 cents to $1.50 per ton. The low price quoted is from a point in Illinois where the writer believes the state, with convict labor, grinds limestone for agricultural purposes. Limestone Harmless. — This ground limestone is harmless to the soil, so one may use as much of it as he chooses. Dr. Cyril G. Hopkins of the Illinois experiment station has applied it at the rate of 100 tons to the acre with not the least sign of injury to the soil. It is pleasant stuff to work with, not acrid and biting like burned lime if it gets on your skin, nor does it get caked together if it happens to get wet. One may put it on his soil at any time that suits his convenience. He may put it on in connec- tion with manure if he wishes and no harm will result. It cannot burn out the humus, it attacks nothing. Soil acids attack the particles of limestone and are neutralized, but the lime itself does no harm no matter how much is used. It is nature's way of 128 ALFALFA FARMING IN AMERICA. using lime in the soil. Some day, soon let us hope, there will be thousands of machines busily at work grinding up the raw limestone rocks, which fortu- nately are plentiful enough in America, and farmers will be busy spreading this sweetening powder broadcast over their land. Distributing Lime. — I have found some difficulty in distributing limes. Spreaders there are, but usually they do not apply it nearly fast enough. There will be machines devised that will apply as much as one wishes, up to ten tons to the acre, no doubt. At present the manure spreader seems as satisfactory as anything available for spreading ground limestone. Quantity of Lime. — How much should be used on an acre? It is difficult to say. The art of lim- ing is too new in America, especially with carbonate of lime, ground limestone, to give us much data, We can only guess. The writer has known of remark- able results from use of as little as three tons per acre of ground limestone. This seems an infinitesi- mal amount when one considers the 2,000 tons of soil in the top foot of an acre. Take that acre apart, there are 160 square rods in it. Supposing one were asked to lime one square rod sufficiently to sweeten it well, using the inert ground limestone, how much would he naturally put in? Most sensible men would put in at least 500 pounds, supposing cost was not considered. That would make forty tons to the acre, and we cannot afford tha.t now; there are too many acres to be limed. But we can afford 100 CARBONATE OF LIME. 129 pounds to the square rod, and that seems little enough, and yet it means eight tons to the acre. That amount I would advise when the material can be had cheap enough to make it possible, and even more. It costs! Yes, but it pays. Take an acre of old, sour land that is not worth cultivating in its natural state and put on it eight tons of ground limestone. Put the cost at $2.50 per ton. That means an expense for liming of $20 per acre. Then that land will be fit to sow alfalfa upon, as soon as it has been drained and enriched. Mind, we do not claim that lime is a manure. The lime makes it possible to grow crops that make manure. With alfalfa growing well upon that acre it ought to yield at least four tons each year, and there is a thousand pounds of hay for each ton of raw limestone rock you have used. Cannot afford it? Can you afford not to do it? But with much less ground limestone on some soils alfalfa has come where it had failed repeatedly before. Among a mass of similar letters I find this significant one from Iowa : "After repeated failures with alfalfa in this county (Scott, Iowa), I have acted on your advice and applied 3,000 pounds of raw limestone dust with the seeding in August of 1907. This acre, diagonally across the three different varieties, produced a uni- form luxuriant growth of alfalfa at the three cuttings, besides a growth of one foot not cut. I estimate each cutting at two tons per acre. The rest of the field showed a patchy growth ranging from two inches to 18", very unsatisfactory. I am convinced that you are right when you say that raw limestone will assure suc- cess with alfalfa." I tried for several years to help a farmer in east- ern Pennsylvania grow alfalfa, but each effort was 130 ALFALFA FARMING IN AMERICA. without success. I advised drainage, and the land was drained, but yet alfalfa refused to grow. I advised manure, and the land was made so rich that hog weeds grew as high as a man's head, and yet alfalfa refused to grow. I advised much phos- phorus with no result. Different times of seeding were tried, and inoculation of the soil, and yet only failure resulted. Then I gave much belated advice to lime, and lime well, to use eight tons of ground limestone to the acre and seed in late July. The man did nearly as he was told, putting on six tons of raw lime dust to the acre, and the very next year cut six tons to the acre of alfalfa hay. His field was the marvel of all the country around, and men came to see it. I could multiply these instances almost indefi- nitely. Lime in Soils. — The reader should bear steadily in mind that the natural alfalfa growing regions of the world have in their soils now about from .5 per cent to 4 per cent of carbonate of lime. Five-tenths per cent is half of 1 per cent, or about ten tons of car- bonate of lime to the acre. Four per cent, would be approximately eighty tons of carbonate of lime to the acre. These figures are for the top foot of soil only. In natural alfalfa soils the subsoil is usually richer in lime than the top soil. When a man lives away from the limestone it is his privilege to buy carbonate of lime and add it to his soil. And when he lives in a region where limestone rocks abound and the soil is yet deficient because of leaching1 rains CARBONATE OF LIME. 131 of many centuries, it is his privilege to crush and grind the rocks of his own farm and put the dust over his land. Farm Machines for Crushing. — In this connection it may be remarked that there are now machines made that will take the raw rocks that may crop out on a man's own farm and grind them into usable dust, the machines being mounted on wheels and readily portable, so that they can be drawn from one farm to another, as need demands. Thus the farmer may have a machine come to his own farm and grind up for him a pile of limestone of as many hun- dred tons as he desires. It will lie in pile unharmed by weather till he is ready to put in a field. There are many thousands of acres of land in Ohio, Tennessee, Kentucky and adjoining states that is fairly fertile, is naturally pretty well drained so that the expense of drainage will be but slight, and that only awaits the coming of lime carbonate to make it produce good alfalfa. And the beauty of it is that in Tennessee and Kentucky very often the limestone is right in the neighborhood, and some- times right on the farm where it is needed. Summary. — I realize that I have taken not a little time to present this matter. My apology is that the subject is fraught with such import. The wealth of our land can easily be doubled. Drainage is the first step. Use of carbonate of lime is the second step, and the third is the addition of humus to the soil, the use of phosphorus, in some instances of potash, and the sowing of alfalfa. Or, if there is 132 ALFALFA FARMING IN AMERICA. prejudice against alfalfa, then sow clover, or any other useful legume. Sure it is that once the land is dry and sweet all the other good things will nat- urally follow in train. Bacterial life in the soil, sweet and abundant crops will follow with better animal life, more hope in the farmer's breast, better schools and more children in them, better country roads (for there will be money to pay for them) and a higher level of life and living all around. Fertility and Abandoned Farms. — Prof. A. D. Selby of the Ohio agricultural experiment station, in an essay read before the Columbus Horticultural Society in 1907, on the question of "Abandoned Farms," makes the following significant remarks concerning the intimate relation between soil sweet- ness, soil bacteria and soil life, and the continuance and progress of farm occupancy. We quote: Vietch has made the following observations: "Broadly speak- ing, no more striking proof of the importance of maintaining an alkaline reaction basic condition of the soil is needed than is furnished by those soils which have become famous for their persistent fertility under exhaustive cultivation. The loess soil regur of India, Tschernoseum of Russia, chalk of England, basalt of the far northwest, prairie of the middle west, blue grass of Kentucky and Tennessee, and the limestone valleys of the east are soils which are recognized as the most fertile in their respective localities, and have maintained their pre-emi- nence in fertility, in some cases for thousands of years. These soils are all basic in character, alkaline in reaction. The history of liming furnishes more general evidence upon the value of an alkaline reaction of the soil as one of the chief economic factors in crop production. * * * I believe it was Berthollet who observed that "la terre est quelque chose vivant" — "the soil is a living thing." In a much greater degree in our day than in Berthollet's day we recognize the soil as a living medium, whose biological content is now rich or now poor, here abundant and full of vigorous possibilities CARBONATE OF LIME. 133 or there marked by a paucity in both organisms and cultural possibilities. In whatever sense my hearers may conceive of the earth, whether here covered by a wide range of growing species of trees, shrubs, herbs and grasses, and there bedecked within the range of a single farm with a number of fields in different crops, say of potatoes, corn, oats, wheat, clover, hay and the like, in like degree do I ask them to conceive of the vastly richer co- incident microscopic life present within these highly cultivated soils working ceaselessly and ever and anon multiplying in incalculable numbers, yet ever, so long as favorable cultural conditions are possible, maintaining themselves both as to the variety and number of sorts. Granting once this conception of the soil, we can understand that it is an enclosing nidus as well as a nutrient medium which supports this life within and upon it. This nidus may be here rendered highly acid in reaction by the decomposition of vegeta- ble tissues that are incorporated in it or there become excessively alkaline if no soil leaching may occur, as with certain alkali soils of the west. But conceive in this same connection the great difference as a result of years of culture that will come about in a soil deficient in available bases which may at all times be relied upon to correct automatically the acids produced by the fermentations and decompositions taking place in the soil, as compared with a soil at the outset very largely composed of in- soluble silica or sand, and lacking in these same automatic cor- rections of cultural tendencies. I would here again insist that these abandoned farms as farm lands are abandoned, because they come soon to lack that biologic balance in these nidus rela- tions and in their contained organic life as well. May we not add that the practice of rotative farming, of which this region shows an advanced type, has its justification and its profit in the very biologic balance maintained thereby? May we not go even further and point to continuous cropping in a single species as an extreme disturbance of this balance of soil organisms at the same time that it uses up particular soil con- stituents? I am convinced that in both cases we may reply in the affirmative and that fuller knowledge of soil life may show most strikingly the mistake of continuous cropping just as the breeding and introduction of so many soil diseases of the special crop have so often shown its economic disaster. What has just been stated with some fullness is not given as a proven thesis; rather as a suggestion that has for many years been driven step by step into the writer's soil conceptions in the course of somewhat extended observation and reading upon farm 134 ALFALFA FARMING IN AMERICA. and soil subjects. No pretensions are made to special qualifica- tions in this line, but none the less the writer is firmly convinced that more than soil chemistry, as it has been applied for a century, and more than soil physics, as so ably enlarged within two decades, is needed to furnish the explanation of the vital changes of the soil and their relation to successful agriculture. When the line between calcareous or limestone outcrop and sandstone outcrop marks as it does the line between profitable land and unprofitable land for certain crop purposes, as it seems to do in some portions of Ohio, it may not be wholly heretical to look to the calcareous compounds as offering at least a part of the explanation of the differences. When history adds the weight of evidence in the maintained fertility of particular calcareous soils the same question is again raised. And since the soil chem- ist and soil physicist have not marked out the differences either in kind or degree, an appeal to the soil biologist, to the soil bacteriologist should now be made. Chester of the Delaware sec- tion once made determinations of the number of bacteria in a gram of a certain Delaware soil before and at periods of a few weeks after this soil had been treated to dressings of lime of various amounts and to Thomas slag. These were all in pots in comparison with untreated soil from the same source. The acidity of the original soil was determined and the amount of correction afforded by the treatment was also determined by the same method; while the untreated soil maintained an almost uniform bacterial floral of about 520,000 bacteria per gram of soil, the soil treated to dressings of lime