Part 34

Celery plants will begin to grow strongly in the trenches; water with liquid manure; if troubled with insects, dust with quick lime and water with salt water. Above all things be careful in drawing in the earth to keep it out from the heart of the plant, and let it be done in dry weather.

PULLING OFF POTATO BLOSSOMS.

The Boston Cultivator, speaking of this process, says: “As the qualities of the potato-ball or apple differ considerably from the root or tuber, it may be that the juices destined to nourish the balls will not, on removing the blossoms, go to increase the roots. This view is not unreasonable.”

We do not suppose the theory to be, that the sap tending to the bloom and ball returns to the root. But, simply, that there will be so much less food to be prepared, and therefore so much less exhaustion to the vegetable economy. It is well known that the filling out and ripening of seeds is eminently exhausting to the plant. It has long been the custom of florists who wish show-flowers, to refuse their bulbous plants leave to bloom for one season, plucking off the bud, that they might be so much the stronger for the next year’s blooming.

But we suppose the truth to be this. The sap is prepared in the leaf and enters the distributing vessels of the plant. It is conveyed to every organ; each part, receiving its portion, modifies it by a farther chemical action peculiar to itself. Thus in the case of an apple-tree. The elaborated sap which goes to the leaf, the alburnum, the liber, the blossom, the fruit is the same in all; but the fruit gives it a still further elaboration, by which it imparts the peculiar properties belonging to it, in distinction from the tissues; so of the bark, the blossom, etc. If, then, the seed-vessels are removed, so much less elaborated sap is consumed as they would have required; and this, or at least, portions of it, are given to the other parts of the vegetable economy.

BLADING AND TOPPING CORN.

No one performs these operations for the benefit of the ear, but to obtain fodder, and it is then justified on the ground that the corn is not harmed by it. The sap drawn from the root does not flow straight up into the ear and kernel, but into the leaves or blades. The carbonic acid of the crude sap is decomposed, oxygen is given off and carbon remains in the form of starch, sugar, gum, etc., etc., according to the nature of the plant. When sap has by exposure to light undergone this change it is said to be elaborated.

It is only now that the sap, passing from the upper side of the leaf to a set of vessels in the under side, is reconveyed to the stem, begins to descend, and is distributed to various parts of the plant, affording nourishment to all. But when the fruit of every plant is maturing, it draws to itself a large part of the prepared sap, which, when it has entered the kernel, is still farther elaborated, and made to produce the peculiar qualities of the fruit, whether corn or wheat, apple or pear. It is plain from this explanation that a plant stripped of its leaves is like a chemist robbed of his laboratory, or like a man without lungs.

If corn is needed for fodder, let it be cut close to the ground when the corn has glazed. The grain will go on ripening and be as heavy and as good as if left to stand, and the stalk will afford excellent food for cattle. Sheep are fond of corn thus cured, and will winter very well upon it. In husking out the corn, the husk should be left on the stalk for fodder.

MAPLE-SUGAR.

As most persons who have not informed themselves on the subject, imagine that we are indebted to cane-sugar for our main supply, and that maple-sugar is a petty neighborhood matter, not worth the figures employed to represent it, we propose to spend some space in stating the truth on this matter. We will exhibit, 1, the amount produced; 2, the proper way of manufacturing it; 3, the proper treatment of sugar-tree groves.

We shall confine our statistics to the most important Northern and Western States.

1. New York produces annually 10,048,109 lbs. 2. Ohio 6,363,386 “ 3. Vermont 4,647,934 “ 4. Indiana 3,727,795 “ 5. Pennsylvania 2,265,755 “ 6. New Hampshire 1,162,368 “ 7. Virginia 1,541,833 “ 8. Kentucky 1,377,835 “ 9. Michigan 1,329,784 “ --------------- Total Of nine States 22,464,799 “

Residue thus—add for Maine, Massachusetts, Connecticut, Maryland, Tennessee, Illinois, Iowa, Missouri and Wisconsin 2,030,853 “ --------------- 24,495,652 “

Something should be subtracted for beet-root and cornstalk-sugar. But on the other hand, the statistics are so much below the truth on maple-sugar, that the deficiency may be set off against beet-root and cornstalk-sugar. That the figures do not more than represent the amount of maple-sugar produced in these States may be presumed from one case. Indiana is set down at 3,727,795; but in the four counties of Washington, Warrick, Posey and Harrison, no account seems to have been taken of this article. In Marion county, four of the first sugar-making townships, Warren, Lawrence, Centre and Franklin, are not reckoned. If we suppose these four townships to average as much as the others in Marion county, they produced 77,648 lbs., and instead of putting Marion county down at 97,064 it should be 174,712 lbs. It is apparent from this case, that in Indiana the estimate is far below the truth; and if it is half as much so in the other eight States enumerated, then 22,464,799 is not more than a fair expression of the maple-sugar alone.