showeu only a partial correction of apparent acidity, but an enormous increase in the number of bacteria per gram of soil. With smaller amounts of lime, say at the rate of 1,000 pounds per acre, the number of bacteria reached 2 to 3,000,000 per gram while with 4,000 pounds of lime dressing per acre, the number of bacteria reach 5 to 8,000,000 per gram of soil. If nothing more may be said, we cer- tainly conclude that these results are very suggestive. I wonder if we have really begun the study of the problem of applying lime to siliceous soils? Basic Slag a Source of Lime. — There is a phos- phatic fertilizer on the market in eastern states wherever convenient to ocean ports that combines very nicely available phosphorus and lime. That is the Thomas phosphate or basic slag meal. This stuff is a by-product of the steel mills of England CARBONATE OF LIME. 135 and Germany. Our own iron ores, being poorer in phosphorus, do not make much of this substance. It is in great use in the Old World. Germany alone uses 2,000,000 tons of it each year. Wherever tested in America it seems to give very satisfactory re- sults. The writer tested it on Woodland Farm many years ago and never got stronger, healthier alfalfa than by its use. Basic slag usually contains from 16 to 20 per cent, of phosphoric acid with from 36 to 50 per cent, of lime. It is said that the phosphoric acid is in a form that is nearly all available, and it can- not revert in the soil nor leach away. There is hardly a farm east of the Missouri river where more phosphorus will not yield profit. Where freights are not too high, basic slag costs no more for the available phosphoric acid than any other source of phosphorus, and thus the lime is gotten free. It is advised that from 1,200 to 1,500 pounds per acre of basic slag be applied where alfalfa is sown. The large surplus of phosphorus thus given will not leach away, but will remain to feed the plants for some years, while the lime will help sweeten the soil. Basic slag costs too much for use at present in the cornbelt states. Where it is available is in New England, New York, and along the Atlantic sea- board. The price is about one dollar per unit of phosphoric acid ; that is, slag analyzing 17 per cent, available phosphoric acid would cost the consumer about $17 per ton. At present writing the Coe- 136 ALFALFA FARMING IN AMERICA. Mortimer Co. of New York import most of the Thomas phosphate. I have seen astonishing results from the use of this substance in England, where it is applied to meadows and pastures. In May in England one sees many manure distributers or fertilizer distributers going over the meadows and pastures. If he will take trouble to see What these machines are distrib- uting he will find in most instances it is basic slag that is being sown over the grass, sometimes with an addition of nitrate of soda or potash. Where the basic slag is put, very marked result is seen in the clovers that spring up in the grass. Even when no clover seeds are sown at all the result is often as though it had been sown to clovers, since a rich growth of them comes up and overtops the grass. The explanation is that the clovers or their seeds were already in the soil waiting for favorable conditions. The coming of the phosphorus fed the little plants, then the lime sweetened in a degree the soil, and the plants shot up and overtopped the grass. Thus the forage was much enriched, and later when the clover leaves and roots decayed the soil was so enriched that the grass was greatly thickened and strength- ened. When one is applying annual fertilization to his alfalfa meadows he may well consider the use of basic slag. Sour Soils. — It may be asked, "How do soils be- come sour?" Any vegetable matter decaying in the soil will create an acid there. From sweetest apples is made the sourest vinegar. Tea leaves put in a CARBONATE OF LIME. 137 stone jug with water will make a sour vinegar, as the writer tested in his ranching days. Soil acids accu- mulate in soils that have no lime to neutralize them. Some plants grow well in sour soils, but not many useful plants. Wild things grow most in acid soils. Useful legumes grow poorly, if at all, with some ex- ceptions. And alfalfa refuses to grow at all with the soil sour. How is one to judge if his soil is sour? If he is experienced in soils he can tell by the character of plant growth on the land whether it is sweet or sour. Certain grasses betoken sour lands. Sorrel, or sheep sorrel (Kumex acetosellan) is pretty sure to come where there is lime deficiency, and sorrel and alfalfa do not go well together. There is a simple test that any one can make with litmus paper. This is a blue paper that can be bought of the druggist, usually in little slips, stoppered in glass bottles. One can take a slip of this paper and some of the suspected soil, having it moist, and insert half the length of the slip in the moist soil and let it remain in contact for half an hour. If there is any apparent redness in the paper be sure that there is acidity in that land. If the blue paper does not turn red the land is at least neutral. To test whether the land is actually alkaline with lime, which it ought to be to grow big alfalfa, expose a slip of the paper in quite weak vinegar only long enough to turn it red, then insert it in the soil and leave it for an hour, having the soil moist and in contact. If it then turns blue again you may be sure that you can grow it on that land, 138 ALFALFA FARMING IN AMERICA. This then is true: to get maximum crops of alfalfa, to grow it as though you were growing a weed, make your land alkaline with lime, instead of having it acid. Then get it dry, add proper amounts of fertility, and the only troubles you will have will be in caring for the crops of hay and some day in breaking your tough alfalfa sod. Where the Lime Soils Lie. — Where probably are soils already filled sufficiently with lime, and where are 'they deficient from the standpoint of the alfalfa plant? In no part of the arid and semi-arid region has there been found evidence of any need of lime in the soil. Often there will be found from !T/^% to 4% of carbonate of lime in those soils. This would be equivalent to from 30 to 80 tons of this substance in the top foot of soil of each acre. Coming eastward it is doubtful if any part of Nebraska, Kansas or the Dakotas need lime, except in their eastern portions or in especially sandy parts. It seems certain that the western portions of these states have lime enough already. Southeastern Kan- sas needs lime, so doubtless do parts of Oklahoma and the Indian Territory. Texas has a great diversity of soils. Parts of Texas are tremendously supplied with carbonate of lime. There alfalfa is almost a weed, suffering only from lack of sufficient rainfall. Eastern Texas, on the other hand, needs lime very badly indeed to make alfalfa thrive. Along rivers the alluvial soils are usually well stored with lime. CARBONATE OF LIME. 139 Arkansas needs lime badly, except in her alluvial soils along the Mississippi Kiver. There one sees luxuriant alfalfa grown. Some of the "buckshot" soils of Arkansas have in them a great amount of lime carbonate and are destined to be great alfalfa- producing regions. The hill soils and uplands mostly are in need of more lime. There are excep- tional areas of upland that have already sufficient lime native in their soils, but these areas have not yet been accurately defined. Missouri grows alfalfa about in proportion to her lime content. In Pemiscot county along the Missis- sippi River on "buckshot" soil alfalfa grows glori- ously. This soil contains about 1*4% °f calcium carbonate. Prof. M. F. Miller, of the Missouri Col- lege of Agriculture, reports that where about y* of 1% of carbonate of lime is in Missouri soils and humus is supplied through use of manures, alfalfa thrives. At this time (1909) it is unknown how much of Iowa would be helped by application of more lime. A letter giving results from Scott County is pre- sented on a preceding page. It is probable that over much of the prairie section of the state a light application, say one ton to three tons per acre of ground limestone, would put the right condition there for proper bacterial life in the soil. That is about all there is to it; lime enough is needed to make the earth swarm with the right sort of bac- teria. Lime enough is needed to correct any toxic principle exhaled from the alfalfa roots, 140 ALFALFA FARMING IN AMERICA. All the region east of the Mississippi River will be helped by use of ground limestone, with the ex- ception of some favored spots where glaciers have already ground the rocks to powder and mixed it through the land. Anywhere that alfalfa fails to thrive after the land has been made dry and fairly rich one may know that carbonate of lime is de- ficient. Especially may one be sure that all soils along the Atlantic seaboard are deficient in car- bonate of lime, and by supplying this lack their capacity for crop production may be immensely increased. The Chemistry of Lime. — In "The Breeder's Ga- zette" of July 14, 1909, Dr. Cyril G. Hopkins, agron- omist of the College of Agriculture, University of Illinois, sets forth clearly the chemistry of lime in its relation to soil improvement. I quote his state- ment complete : The use of lime for soil improvement is a subject which is dis- cussed with a great deal of misconception and confusion, due in large part to the erroneous practice of referring to lime as though it were a chemical element. Lime is not an element and consequently is not an element of plant food. It is an alkaline substance and is known in three forms: the carbonate, the oxide and the hydroxide. The carbonate is the natural form found in rocks and soils and it consists of either calcium carbonate, magnesium carbonate or a double com- pound of calcium magnesium carbonate known as magnesian limestone or dolomite. When highly heated these carbonates lose their carbon dioxide as a volatile gas and the oxide or quicklime remains. This substance takes up water either from direct appli- cation or from the moisture of the atmosphere and changes into the form of hydroxide or water-slaked lime. On long exposure to the air the hydroxide will absorb carbon dioxide from the air and give off water, thus reforming the carbonate compound. Thus, we may say that calgiunj earboaats (CaC03), calcium oxide (CaO) CARBONATE OF LIME. 141 and calcium hydroxide (Ca02H2) are ordinary forms of lime; also that magnesium carbonate (MgCO3), magnesium oxide (MgO) and magnesium hydroxide (MgO.HJ are the correspond- ing magnesium compounds, more or less of which are contained in magnesian limes, of which the most common form is calcium magnesium carbonate CaMg(C03)2. Any of these compounds may be used for neutralizing acids and thus for correcting the acidity of the soil. If it can be kept clearly in mind that these are the substances properly called lime, and that nothing else is lime, much confu- sion can be avoided. However, a compound properly named cal- cium chloride (CaCL) is often called chloride of lime and yet it contains no lime whatever and does not possess the property of lime. In other words, it is not an alkaline substance and has no power to correct the acidity of the soil. It does contain the ele- ment calcium which is also contained in the ordinary forms of lime, but the element calcium is not lime. Now let us turn to the subject of plant food. There are 10 essential elements of plant food and it is true that calcium is one of these elements and that it is required to a greater or less ex- tent by all agricultural plants, but it is not at all essential that calcium as an element of plant food be applied to the soil in any form of lime. It may be applied as calcium sulphate or as calcium phosphate, and it even exists in many soils which are absolutely devoid of lime which are even strongly acid and markedly in need of lime, but which, nevertheless, may contain abundance of cal- cium for plant food in the form of acid calcium silicates. Thus the acid soils of Illinois which require an application of several tons of ground limestone to correct their acidity contain several tons of the element calcium in the plowed soil of an acre. In some cases soils are found which are not only deficient in lime but also deficient in the element calcium and on such soils the application of any of the calcium limes would furnish both lime for correcting soil acidity and the element calcium for plant food. Summary.— Alfalfa is one of the most beautiful, most valuable and most profitable crops in the world. It makes the most hay. The hay is the rich- est and best. It enriches the soil on which it grows. It endures for many years with one sowing. It has redeemed the arid and semi-arid west, It is coming into every state in the Union. 142 ALFALFA FARMING IN AMERICA. Many needless failures in attempts to grow alfalfa have resulted in eastern states. Alfalfa need not be a hard plant to establish. It is hardier than red clover. It withstands any drouth. It withstands cold better than any other clover. In some regions alfalfa seems native to the soil. In other regions all the nursing in the world fails to establish it. Why is this difference? All natural alfalfa countries have the soil filled with carbonate of lime. There may also be other alkalies in it, and sometimes injurious alkalies, but carbonate of lime is the useful thing found. Wherever the soil is well stored with carbonate of lime alfalfa grows like a weed, if other conditions are good. Where the soil is acid no amount of manure will keep alfalfa alive very long. Carbonate of lime is the sort that God put in the soil when He made it. Burned lime is man's at- tempt at improvement. Burned lime may help and may harm. Carbonate of lime, that is, raw ground limestone, never harms soil. It cannot harm soil, use it as freely as you like. One could put on 50 tons to the acre and do the soil no injury. It would merely lie in the soil inert till it was required. Car- bonate of lime is needed to make the bacteria of alfalfa thrive. It is needed to free the soil from poisons that destroy both bacteria and alfalfa. Car- bonate of lime stops waste of fertility, makes vege- table matter into humus, arrests fleeing nitrogen. Ground limestone will make alfalfa grow without fail, if a £§w other easily met conditions are com- CARBONATE OP LIME. 143 plied with. The amount needed will vary; all soils have already some lime in them. Where there is marked deficiency apply 100 pounds of ground lime- stone to the square rod for alfalfa growing. Always leave a strip unlimed to note the result. Here are the few simple rules needed to assure alfalfa : First, water let out of the soil and air let in by drains. Second, soil made alkaline, not neutral, with ground limestone. Third, soil with some humus in it, preferably from stable manure. Fourth, soil with phosphorus and a little potash, the phosphorus preferably from bone meal or basic slag, though acid phosphate will answer. And use enough of it. Alfalfa feeds heavily on phosphorus. Fifth, good seed mixed with some soil from a good alfalfa field or from a sweet clover patch, sown on a deeply plowed, firm, fine seed bed, any time between April and September. Ground limestone insures vigorous alfalfa. Vig- orous alfalfa is the most energetic soil enricher in the world. When it has stood a few years if it is then plowed and planted to corn the result is simply marvelous. A field well set in productive alfalfa will yield 5 tons to the acre. This is easily worth $10 to $15 per ton, as alfalfa hay is nearly of the same value as a feed as wheat bran. Thus you note that it yields good interest on a valuation of $250 per acre, 144 ALFALFA FARMING IN AMERICA. Common farm lands do not pay well. Invest in limestone, manure, phosphorus, alfalfa seed, make over that $75 land into $250 land and farming will pay you. Visiting a Stone Quarry. — A visit to a limestone quarry is an interesting thing. These thoughts came one day to the writer as he strolled with a company of Ohio State University agricultural stu- dents beside the quarries at Columbus, Ohio. A great mass of limestone rock rises to within a few feet of the surface of the soil. Here the Scioto river, cutting its way through, has eroded a chan- nel, exposing cliffs of limestone; here have come quarrymen seeking to mine the rock for building, for road ballast and for grinding to put upon the soil. Upon this scene burst a class of students, eager and curious to note everything, like happy children out of school, climbing over the heaps of debris, shouting merry jests and making exclamations of surprise as they note the many curious revelations. Here, by the railroad embankment, newly made, spring up blue grass and white clovers, their roots in the crumbling limestone of the ballast, eloquently telling how waste soils may be restored and covered over with vegetation where lime is. To our left a tangled jungle of old dry weed stalks standing upon heaps of limestone debris, and as we plunge within this jungle we find the weeds are mostly sweet clover, growing huge and lusty, laden last summer with flower and yet bearing seeds. Think of the CARBONATE OF LIME. 145 myriads of bacteria on the roots of this sweet clover, busily soil building, getting this waste land ready for more useful things. Now we stand at the brink of the quarry, a great hole in the ground. Our gray haired teacher asks us if we know what is the most durable of all man's work upon earth, and smilingly he tells us that the most permanent thing that man has ever yet achieved is a hole in the ground. But, think of the human energy required to quarry and cart away these millions of tons of limestone that once filled this excavation ; and think further than that, to the time when this part of the earth was a shallow sea where warm waves rocked endlessly and little shell- fish swam and crawled, and dying one by one, be- queathed their bones to make the limestone that was one day to become this rock; and next, the quarry- men, short, thick, brown men, hugely muscled, pounding away upon the rocks as though they loved it. They too tell the story of lime, for is not the island of Sicily one limestone rock? Yes, and these sturdy peasants tell another story, the story of the vigor that may come from simple living. For cen- turies their food has been macaroni and olive oil, with, let us hope, an orange for dessert, and yet to- day they can in physical energy far surpass the meat-eating American. And what are they doing, these swarthy Italians, with dynamite mightily shat- tering this rock, 'with steam locomotives dragging it to the crushers, and there dumping it into yawning jaws that mightily bite and chew it until it is shaped 146 ALFALFA FARMING IN AMERICA. for railway ballast or for concrete construction? And here is another machine, more interesting yet, a machine of prophecy, a machine meaning great things to the farmer, for in this machine, so small and apparently insignificant, the rock is ground rapidly into powder and this powder through end- less carriers is loaded into cars, no man's hands touching it after it is first dumped, and from this mi]l it goes forth by cars to the fields of Ohio. Think what this means; somewhere an old sour clay field refusing to grow clover, refusing to grow anything rich enough to yield profit, sending no boys to col- lege, giving little hope to the owner, and now under one shower of this ground limestone will come the miracle. The sourness will disappear, clover will grow, the bees will hum, the mower will click, the boy will whistle, books will come into the home and magazines, and let us hope some lad from that farm will start to the university. Building Soils to Stay Built. — My father was a firm believer in the idea that a soil could be so en- riched that it would afterward stay rich, that it would gain momentum enough, so to speak, so it would keep on caring for itself afterward. There- fore he would apply manure in large amounts to one spot of land after another, seeking to establish this condition of things. There is much basic truth in his theory and his practice was not far wrong. When much manure is worked into sweet soil, a soil well stored with car- bonate of lime, there is set up there a laboratory CARBONATE OF LIME. 147 where fertility is steadily manufactured. There will be air in such a soil and bacteria in enormous abundance, among them the useful bacteria that live upon any sort of decaying humus in the soil and gather nitrogen from the air, the new-found azobac- ter. Thus there is a perpetual fertility-gathering plant established right in the soil. It all depends, after all, on the possession by the soil of a large amount of carbonate of lime. If that is absent the fertility put there in excess of the needs of the plants soon leaches away and is gone. The writer has traveled in lands very deficient in lime, so deficient that the well water was almost as pure as distilled water, and there has noted that not only were the fields incredibly poor, but even such places as barn lots had in them very little richness indeed, though manure had been wasted therein for a century or more. Think how old the world is ! And since the rocks cooled and vegetation started to cover the earth roots have been decaying in the soil and leaves fall- ing thereon with stems and branches and all man- ner of debris. Enough vegetable matter, enough humus-forming material, has fallen to the earth and become buried in the earth nearly everywhere, to make the soil incredibly rich. Instead we commonly find even wild soils rather poor. Why? Because of the lack of carbonate of lime. That is the one thing that can fix fertility and hold it for use in future years. On the old farm at Arlington, near Washington, it 148 ALFALFA FARMING IN AMERICA. is said that manure enough has been applied since it has been in possession of the United States to cover the soil with a layer several feet deep, and yet the land is of only very moderate fertility. Why f Because it is so lacking in carbonate of lime. Coming back to my father's idea that land could be given such an impetus towards fertility and pro- ductiveness that it would "keep a-going " it should be said that it is only a partial truth, after all. Doubtless the nitrogen content of the soil can be maintained. In order to do this leguminous crops should come with somewhat frequent recurrence, since legumes restore nitrogen faster than anything else we know. And alfalfa is the most vigorous ni- trogen gatherer at our command. No one can store a soil with fertility and draw upon it with maize or oats or wheat or timothy grass without rapidly depleting his store. All these things are s'oil rob- bers; they do not create or secrete fertility for the soil. Phosphorus Needed. — Nor can legumes or alfalfa do impossibilities. The mineral elements are pres- ent in fixed amounts. Of potash one may have a great abundance and on many soils need never worry nor concern himself, but phosphorus is usual- ly a thing needed and not in sufficient supply. It must be remembered that plants cannot build their tissues, form their blooms and mature their seeds without using in regular "balanced ration " all the elements of plant food. They cannot make use of an excess of nitrogen profitably when phosphorus is in scant CARBONATE OF LIME. 149 supply. Thus on Woodland Farm, which is rapidly becoming fertile — nearly as fertile, probably, as it is profitable to make farm land — we find it wise each year to purchase this one element, phosphorus. We put it. on when we start alfalfa. We put it on the old alfalfa meadows. It pays largely in increased yield and in increased vigor of the plants. This makes the alfalfa able to resist weeds and rust and all the enemies of it. And once on the farm much of the phosphorus is retained, is used over and over again. When we cut the hay we take up phosphorus, and if we were to sell the hay this would be drained away and lost, but when we feed the hay on the farm, as we try to do with most of our crop, we sell away only as much phosphorus as is contained in the wool and mutton of the lambs and in their bones, and what goes to the manure is pretty care- fully saved and put back on the land. Thus our store increases steadily. MANURES AND HUMUS IN SOIL. I have dwelt so long on the subject of carbonate of lime that I must now take occasion to emphasize that lime is not sufficient plant food. Lime promotes bacterial life and saves plant food and makes it available and helps it accumulate. After one has his soil well filled with carbonate of lime, then he is ready to begin to build it. If nature had filled that soil with carbonate of lime ages ago she would have gone on with the work and stored it with vegetable matter, humus. Then there would be now in that soil nitrogen and bacteria in abundance, and prob- ably abundant phosphorus and potash as well, since phosphorus is nearly always in pretty good supply where carbonate of lime is plentiful in the soil. Let us get clearly in mind here that liming is only a step in the soil-building process; it is the founda- tion of things, as it were. And now again let us re- peat that soils are living things. The productive- ness of the soil is dependent, upon the numbers of bacteria found therein. Bacterial life is not abun- dant in soils that are deficient in humus, vegetable matter. Stable Manure Best Source. — The very best source of humus is stable manure. If the reader has fol- !owed the story of Woodland Farm, related in the be- ginning of this book, he will have in mind the great part that manure played in building the alfalfa (150) MANURES AND HUMUS IN SOIL. 151 fields. Early in our experience we learned that wherever we applied a good coat of manure, there we got luxuriant alfalfa. This led us to feed lambs and cattle and to save the manure with care. Later study of the use of manure showed us that there was great waste when manure was let stand in the yard till fall before it was hauled out. Therefore we made practice of drawing it at once to the fields and spreading it nearly as fast as it was made. This practice we yet observe. Manure in the soil does very much more than add fertility. Probably we do not know nearly all that it does. First, doubtless it directly feeds the soil. There is nitrogen in manure, some small amount of potash, and a little more phosphorus, though not nearly so much phosphorus as there should be to make a balanced ration for plants. But manure brings in myriads of bacteria. These bacteria aid plant life and plant growth. Where manure is the special nitrifying bacteria abound. The bacteria too that attach themselves to alfalfa roots and clover abound much more in soils filled with manure. Manure Brings Inoculation. — It is seldom if ever necessary to inoculate land for alfalfa when it has been well enriched with manure. I once saw a field sown to alfalfa in C'anada that was so well inocu- lated that in six weeks after the alfalfa was sown the tiny nodules were found on the roots, and this field was the first sown in that neighborhood, nor was it artificially inoculated. It had simply been well manured. In other states I have seen the same 152 ALFALFA FARMING IN AMERICA. curious result. In Iowa on the experiment station farm at Ames a field was sown in alfalfa. All the seed was sown the same day and in no way was the treatment of one part of the field different from the treatment of any other part, yet there was se- cured a fine stand of thrifty alfalfa on one side of the field and very thin and poor alfalfa on the other side. The explanation seemed to be that on a previ- ous year one side of this field had been manured and sugar beets grown thereon. Yet all the field seemed very fertile and Director C. F. Curtiss thought that planted in corn all of the field was rich enough to grow 80 bushels to the acre. But that addition of some stable manure a year or two previously made one side of -the field eminently fit for alfalfa, while the other side remained in unprofitable condition so far as alfalfa was concerned. From experience I feel sure that I had rather take a rather poor piece of land, well manured, for alfalfa growing, than a naturally rich piece of land with no manure. In truth some of the heaviest alfalfa I have ever seen grew on "Woodland Farm on soil naturally very in- fertile, though well filled with lime, after the field had been well coated with manure, the manure turned under deep and alfalfa sown. One day I was plowing in this self same field when a curious thought came. A flock of black birds was following the plow, hopping eagerly along and keeping up animated discourse, meanwhile busily searching for something. What they were after, of course, was earth worms. The thought then came, MANURES AND HUMUS IN SOIL. 153 "Why, here is the best indication yet of whether alfalfa will thrive in a field. If the black birds fol- low the plowman it is sure to grow ; if no black birds come let him beware how he sows alfalfa." It is indeed a true indication for all eastern soils; there may be lands in the South and West where the earth worm is not a sure indication. Earth worms thrive only where there is humus in the land. They do a most useful work in opening the soil by means of +heir tunnels to let in air and let out water. They bury up vegetable matter and promote bacterial life. Where earth worms are the soil is evidently drained, although it may not be drained deep enough. Alfalfa Loves Rich Soils. — The plain truth is that thousands of men all over the eastern states of America have tried to grow alfalfa on-land too poor for it. Alfalfa loves fertile soil. In turn it adds greatly to the fertility of any land on which it grows. It is an energetic soil enricher, but it will not en- rich poor soils. That may be a pity, but it is after all in the order of Nature. "To him who hath shall be given. ' ' One must have fertility in order to trap more fertility. No other available plant will gather so much fertility as the alfalfa plant. A field of it will gather nitrogen largely, the hay may be fed, the manure saved, another field enriched and sown to alfalfa and thus the fertility will spread from the one spot of infection till all the farm is covered. But only by beginning right, by making one field rich and dry and sweet, getting it set in alfalfa, 154 ALFALFA FARMING IN AMERICA. then from the manure of that field spreading to an- other, can a man succeed. It is easy once you get started. The farther you go the faster the work proceeds. I write now of rather poor eastern soils. Of course there are soils already so rich in all needed elements of plant food that it is idle to add more, Men owning such soils are more blessed than they probably realize. Soils Devoid of Humus. — Will not alfalfa grow in soils devoid of humus! It is an interesting ques- tion. I feel that it will, under certain conditions. There are desert soils that would seem to be almost devoid of vegetable matter, yet fully charged with mineral salts and in these I have seen the most tre- mendous alfalfa that I have ever seen. Perhaps there was more humus in that gray-colored lime- impregnated alkaline soil than I thought, but it certainly was as hard as brick when dry and of the color of lime mortar. It is sure, however, that in eastern soils humus is most desirable; how indis- pensable it is remains to be worked out. An Example of Farm Practice. — On Woodland Farm there is one 60-acre field commonly called the Gill field. It has not long been a part of the farm. The soil was clay, some of it white and some of it black. A part of the field was low and peaty. For many years it had probably not paid the cost of cul- tivation. It had had little or no manure since the forest was cleared away. The first step was to get rid of surplus water and miles of ditches were laid, one of them to give out- MANURES AND HUMUS IN SOIL. 155 let being for some distance 10 to 12 feet deep. The usual depth was 3 to 4 feet. Then a very little stable manure was spread over the field and red clover was sown with beardless spring barley as a nurse crop. With the clover was sown a fertilizer com- posed of tankage and acid phosphate. The barley was cut oft' for hay and the clover came on and made a fair growth. It was a good stand and had a healthy look, which no one remembered seeing on this field for many years. The clover was cut for hay and seed, and a trifle more of manure spread over the ground. It is evident that on a 60 acre field one will not strew manure very thickly unless he has access to a very large store, and only the farm barns and feeding yards could be drawn upon. The land was then plowed and planted to corn, making about 55 bushels per acre. Its previous crop had been about 20 bushels. On the corn stubble more manure was spread in 1904 and again the land was sown to clover with a nurse crop of beardless spring barley. This time it was hoped that the field might be dry enough and fertile enough to take al- falfa, so a mixture of alfalfa, was put with the clover, about 10 per cent or a little mo>re. Again the barley was made into hay. This time the clover was a glorious success, yield- ing more than double what it had yielded the first year and the alfalfa came in strong for the second cutting. It was vigorous over nearly all the field. In the spring of 1906 the field was again sprinkled somewhat with manure and plowed for corn. The 156 ALFALFA FARMING IN AMERICA. yield that year was about 90 bushels. Again with a light coating of manure it was put in corn. This time the yield was 85 bushels. For the corn crop a dressing of 400 pounds per acre of raw Tennessee rock phosphate was applied. Just what effect this had we do not know, as we left no test strips. It probably was of material benefit, however. Once more a light application of manure was made. In truth the applications of manure were all light except on certain spots of exceptionally poor white clay. The land was plowed again and seeded (in April, 1908), to alfalfa with a nurse crop, as usual, of beardless spring barley. With the seeding was sown fertilizer, plain acid phosphate, analyzing about 16 per cent available phosphoric acid, at the rate of 250 pounds per acre. 1908 proved a very dry summer yet a splendid stand resulted over the whole field. A crop of bar- ley hay was cut and later a light crop of alfalfa hay, probably not quite one ton to the acre. From the window where I sit I look out afield across this very stretch of land. It is (May 5, 1909,) a glorious sight. Aside from a few wet pond holes there is not a square foot of the land that is not covered with green and growing alfalfa plants. That field should make near 5 tons of hay this year. And every year since the manure spreader started over the tiled fields the land has paid well. It is not probable that alfalfa would have made a strong growth on this field without this slow bring- ing-up process. The land was too run down, too de- MANURES AND HUMUS IN SOIL. 157 pleted of humus. Could more manure have been spared doubtless the field could have been gotten ready for alfalfa earlier, but it was not available, so red clover, which is less exacting, came in first and paved the way. Methods of Using Manure. — While there can be no question of the value of manure for alfalfa yet there are several ways of using it, some much more successful than others. It is seldom good practice to apply heavy coats of manure and at once sow al- falfa. The trouble is from the strong growth of weeds and annual grasses that will result and which may in part smother the alfalfa. Manure is often filled with weed seeds, has tendency to rush rapidly all weeds that naturally spring up and these worth- less things outgrow the little alfalfa plants. Weeds may usually be subdued by mowing off the field two or three times during the season, but there is danger in mowing young alfalfa at the wrrong time which sometimes destroys it. Briefly, alfalfa ought not to be cut till little shoots appear on the bases of the stems. These shoots appear as buds which de- velop into new stems. Before these shoots appear it sometimes quite destroys alfalfa to cut it off ; this is especially true the first season of its existence. So one can not mow off weeds till these little shoots come. The writer has more than once seen efforts made to force alfalfa to grow by heavy manuring when what it really needed was liming. The only result was a worse crowding by weeds. It is very much better to apply a heavy coat of 158 ALFALFA FARMING IN AMERICA. manure and plow it under the preceding year, then plant a crop of corn and keep the crop absolutely clean of weeds and grass so that no seeds will be formed. This gives pretty clean land for alfalfa sowing the succeeding year. Impossible to keep corn land clean, say you? It is neither impossible nor very difficult. On Woodland Farm it has been found that about 5 plowings with two-horse culti- vators followed with two goings through with one- horse garden cultivators of the many shoveled type, kept the corn almost absolutely clean, and men with hoes rapidly completed the work. A good stand of corn greatly helps here. Eradicating Fox-tail Grass. — Fox-tail or pigeon grass (Chaetochloa glauca) is one of the worst ene- mies of alfalfa in all eastern America. It is an an- nual grass that becomes very thick in young mead- ows and sometimes in old ones. Mowing it off does not prevent its going to seed, in fact mowing it off only seems to make it grow thicker. It cannot be eradicated by disking in new alfalfa fields. Take it all in all it is the worst pest of alfalfa in the eastern states. Crab grass is next to it, but crab grass does not trouble where there is plenty of lime in the soil, while fox-tail is no respecter of lime or anything else. Fortunately fox-tail has its weak point; its seeds do not live long in the soil but soon germinate there and grow. On Woodland Farm we have kept a corn field absolutely clean for one year, and next season sown the land to alfalfa, with the result that we did MANURES AND HUMUS IN SOIL. 159 not see a single plant of fox-tail on a square rod, and this over a great part of the field. Just destroy the plant absolutely before it seeds during one year and you have it conquered. Growing Humus-making Crops. — Not every farm- er has access to a manure heap. Some have too much land, some have too few animals. Thus many who wish to grow alfalfa desire to grow on the land some crop that will help fill the soil with needed humus. What is available for this purpose! Very much depends here upon the location. Cowpeas. — In Tennessee, and probably in Ken- tucky, the cowpea is a good forerunner of alfalfa. The cowpea has several excellent qualities. If a vigorous growing variety is chosen it covers the soil all over and shades it. This shade promotes the gathering of nitrogen as we have long known. The pea vines smother weeds and so help clean the land. Their roots, abundantly supplied with nodules, gather nitrogen and store it in the soil. After cow- peas the soil is also much more friable than it was before. The vines may be left to lay upon the land, disking them and turning them under, or may be cut off for hay. Certainly one gets more humus to turn them under. In the South a crop of cowpeas may be grown and the land plowed and sown to al- falfa the same year. This is not practicable north of the Ohio River. Morgan found in Tennessee a very great increase in alfalfa yield when it was sown after cowpeas. Turning Under Green Cowpeas. — There seems a 160 ALFALFA FARMING IN AMERICA. somewhat greater danger of souring land when green crops are turned under than when they are left to ripen and decay somewhat on the surface be- fore being turned under. It is not easy to account for this fact. It is always well when turning under cover crops where alfalfa is to be sawn to* use a larger application of lime than one otherwise would use, since thus he avoids the danger of souring the land. Cowpeas however, may do soils good and may pos- sibly do them harm. It has been taught that cow- peas always build soil, whether the vines are taken away or left on the soil to be turned under. Prof. C. A, Mooers of the Tennessee Station has shown that cowpeas when cut and removed from the soil have a marked effect in depleting it of fertility. Probably they rob it rapidly of available phos- phorus. It is plain that when cowpeas are grown to prepare the land for alfa'lfa seeding they ought to be turned under, not taken away from the land. "Cut them and put the manure back!" Yes, but would it come back? The Soy Bean. — An easier crop to grow than the cowpea is the soy bean, and it also is a soil enricher and affords much humus when turned under. Soy beans are of many sorts. The large growing kinds, like the Mammoth Yellow, make the most vegetation for turning under, while smaller growing sorts make most seed in northern latitudes. Soy beans to do well need soil inoculation. It will come of itself if they are continuously grown on the same land. Soy MANURES AND HUMUS IN SOIL. 161 beans are drilled in drills about 24 inches apart and cultivated carefully till they cover the land, when their shade suppresses weeds. To get a money crop out of soy beans and yet have a hot of humus-making material is easy. One does it with hogs, turning them in after the bean crop is mature and letting them harvest the beans. Afterward the stems remaining with many leaves will be plowed down. Soy beans respond well to fertilization with phos- phatic fertilizers. The larger grows the soil-build- ing crop, whether of soy beans, cowpeas, crimson clover or anything else, the larger the alfalfa will grow after it. Therefore fertilizer applied to the cover crop is all to the good. Crimson Clover (Trifolium incarnatum). — One of the most charmingly beautiful clovers is crimson clover, the trifolium of the English farmer. It is an annual clover. Sown in summer it makes a fall and winter growth (if there is any open weather) blooms in May, ripens its seed and dies. It is of no use sown in the spring. It is much used in Eng- land, France and the Middle Atlantic States of America. It is a good forerunner of alfalfa. This plant is remarkably cold-resistant and in suitable soils grows during every warm spell of winter. It enriches soils admirably if it has itself the right bacteria at work on its roots. On some soils where it is new it needs inoculation. Crimson clover is sown in late summer or early fall, usually as a catch crop after corn or garden truck. It makes 162 ALFALFA FARMING IN AMERICA. rapid growth during the late season and starts early in spring. It is easily established if sown in late July or August. It will not endure heat so is of no use sown in the spring. It grows during cool weather. On the other hand it will not endure extremely cold weather, and is usually killed by repeated freez- ing and thawing of spring in the region of the corn- belt. It is especially at home in Maryland, Dela- ware, New Jersey, Virginia, and in fact all along the Atlantic seaboard. There it is an admirable catch crop and forerunner of alfalfa when one is desirous of bringing in large areas to meadow with least possible delay. Eoberts -shows that the fall growth of crimson clover in New York, taken on Nov. 2, yielded as much as 155 Ibs. of nitrogen per acre and doubt- less the spring growth would have yielded in ad- dition even a greater amount had not the plants killed out during the freezes of spring. Nitrogen is difficult to buy for less than 15 cents per pound and often costs much more, so it is clear that the crim- son clover had done a lot of work at nitrogen-gath- ering very economically indeed. Using Crimson Clover. — A good way to use crim- son clover is to sow it in the corn at last working, or to disk up an oat or wheat stubble and sow it there. The latter way will give sure results. Use phosphorus in some form to stimulate the crimson clover, since the better it thrives the more it will do for you and all will be kept in the soil for the MANURES AND HUMUS IN SOIL. 163 use of the succeeding alfalfa in any case. Acid phos- phate works well with crimson clover; put on 200 pounds of it per acre, choosing always a grade analyzing a good percentage of available phosphoric acid. It likes a good seed bed too. Mix with it 10 per cent of alfalfa, and if the land has never had on it either alfalfa or crimson clover, get some infected earth from an old field of each of the plants. Infecting a Field. — One can use rather a small amount of earth and get good results in inoculat- ing a field if he does it in the right manner. Let him get as little as 100 pounds of earth from where crimson clover has been grown and 50 pounds of earth from an alfalfa field or a sweet clover patch and mix these together and pulverize them well. Do this away from the sun. Then mix the crimson clover seed, say 15 pounds and say 2 pounds of alfalfa seed with the 150 pounds of infected soil. Sow this altogether on an acre of land. Sow it if you can late in the day, or at any event follow the sower with a harrow that will at once stir the land and cover seed and infected soil. Sunlight is fatal to inoculation. The result will Be that both sorts of plants will grow well together and the alfalfa plants, while much more feeble in growth than the crimson clover, will yet hold its own pretty bravely and will be- come inoculated and thus will prepare the land for a single seeding of alfalfa next year. Crimson Clover for Pasture and Hay. — The crim- son clover will make good pasture in the fall and 164 ALFALFA FARMING IN AMERICA. early spring. Do not pasture it much if you wish the full benefit of its nitrogen-gathering and humus- making. Before the seed forms, and as early as it flowers, it can be made into hay. Crimson clover hay is nutritious, only when cut too* late it has a bad habit of sometimes killing animals by forming hair balls in their stomachs, so it is best to let it ripen and take off a crop of seed, putting the straw back, or else to plow it under and use all the growth as a manure. Do not expect crimson clover to do much without inoculation. This comes in more easily with crimson clover than with most other legumes. Alfalfa Following Crimson Clover. — As soon as the crimson clover is turned under begin cultiva- tion of the land and get it in fine tilth, destroying any weeds that may spring up. Do not sow the alfalfa seed till the soil is well stored with moisture. After every rain go over the field with some efficient sort of harrow. If the land is not hard a spike tooth drag harrow is one of the best implements of summer culture. Should rain make it hard and in danger of baking, the disk or spring tooth may be needed. The lime may be put on now, though it would have been better to have put it on before the crim- son clover was sown so that it could be doing its quiet work of sweetening the land. As soon as the land is stored with moisture, say by the last week in July or some time in August, the alfalfa may be sown alone. One ought to ob- MANURES AND HUMUS IN SOIL. 165 serve carefully the scattered alfalfa plants that grew in the crimson clover to see if they were in- oculated, so as to know whether to do anything further toward inoculation of the land before sow- ing to alfalfa alone. Nodules on the Roots. — If he finds the alfalfa plants vigorous, of thrifty growth and dark green color, he may make a good guess that they are safely inoculated. If they are feeble, pale, spindling, yel- low, he may well doubt the inoculation having "taken." To make sure let him very carefully dig up alfalfa plants and wash off the earth from their finer root hairs. The nodules are easily seen when present, though one can seldom get them by pulling up a plant, since they are so easily stripped off, their attachment to the roots being delicate. They are of light color, about the size of alfalfa seeds or a little smaller and are sometimes, when conditions are good and lime is plentiful in the soil, set on like bunches of grapes, though usually they are found singly on the little root hairs. Crimson Clover in Conclusion. — Crimson clover is a plant better adapted to cool weather than to hot, to England and France, where it thrives, than to regions where grows the royal maize plant. In Eng- land it is termed trifolium and is highly esteemed for soiling in May. It thrives best in sandy soils along the Atlantic seaboard and will probably never be of much importance west of the Allegheny Moun- tains or north of the Ohio River. But in Virginia it is a great aid in getting alfalfa set on old fields 166 ALFALFA FARMING IN AMERICA. needing humus sadly. It has failed in countless in- stances because of lack of inoculation. If one wishes to grow it he should either inoculate with soil from some successful crimson clover field or should per- sist year after year in growing it on the same soil till at last the inoculation comes. There seems a wild clover along the Atlantic Coast that carries the same bacteria as' crimson clover but this is not found west of the Alleghenies. With proper inocu- lation crimson clover will succeed over a far wider territory than is now known or supposed. Melilotus or Sweet Clover. — What is a weed? A plant out of place? Weeds there are and weeds. If one must have them, and usually, he will, he could hardly have a better one than Melilotus alba, or white sweet clover. There are two sorts of sweet clover, one with white blooms and one with yellow. The yellow-flowered sort is Melilotus officinalis. It is not so good as the white nor so common. Sweet clover looks like alfalfa. Indeed, it is a sort of first cousin to the alfalfa plant. The main difference is that it has a less deeply boring root stock and is a biennial, or a two-year plant, while alfalfa may live half a century. Sweet clover is a good sort of weed, because it is not unsightly and it feeds the bees and wherever it grows it mightily enriches land. It loves lime land and hard places along roadsides and on railway embankments. It will grow 6 or 8 feet high in favorable places or if it is cut down close it will bear seed when only just above the earth. It was Dr. Cyril G. Hopkins who first called at- MANURES AND HUMUS IN SOIL. 167 tention to the fact that alfalfa and sweet clover bear the same bacteria on their rootlets and that sweet clover inoculates land for alfalfa. (Breeder's Gazette, Sept. 16, 1903.) So there is quite a use- ful combination of facts. Sweet clover is very hardy, it will grow on poor soil, it enriches soil very much and it improves the physical condition of soils, then it inoculates the land for alfalfa. In truth many fine fields of alfalfa have had their start from inoculation taken from sweet clover weed patches along roadsides. Melilotus has never been treated as a farm crop in the North. In the South it is much used in Alabama and Mississippi, both as pasture and for hay. No better authority on meliMus could be found than Prof. J. F. Duggar, Director of the Alabama ex- periment station. I quote from a letter from him: In reply to your request, I give you the following data on Melilotus alba (sweet clover), as it is grown in the central prairie belt of Alabama and Mississippi. The seed should be sown in February and lightly covered. It may be sown either on ground devoted entirely to this crop or sown with seed oats or among growing plants of fall-sown oats. At least one bushel of unhulled seed per acre is needed. If sown alone and on good land there will usually be one or two cuttings the first year. If sown with oats as a nurse crop and on poor land, the first year's growth will scarcely be sufficient for cut- ting, but will afford a fair amount of pasturage. The second year new shoots spring from the old crowns early in March and the first cuttings of hay can be made early in May. There is usually a second cutting. Melilotus should be cut when just beginning to bloom, since after this date it rapdly becomes woody. The hay, especially that secured the year the seed are sown, is very nutritious, the composition resembling that of alfalfa, though melilotus hay contains a smaller proportion of leaves, and the stems are coarser, especially in the hay secured the second year of the plant's life. At first live stock do not 168 ALFALFA FARMING IN AMERICA. relish either the hay or the green plant, but in time most ani- mals eat both with apparent relish, though always preferring grass and other legumes. Sweet clover seeds abundantly in its second year of growth and will thus occupy the land continuously if not destroyed by cultivation. It never makes a full stand except on lime land. Soil deficient in lime, but made up largely of clay, often pro- duces individual plants of thrifty growth, but I have never seen on such land a stand thick enough to be profitable. The chief value of melilotus is for the renovation of the stiff, waxy, lime soils of the central prairie regions of Alabama and Mississippi where the subsoil is a soft or rotten limestone. In Alabama yellow melilotus is not at all comparable in value with white melilotus. The yellow comes up earlier in winter, blooms in April, and is dead by June. It never attains the size of either top or root attained by sweet clover and hence is not equal as a renovating plant. Moreover, the bitter principle is much stronger in yellow melilotus, so strong indeed as to taint the milk and butter made from it, a condition that rarely if ever occurs with white meli- lotus. Note the curious fact that sweet clover like alfalfa revels in lime land. I have seen it growing with great luxuriance in piles of crushed limestone rail- way ballast where one would hardly think any plant could find sustenance, but that railway ballast was of limestone and full of limestone dust. Use of Sweet Clover. — Here would seem to be the correct use of melilotus, for making land ready for alfalfa. If it is land deficient in lime put on ground limestone enough to make it alkaline, or else use burned lime if the ground limestone can not be had. Then in case the land needs humus and fertility to be made ready for alfalfa, sow to melilotus for two years. There is no magic about melilotus probably aside from the magic of its bacteria, and it will grow the better for fertilization, so fertilize it with MANURES AND HUMUS IN SOIL. 169 an application of about 250 pounds per acre of high grade acid phosphate or some better phosphate car- rier. Inoculate the seed when it is sown. That is easily done if one can get earth from some alfalfa field or some sweet clover patch. Not much earth is needed; 100 pounds of earth is ample for an acre. Dry the earth in the shade, spreading it out on the barn floor, and shoveling it over now and then, mak- ing it fine. Mix the earth with the melilotus seed and sow together. Melilotus seed is sometimes seen in the hull, though seedsmen usually sell the cleaned seed. It resembles alfalfa seed almost ex- actly, being sometimes a trifle larger. It weighs 60 pounds to the bushel cleaned. To sow 15 pounds per acre of cleaned seed would doubtless give a stand. Mix this with the 100 pounds of inoculated soil and sow together, for thin land long run with- out manure, land too poor for alfalfa. If it is rich soil one would best sow alfalfa at once and be done with it, but if the soil needs building first, probably the sweet clover plant is as good a thing as one can build with. It is especially adapted to worn soils (after liming or naturally filled with lime) in south- ern states. No Fear of Pest. — Some fear may be entertained lest the sweet clover becomes a pest in the land. There is no danger of that. Simply mowing the plant will destroy it as it is a biennial and must seed every second year. It often appears in alfalfa fields the first and second years after starting and sometimes the seedsmen are harshly criticised for 170 ALFALFA FARMING IN AMERICA. selling adulterated alfalfa seed. Nearly all western seed will contain a little sweet clover seed and no seedsman probably can detect it or clean it out. It is not a serious injury to the alfalfa and disappears completely the third year when the alfalfa is mown off in regular rotation. There is never any difficulty in getting rid of melilotus when one gets ready to dispose of it. It is very much hardier than alfalfa and probably a better forager for plant food; cer- tainly it thrives on poorer soil than alfalfa does and it does very much to make the land ready for alfalfa wherever it grows. It does not ask for as deeply drained land as do'es alfalfa. On the other hand animals usually scorn to eat it, though I have seen it eaten with relish by sheep, pigs and cows in Alabama, and the animals throve. The seed usually sells a little cheaper than alfalfa. Should there develop much demand for it there would be large profit in producing seed on suitable soil, since it seeds very freely almost anywhere, while alfalfa does not. Melilotus in Kentucky. — As indicative of what melilotus is doing in Kentucky we quote the follow- ing extracts from letters written by J.. T. Mardis, from Pendleton County: As an illustration of its value, I will explain that seventeen years ago I bought one hundred acres of as badly worn and washed land as could be found anywhere, My first resolve and constant efforts following was to improve and get in grass, and to obtain these results I worked all my spare time, year after year, filling washes with any material to be had, plowing, harrowing and sowing grass seeds and seeds of many different plants advertised and recommended for improving land, for which MANURES AND HUMUS IN SOIL. 171 I spent hundreds of dollars, but as the land was too poor to take in grass to do any good, the labor and seed were lost, as the condition of the land grew worse with each season until seven years ago, when I took up sweet clover, with the result that to- day the land is in fine shape, either being cultivated and produc- ing good crops or in fine blue grass sod, and while producing this effect the land yielded an abundance of pasture and hay. And oh, what a relief to be rid of the sight of those unsightly barren and washed hillsides. It is a biennial, makes fine pasture the first season and abundant crop of pasture, hay or seed the second season. There are two varieties — white and yellow — the latter being generally preferred for hay, as it does not grow so coarse; it grows from two to four feet high, while the white will double this growth under same conditions, and makes splendid hay if properly man- aged; makes more and later pasture and builds land up much quicker. Each is good for all kinds of stock; does not bloat cattle or sheep; is one of the best honey plants known. It is a leguminous plant, the strongest within our knowledge. When once established it requires no further seeding as it reseeds itself. After it has once seeded, the land may be cultivated two or three years and a good stand follow without reseeding. Sown at any season of the year, you are sure to get enough to secure a catch by waiting and allowing it to seed and spread, but of course it is desirable to get a good stand at once, for which I advise sowing from Dec. 1 to March 1, on top of land without covering. Or if sown later, say to the first of May, it should be harrowed or brushed in. It can be sown with small grain of any kind either in spring or fall. If sown in early fall it should be covered sufficiently deep to prevent germination until spring. Good results are had by sowing on stony washed and barren hills during the winter months without previous preparation of the land, as the - seed will be carried down by the frequent freeze and thaw. The seed should never be sown on snow or hard frozen ground, as it is liable to be carried off by following rains. Good blue grass sod can be had in three to four years on this class of land by sowing the two seeds together; all grasses do much better grown with sweet clover. To illustrate the rapidity with which sweet clover is gaining favor, I will state that in 1903 I saved one bushel of seed. In 1904 I saved four bushels of seeds. I wrote articles which were published in the county paper, describing its habits and quali- ties. I continued to recommend it locally; and in 1905 saved 172 ALFALFA FARMING IN AMERICA. thirty bushels of seed which were readily taken, and later in the season the demand could not be supplied at any price. As a re- sult hundreds of acres of land in this and in one or two neigh- boring counties, so worn and washed that it was almost worth- less, has been and is being brought back to a state of productive- ness and value. In regard to seed, there seems to be no established market as to prices or number of pounds per bushel. It is sold at all kinds of prices per bushel, the bushels ranging from 14 to 60 pounds per bushel. There is also a vast difference in the quality of the seed, as to how it is cleaned and handled, as it heats very readily even in small bulk, consequently there is much dead seed sold, which fact has discouraged many would-be growers. I recommend the sowing of unhulled seed as a cheaper seed as something else is often substituted for the hulled. It should be cut when the first blooms appear and handled much the same as other clovers, giving a little more sunshine, according to weight of crop. For hay I advise sowing the yellow blossom variety on hand where the machine can be run. More feed of fine quality can be had per acre from this plant than any grass I have ever seen. For improving land and for grazing I strongly advise using the white variety. I do not recommend sweet clover for low or wet land. We have recently purchased 200 acres more of the same class of land" and will soon have this in the same present condition of the first 100 acres purchased. During the spring of the ex- tremely dry season of 1908 we broke for corn an old timothy meadow where patches of sweet clover had been started, and all during the season, after the corn had started, it was easy to see where the sweet clover had grown, and these spots were the only part of the field where we had any corn which was fairly good, and the rest of the field yielded only fodder of poor quality. Mr. James Thompson, an all-round business man and director of the Pendleton Bank at Falmouth, has purchased a few. hun- dred acres of worn out land which he has seeded to sweet '.clover and is well pleased with the investment and says he knows of no other plant so valuable to those having worn out or washed land. Mr. J. S. Gardner, Kelat, Ky., stock buyer and shipper, says: "The fattest sheep and cattle I handle are those from sweet clover pastures." Milch cows fed on sweet clover hay yield an abundance of milk from which is made nice yellow butter. Stock cattle, young horses and mules do well on the hay without grain. MANURES AND HUMUS IN SOIL. 173 Land is just as easily broken after a heavy crop of sweet clover as after common red, if plowed before the seed plants have made too much growth. Seedling plants do not interfere with wheat. The yearling plant is a little in the way of harvest- ing, but does not injure the crop, unless it should be very thick. It will grow just as well on the poorest stony washed limestone land as on the best of soil. The land cannot be too dry and hot for it to succeed. It does prepare land for alfalfa by loosening, enriching and furnishing the necessary bacteria. It is a drouth resisting plant, and continues to grow through the dryest sum- mers, furnishing an abundance of grazing, while other grasses are parched, and remains green until quite hard freezing. Sweet clover is all right on good land, but it is the man with the worn land who needs it most. On dry land such a thing as an entire failure is out of the question if good seed is sown, no matter at what season of the year, but of course you may expect best re- sults from spring seeding where the seed is covered by any means convenient, or from early winter sowing, when nature will do the covering. When sown for hay I use one bushel of seed to four acres, for grazing or improving land one bushel will be suf- ficient for five or six acres. If sown late in the season and the weather is dry the seed will lay over to the next spring and come all right. Some of the best stands I have ever had were obtained from such conditions. Some of the statements made may seem a little extravagant to those not familiar with the plant, yet there is not a particle of exaggeration. Just imagine a growth from six to eight feet high and so thick a man can scarcely walk through it, being left on the land to enrich it and stop wash and to be followed without cost the next season with a growth of seed plants that will form a dense sod and grow to the height of two to three feet, and this process repeated year after year, and add to this the fact that this plant unquestionably attracts to the soil more than double the amount of nitrogen that red clover will under the most favor- able conditions. Can you then wonder that land is so rapidly im- proved?" In Wyoming. — The Wyoming experiment station reports that lambs fed upon sweet clover hay relished it and throve. It was found that they digested it ex- ceedingly well, and that it contained a very large percentage of digestible protein. It is well known 174 ALFALFA FARMING IN AMERICA. that animals usually refuse to eat green sweet clover. It seems that when made into hay, with a little salt added, they relish it. The Wyoming experiment is thus reported: Sweet clover throughout most of the eastern states is consid- ered as a weed and is treated as such. At this altitude, under our peculiar conditions, it is believed by a few that there is a fu- ture for it, since it grows well. It is an alkali-resisting plant and, although it is not palatable to stock in the green condition, yet after it is cured, especially where salt has been added, the stock relish it and thrive well upon it. It is very nutritious, readily digestible, and contains an exceedingly high percentage of crude protein. It is more nutritious When cut at the proper period than many of the other hays. The sweet clover hay used in this experiment was grown on the experiment station farm near Laramie in 1905. It had been in stack for over a year before being used for this experi- ment. It was very rank at the time of cutting and the amount of stems, therefore, very large in proportion to the leaves. The stems had become rather hard and woody. Notwithstanding this, the hay proved to be a very narrow ration, since the nutri- tive ratio was only 1:3.2. The crude fiber did not run as high as would have been expected, being but 24.75 per cent.

It seems that the great objection to the hay is the flavor and the fact that it becomes woody if it is allowed to ripen. It is believed that there are possibilities for this plant in Wyoming if it is cut at the right time and properly cured and cared for. It grows well and the yields are large. The nutritive ratio is 1:32.2, as found by this experiment, which makes sweet clover a narrower ration than alfalfa. PHOSPHORUS FOR SOILS. Phosphorus is the "life" of the soil. Scientists are not agreed as to the function of phosphorus in the soil, some contending that as applied it is merely a sort of disinfectant, as it were ; that it de- stroys certain toxic or poisonous conditions hurt- ful to plant life. Certain it is, however, that soils well stored with available phosphorus are produc- tive of the right sorts of useful plants. Soils well stored with phosphoTus are rich soils, grow rich plants and make splendid animals. The soils of the central blue-grass region of Kentucky are so rich in phosphorus that the addition of more can not usually be seen in the crop. They are rich too in carbonate of lime and from these soils grow the best grasses in the world, and the horses and cat- tle feeding on these grasses are famed the world around. Soils that are p'oor and unproductive are usually much helped by applications of additional phos- phorus. Alfalfa especially responds to this element. Basic Slag. — Basic slag has already been men- tioned. It is a refuse left from making steel. Cer- tain ores rich in phosphorus make bad steel unless that element is taken out of them. John W. Pater- son of West Scotland Agricultural College, Glas- gow, in an admirable pamphlet on use of "Basic Slag on the Farm," says: The essential constituents of manures are nitrogen, potash (176) PHOSPHORUS FOR SOILS. 177 and phosphoric acid for the sake of the crop, lime for the sake of the land. At the outset of cultivation size of crop will generally be de- termined by the supply of the first three. After a term of years the ability of the soil to respond to fresh applications of artifi- cial manures will largely depend on its holding a sufficiency of lime. The use of most of the ordinary artificial manures involves the washing out of lime into the drains. Thus the application of 1 cwt. sulphate of ammonia will, in ordinary circumstances, cause an ultimate loss of more than its own weight of available lime compounds in the drainage of waters. After a long period of artificial manuring the use of ground lime as a soil corrective has been rapidly gaining prominence in recent years. It is in view of this fact that among all artificial manures basic slag possesses a special interest. While primarily em- ployed as a phosphate, it contains ground lime as an accidental constituent. Bones do not cause waste of available lime com- pounds from the soil. Basic slag actually increases them. All other artificial manures in common use, nitrogenous, phosphatic and potassic, cause a gradual washing away of the lime com- pounds from the land. Manures are applied not because the land is ever actually deficient in nitrogen, potash or phosphoric acid at the time. They are applied rather because the natural supplies of these are in a form unsuitable for absorption by plants. The importance of lime in land is that it hastens the conver- sion of the natural soil constituents into available forms. This effect is exercised on the phosphates, on the potash, but above all on the nitrogen. The general effect of liming on newly broken in land, especially on peats, which are commonly deficient in lime, is sufficient evidence of this. Leguminous crops, including clovers, vetches and beans, do not require nitrogenous manures because they are able to utilize atmospheric nitrogen. Lime greatly strengthens their power to do this, thereby giving larger crops and enriching the land in nitrogen at the same time. Basic slag has the same power part- ly owing to the extra lime which it contains, the effect being usually best seen in the stimulation of clovers in pasture leys. Basic slag is a by-product in the manufacture of steel by the basic process. Pig iron frequently contains phosphorus; and steel made from this is brittle unless the phosphorus is removed. In the process of manufacture a blast of air is forced through the molten pig iron, whereby the phosphorus in the pig is burned to 178 ALFALFA FARMING IN AMERICA. give phosphoric acid. This acid then unites with lime thrown into the molten metal for the purpose. A phosphate of lime is formed. This rises to the surface of the metal as a fusible slag, and is subsequently poured off and cooled. A dark, brittle, hard mass is obtained, which is capable of extremely fine grinding in roller mills. In 1886, Dr. Hilgenstock showed that basic slag phosphate ex- ists as a hitherto unknown compound of phosphoric acid and lime, viz., a tetra-basic phosphate (CaO)4P2O5. Later investiga- tions showed that this phosphate, if only sufficiently ground, passes easily into solution even in very dilute acids. In a sample shaken up with peat and water, 78.8 per cent of its phosphate was dissolved in 14 days. The suitability of basic slag phos- phate for direct absorption by plants was thereby demonstrated. The special characteristics of basic slag as a manure are (1) the easy solubility of its phosphate in dilute acid, (2) the pres- ence of free lime giving what is chemically called an alkaline re- action. In both these respects basic slag is superior to bones. Super-phosphate, the other principal source of phosphoric acid, is superior in solubility, being water soluble, but inferior in its general effect upon soils, being deficient in lime. These differ- ences in character of the three manures are seen in their relative effects as crop-producers in carefully conducted experiments. The capacity of leguminous crops to utilize atmospheric nitro- gen renders nitrogenous manures generally unnecessary. For the same reason farm yard manure, which supplies much nitro- gen, can in most cases be better utilized upon some other crop. The most profitable return will in ordinary practice be obtained from a dressing of artificials supplying phosphates, potash and lime. Beans, vetches and peas are all lime-loving crops, and for this reason basic slag is well suited to their requirements. Belonging to the same natural order are sainfoin, lucerne and clover, im- portant forage crops. For these, 5 cwt. basic slag, and 2l/2 cwt. kainit in autumn, is recommended as a suitable application, with 3 or 4 cwt. superphosphate, and the same quantity of kainit again in spring. The quantities stated may require to be increased or diminished according to the fertility of the land. While the necessity of applying manures to land under crop is now almost generally recognized, the claims of pasture strangely enough are almost wholly neglected. Recent investiga- tions have shown, however, that this is a mistake. More es- pecially is this the case with the medium and second-class pastures, whicn form such a large proportion of our grazing area. PHOSPHORUS FOR SOILS. 179 Practically speaking, all such pastures will yield a profitable return to a suitable application of manures, and in some cases the natural yield may be even trebled. Attention was first directed to the improvement of pasture land by Dr. Somerville, while director of the Northumberland County Farm at Cockle Park. His experiments were started in 1897, an'd the results to date are published in a report by his suc- cessor, Prof. Gilchrist. The plots receiving different manurial treatment are each 3 1-20 acres — three acres being grazed each summer, while the odd fraction is cut for hay. The live-increases of the sheep and the yields of hay are carefully noted during each year, and compared with the unmanured plot. Ten differ- ent systems of manuring were contrasted in the experiments, but the following four only need be referred to, as they were most profitable of the various methods: PLOT. MANURES. Cost of manures. Mutton produced (6 years). Profit from manures II;-y per acre (6 years) 6 Unmanured . ... 246 Ibs. 59 cwt. 3 10 cwt slaf 1897 22 s 822 Ibs 158 s 164 cwt 4 5 cwt sla°- * 1897 same 1'JUO... 22 s. 602 Ibs. 108 s. 133 cwt 5 8 7 cwt. super,* 1897. same 1900 Same as plot 5; ^ ton ground lime. 1897, same 1899 36s. 56s. 642 Ibs. 769 Ibs. 88s. 107s. 124 cwt. 138 cwt. "Containing 100 Ibs. phosphoric acid. The profit is estimated from the extra mutton produced over and above that on the unmanured plot. It is valued for the purpose at 3%d. per pound, live weight. Basic slag here has proved at o^ce the cheapest and most profitable form of fertilizer on pasture. Its superiority to super- phosphate (Plots 4 and 5) seem to be due to the fact that besides containing easily available phosphate it also contains free lime. Comparison of plots 5 and 8 bears this inference. The land at Cockle Park is stiff clay, and has been under pasture for over thirty years. Basic slag is purchased on its percentage of phosphate of lime. The quality varies from about 20 to 45 per cent phosphate , (equal to 9 to 21 per cent phosphoric acid). The higher grades are usually rather cheaper per unit. The unit prices of different samples may be ascertained by dividing the prices per ton by the percentages. Other things being equal, the quality which sup- plies the unit of phosphate at the lowest cost on the farm should be purchased. I devote this amount of space to basic slag be- 180 ALFALFA FARMING .IN AMERICA. cause I have seen such good effects come from its use in England, and because it did equally well on Woodland Farm. It will never perhaps be cheap enough for use west of the Allegheny Mountains, since it is all imported from England or Germany, but along the Atlantic seaboard it is now probably as cheap a source of phosphoric acid as anything known. With basic slag one gets quite a little lime free of cost, since usually there is about 55% of carbonate of lime in basic slag. It should sell for about $1 per unit; that is, a slag analyzing 18% phosphoric acid should sell for $18 per ton, when it is about as cheap as any other source of phosphorus with the lime thrown in. In England on old pastures basic slag works miracles. There with the sowing of no seeds at all clovers spring up and cover over the land, almost crowding out the grasses. The lime has sweetened the soil, the phosphorus fed it, the clovers result. Later the decay of clover leaves and stems fill the soil with available nitrogen which in turn feeds the grass. When will we learn in America to feed soils'? Oilier Sources of Phosphorus. — Prof. Alfred Vivian, of the Ohio State University, so clearly and concisely states the composition of phosphatic fer- tilizers in his admirable little book, "First Prin- ciples of Soil Fertility, ' ' that we here quote : Phosphoric acid is present in the soil in much smaller quan- tities than potash, and experience shows that it 'is much more likely to become exhausted. In fact, there are sections of the country where no other fertilizers than those furnishing phos- phoric acid are used, while these are bought in large quantities. PHOSPHORUS FOR SOILS. 181 All this class of fertilizers contains its phosphoric acid in the form of phosphates, i. e., the phosphoric acid is combined with some basic substance, which is generally lime. The phosphates may be subdivided into two general classes — the natural and the manufactured phosphates. Natural Phosphates. — There are two general sources of phos- phates— the bones of dead animals, and certain phosphate-contain- ing minerals, which will be briefly considered. Raw bone meal is made by grinding raw bones to a powder, and the finer it is the more valuable the product. This substance contains about 22 per cent of phosphoric acid and 4 per cent of nitrogen. Raw bones contain a small quantity of fat as well and, as this prevents rapid decay of the bone, the phosphoric acid and nitrogen in the meal are somewhat slowly available to the crop. Steamed Bone meal. — Most of the bone meal sold at the pres- ent time is made from bones previously steamed to remove the fat and a part of the nitrogen compounds. The fat is used in making soap and the nitrogen in glue and gelatins. Steamed bone contains from 28 to 30 per cent of phosphoric acid and about IV2 per cent of nitrogen. The steamed bones can be ground to a much finer powder, and the removal of the fat causes them to decay more rapidly, so that they must be considered a more valuable source of phosphoric acid than the raw bones. Mineral Phosphates. — In a number of places rock deposits are found that contain varying percentages of phosphate of lime. These phosphates are usually named after the place where they are obtained, as, Carolina phosphates, Florida phosphates and Tennessee phosphates. These rocks contain from 18 to 32 per cent of phosphoric acid, and differ from the bone products in that they are purely mineral substances and contain no organic matter. Ground into a fine powder, they are sometimes sold un- der the name of floats, but the rock phosphates are used only to a limited extent in the crude condition. Superphosphates or Manufactured Phosphates. — The phos- phoric acid in all of the natural phosphates described is combined with lime in a form that is extremely insoluble in water. In or- der to make the phosphate soluble it is sometimes treated with sulphuric acid, which unites with part of the lime, leaving a phosphate which contains only one-third as much lime as the natural phosphate, and which is soluble in water. The lime and sulphuric acid make a compound which is the same as that found in gypsum or land-plaster. This combination of soluble phos- phate and gypsum, made by treating the natural phosphates with acid, is called by the various names of super-phosphate, soluble 182 ALFALFA FARMING IN AMERICA. phosphate, acid phosphate or acidulated rock. For its manufac- ture the rock phosphates are generally employed, both because they are cheaper and because the organic matter in the bones interferes with the use of sufficient acid to make all the phos- phate soluble. A good sample of super-phosphate or acidulated rock contains about 16 per cent of phosphoric acid in a form that is soluble in water. Sometimes when insufficient acid has been used a part of the soluble phosphate will change into a form in- termediate in solubility between the natural phosphate and the acid phosphate, and the acid phosphate is said to have undergone reversion, and the new compound is called reverted phosphate. The latter product is supposed to be more available to the plant than the insoluble or natural phosphate, hence the soluble and reverted phosphoric acid taken together are known as the avail- able phosphoric acid. In some instances bone meal is treated with a limited amount of sulphuric acid and the product is called acidulated bone. This substance contains a much smaller proportion of its phos- phoric acid in the soluble form than does the rock superphos- phate. When soluble phosphates are added to the soil they soon combine with the mineral matter, and are converted first into the reverted phosphate, and finally into the insoluble form such as is found naturally in the soil. In this way the phosphoric acid is fixed and there is no danger of its being lost by leaching. Relative Value of Phosphate Fertilizers. — The soluble phos- phate present in the acidulated goods is generally considered the most valuable form of phosphoric acid for use as a fertilizer. At first sight it seems useless to go to the expense of making the phosphate soluble when it is again rendered insoluble by the soil before the plant can make use of it. The real object in mak- ing it soluble is to aid in its distribution in the soil. When an insoluble phosphate is applied it remains where it falls except for the slight distribution it receives by cultivation. In the case of the soluble phosphate, on the other hand, the phosphate dis- solves in the soil water and is widely distributed before it be- comes fixed by the soil. In the former case the roots must go to the phosphate while in the latter the phosphate is carried to the roots. It follows from what has been said that after the soluble phosphate is distributed throughout the soil the indi- vidual particles must be very much smaller than is the case with the insoluble phosphate. There are some soils upon which the superphosphates cannot be used without injury, usually those that are deficient in lime, the superphosphate in such cases having a tendency to make PHOSPHORUS FOR SOILS. 183 them acid. Indeed it is even asserted that soils containing an abundance of lime in the beginning may be made acid by the continued use of superphosphate if no lime is added. When the natural phosphates alone are considered there is no doubt that the preference should be given to those derived from bones. The organic matter present in the bones decays when it is incorporated with the soil, and this process doubtless causes the phosphate to become more readily available to the plant, while the rock phosphate on the contrary is very slowly decomposed. The degree of fineness to which bone meal or mineral phosphate is ground is of prime importance. Very fine bone meal is much more available than that which is coarser and is always rated at a higher price a ton. Using Floats with Manure. — The use of floats, or finely ground phosphate rock, has not met with general favor, and it probably does not give good results when used alone. Some of the earlier experiments indicate that it has practically no value as a source of phosphoric acid for the plant. Recent investigations at the Ohio and Illinois Experiment Stations show that when floats are added to farm manure it has a very high fertilizing value; in fact the increased crop production in Ohio due to adding the ground rock phosphate to the stall manure was nearly as large as that obtained from the addition of superphosphate. The acid substances produced during the decay of the manure apparently make the phosphoric acid in the rock more available, and it would seem from these experiments that the comparatively in- expensive floats might, partially at least, replace superphosphate if used in connection with the manure. Other experiments have demonstrated that good results can be obtained from the use of ground rock phosphate when plowed under with a green manure crop like clover, but that it is of very little value if used on a soil low in organic matter. In a plot experiment at the Mass- achusetts experiment station two "equal money's worth" of ground Carolina rock and superphosphates were compared. In this case the superphosphate proved superior at first, but within a few years the plot to which rock phosphate was added gave higher yields. It would seem, on the whole, that the use of floats with manure is worthy of a trial by anyone needing a phosphate fertilizer. Ohio Bulletin 134 recommends that the ground rock be used "as an absorbent in the stable, thus secur- ing an intimate mixture with the manure in its fresh condition." Raw Plwspliatic Rock for Alfalfa. — Raw rock, or floats, the natural Tennessee, South Carolina 184 ALFALFA FARMING IN AMERICA. or Florida phospliatic rock, is the basis of the fer- tilizer called acid phosphate, or acidulated bone. It is made into acidulated form by the addition of about as much sulphuric acid as is taken of finely ground rock. The raw rock contains a large amount of phos- phorus, but it is not in an available condition to be taken up by plants ; at least this is the general supposition. Experiment, however, shows that when the finely ground pliO'Sphatic rock is put in contact with decaying organic matter in the soil it does be- come available and plants feed upon it. A given amount of money will -purchase about two or three times as much phosphorus in the form of raw rock as it will purchase in the acidulated form. J. F. Jack on. his farm in eastern Virginia has given the raw rock a careful test and with very marked results. The rock was applied at varying rates, from 250 pounds per acre to 1,000 pounds per acre. Check strips where no fertilizer was applied were left. The result showed conclusively that the raw phosphate was available and where 1,000 pounds per acre was applied the result was a splen- did growth of alfalfa. Even the application of 400 pounds gave good results, though it is not probable that it would be nearly so permanent. Fully as good results were obtained with the raw rock on this par- ticular soil where a heavy growth of crimson clover had been turned down and about 1,000 pounds per acre of water-slaked lime was used, as was had from raw bone, 400 pounds, or acid phosphate, 400 pounds. PHOSPHORUS FOR SOILS. 185 It is not yet safe to say that upon all soils the result would be the same, but on this particular soil, somewhat acid, with a heavy growth of green clover turned under, there is no mistaking the great saving resulting from the use of the raw rock. Upon this same soil potash seemed to give no noticeable result, nor could be found a strip where was applied nitrate of soda at the. rate of 100 pounds per acre. It was indistinguishable, showing that the decaying crimson clover furnished all the available nitrogen needed for the growth of the little alfalfa plants. There was left one plot with no inoculation. The result was most astonishing. Where the land was inoculated -with soil evenly spread the alfalfa stood thick and strong, knee high and more. 'Where no inoculation had been applied it was thin, weak, crowded with weeds, many plants less than 2" high. Phosphates on Alfalfa. — Even on good land I have found it very profitable to sow some sort of phos- phate with new sown alfalfa. The phosphorus cer- tainly greatly stimulates the little alfalfa plants and makes them hustle to get ahead of the weeds and grass. Thus stronger stands result. Also less seed may be sown to the acre than if no phosphorus is used. The writer and his brother have used on Woodland Farm raw bone meal, acid phosphate and basic slag with about equal reults so far as the eye could see. It is our practice to put on 250 to 400 pounds per acre of 16% acid phosphate when the alfalfa is sown in soils well filled with lime. Acid 186 ALFALFA FARMING IN AMERICA. phosphate is about the most soluble of the phos- p'hatic fertilizers and thus is best for top dressing when there is abundant lime in the soil. When there is suspicion that there may not be lime enough then basic slag or bone meal should be used, unless lime also is applied. Acid phosphate dissolves away a part of the lime in the soil. That is its one bad feature. As has been stated the alfalfa meadows on Wood- land Farm get an annual dressing of phosphorus young and old alike, and this practice pays well. Fertilizer Distributer. — On Woodland Farm we own a wide and large fertilizer distributer. This machine sows a strip 8' wide and the box holds 1,000 pounds of fertilizer.' It simply sows the stuff broad- cast on the surface. There are various types of these machines. The American Seeding Machine Co., Springfield, Ohio, makes one, and another is made by the Peoria Drill and Seeder Co>., Peoria, 111. With such a machine a man can go rapidly over his old meadow, or ~sow his phosphorus over his land preparatory to seeding his alfalfa. Time is the thing hardest to command on most farms in the spring; many would fertilize their meadows if they were not otherwise too busy. With these large wide sowing machines a man can rapidly get over his fields. No one should hesitate to buy the fer- tilizer, since a dollar so invested will usually re- turn three or four in the crop of hay. Adding to Fertility. — There is here a striking thought. Since our farms east of the Missouri PHOSPHORUS FOR SOILS. 187 Eiver are nearly all of them deficient in phosphorus, if we buy it and use it on alfalfa meadows, then feed the alfalfa hay and put back the manure, we are steadily adding to our capital of fertility; not much is lost, only we sell away in the bones of our cattle, pigs and sheep a part of it and in their flesh and blood a little more. An alfalfa farm may thus become a great laboratory of fertility gathering, provided the crops are fed on the farm. When they are sold off the story is different. Row Much Phosphorus? — In England it is the custom to apply very large amounts of basic slag to their meadows and pastures far in excess of what the plants can take up, and they seem to get large profit from so doing. There is lack of careful ex- periment to show us what amounts of phosphorus will pay best sown with or on alfalfa. The require- ments of the plant, that is, the amounts actually taken away from the soil, are as follows : 1,000 Ibs. of alfalfa hay contains 5 Ibs. of phosphoric acid; 4 tons, or 8,000 Ibs., would then contain 40 Ibs. of phosphoric acid. Two hundred and fifty pounds of 16% acid phosphate would contain that amount, and should make good what was removed from the soil by the 4 tons of hay. That there should be abund- ance in supply the writer advises the use of 300 Ibs. annually of 16% acid phosphate, or propor- tional amounts of the stuff, if a different percent- age is bought. Thus if only 10% of available phos- phoric acid is present one would need to use 400 Ibs. or more. So it is cheaper and better to use only 188 ALFALFA FARMING IN AMERICA. the high grade fertilizers containing large percent- ages of available phosphoric acid. How Well Will This Pay?— In most of the east- ern United States a 16% acid phosphate can be bought for $14 to $16 per ton. Thus 250 Ibs. would cost about $2, and the labor of applying it about 30c. Thus to fertilize an acre costs less than $2.50. The yield of hay will be increased in proportion to the need of phosphorus, but on Woodland Farm it has been as much as 2 tons of hay per acre increase, and thus this additional hay cost us only $1.25 per ton. Could we have afforded to have left this land unfertilized ! The plain fact is that farming is, after all, a manufacturing proposition. The land is the fac- tory. Its fertility is the raw material. A man would be thought inconceivably foolish who would through stinginess refuse to keep his factory sup- plied with raw materials, thus letting his machinery work to only half of its capacity. The alfalfa meadow, the corn field, these plants are our ma- chines. Feed them with their required raw ma- terial. POTASH AS A FERTILIZER. Most- soils derived from granitic rocks have in them a lot of potash. Most soils in the glaciated area of eastern and central America seems to b3 quite well supplied with potash. Some sandy soils are deficient, and peaty lands, where once old pond bottoms were, are especially deficient. To grow al- falfa on peat or to grow corn there one must use potash. Testing ivitli Potash. — As a rule on ordinary up- land clays and clay loams potash seems not to be lacking. Very often where it is applied to such soils no result can be seen. It is wise for each farm- er to make test of this matter for himself. Let him procure a few hundred pounds of muriate of potash and apply it in strips over his fields, marking the ends of the strips so that he can see the result, if there is any. About 200 Ibs. per acre of muriate of potash is a moderately heavy application. Wood Ashes. — "Wood ashes may contain 8% of potash and 2% of phosphoris acid. There is also some lime in them and other minerals in small amounts. AVood ashes have an especially good ac- tion on alfalfa. It is an interesting truth that no one has yet been able to compound a fertilizer that would have the same effect as wood ashes, though the ingre- dients were so mingled that chemically the two mate- rials were nearly identical. Nature has done some- (189) 190 ALFALFA FARMING IN AMERICA. thing with wood ashes that man can not imitate very well. The writer has secured splendid results from use of wood ashes on soils that did not seem to need potas'h. I advise that all wood ashes be saved with care and whenever there is a saw mill or any other wood-burning furnace nearby the ashes should be secured and applied to alfalfa land. Wood ashes are applied in varying amounts, from 500 Ibs. to one ton per acre. PLOWING THE SOIL. Plowing is an ancient art. The height of a land's civilization is very nearly to be measured by the sort of plowing done there. What is plowing for! It turns under loose stubble, trash and vegetation, putting it down into the soil where it may decay and by its decay help set free mineral plant food. It loosens the earth to let air in and this promotes im- portant changes in the soil. It lets the water sink down into the soil, hence plowed lands are moister and will withstand drouth much longer than un- plowed lands. There are certain crops that seems to thrive on shallow plowed soils. Alfalfa, on the other hand, seems to thrive best where the land is plowed deep. In older lands than ours, where agriculture has advanced very far towards a perfect system, deep plowing is much practiced. In France some plow a foot deep and even deeper. On the Island of Guernsey men often plow a field twice, the first plowing shallow, the second one crossways and go- ing down as far as 16". On such lands alfalfa thrives especially well. In France and Algeria men plow for alfalfa full 20" deep. Why Deep Plowing Suits Alfalfa.— The reason why alfalfa likes the land plowed deep is doubtless because the letting in of air and moisture favors the life of alfalfa-promoting bacteria. These (191) 192 ALFALFA FARMING IN AMERICA. thrive especially well in soils where the air can penetrate easily. The bacteria supply alfalfa with nitrogen. Thus deep plowing is equivalent to feed- ing the alfalfa with extra nitrogen. The heaviest growth of alfalfa that I have ever seen was on the ranch in Utah where I once lived, £he plants stand- ing 48" high all over the field and very thick. The underlying soil there was of loam, interspersed with layers of loose sand and gravel, a soil that was too easily drained, not very fertile, but well filled with lime and o