Lousiana is the first sugar-growing State in the Union. Her produce, by the statistics of 1840, was 119,947,720, or nearly one hundred and twenty million pounds. The States of Mississippi, Alabama, Georgia, South Carolina and Florida, together, add only 645,281 pounds more.

Cane-sugar in the United States 120,593,001 lbs. Maple “ “ “ 24,495,652 “

Thus about one-sixth of the sugar made annually in the United States is made from the maple-tree. It is to be remembered too that in Louisiana it is the staple, while at the North maple-sugar has never been manufactured with any considerable skill, or regarded as a regular crop, but only a temporary device of economy. Now it only needs to be understood that maple-sugar may be made so as to have the flavor of the best cane-sugar, and that it may, at a trifling expense, be refined to white sugar, and the manufacture of it will become more general, more skillful, and may, in a little time, entirely supersede the necessity of importing cane-sugar. Indiana stands fourth in the rank of maple-sugar making States. Her annual product is at least four million pounds, which, at six cents the pound amounts to $160,000 per annum. A little exertion would quickly run up the annual value of her home-made sugar to half a million dollars.

Maple-sugar now only brings about two-thirds the price of New Orleans. The fault is in the manufacturing of it. The saccharine principle of the cane and tree are exactly the same. If the same care were employed in their manufacture they would be indistinguishable; and maple-sugar would be as salable as New Orleans, and if afforded at a less price, might supplant it in the market. The average quantity of sugar consumed in England by each individual is about thirty pounds per annum.

MAPLE-SUGAR MAKING.—Greater care must be taken in collecting the sap. Old, and half-decayed wooden-troughs, with a liberal infusion of leaves, dirt, etc., impart great impurity to the water. Rain-water, decayed vegetable matter, etc., add chemical ingredients to the sap, troublesome to extract, and injuring the quality if not removed. The expense of clean vessels may be a little more, but with care, it could be more than made up in the quality of the sugar. Many are now using earthen-crocks. These are cheap, easily cleaned, and every way desirable, with the single exception of breakage. But if wood-troughs are used, let them be kept scrupulously clean.

The kettles should be scoured thoroughly before use, and kept constantly clean. If rusty, or foul, or coated with burnt sugar, neither the color nor flavor can be perfect. Vinegar and sand have been used by experienced sugar-makers to scour the kettles with. It is best to have, at least, three to a range.

All vegetable juices contain acids, and acids resist the process of crystallization.

Dr. J. C. Jackson directs the one-measured ounce (one-fourth of a gill) of pure lime-water to be added to every gallon of sap. This neutralizes the acid, and not only facilitates the granulation, but gives sugar in a free state, now too generally acid and deliquescent, besides being charged with salts of the oxide of iron, insomuch that it ordinarily strikes a black color with tea.

The process of making a pure white sugar is simple and unexpensive. The lime added to the sap, combining with the peculiar acid of the maple, forms a neutral salt; this salt is found to be easily soluble in alcohol. Dr. Jackson recommends the following process. Procure sheet-iron cones, with an aperture at the small end or apex—let them be coated with white-lead and boiled linseed-oil, and thoroughly dried, so that no part can come off. [We do not know why earthen cones, unglazed and painted, would not answer equally well, besides being much cheaper.] Let the sugar be put into these cones, stopping the hole in the lower end until it is entirely cool. Then remove the stopper, and pour upon the base a quantity of strong whisky or fourth-proof rum—allow this to filtrate through until the sugar is white. When the loaf is dried it will be pure white sugar, with the exception of the alcohol. To get rid of this, dissolve the sugar in pure boiling hot-water, and let it evaporate until it is dense enough to crystallize. Then put it again into the cone-moulds and let it harden. The dribblets which come away from the cone while the whisky is draining, may be used for making vinegar. It is sometimes the case that whisky would, if freely used in a sugar camp, go off in a wrong direction, benefiting neither the sugar nor the sugar-maker. If, on this account, any prefer another mode, let them make a saturated solution of loaf-sugar, and pour it in place of the whisky upon the base of the cones. Although the sugar will not be quite as white, the drainings will form an excellent molasses, whereas the drainings by the former method are good only for vinegar.

CARE OF SUGAR ORCHARDS.—It is grievous to witness the waste committed upon valuable groves of sugar-trees. If the special object was to destroy them, it could hardly be better reached than by the methods now employed. The holes are carelessly made, and often the abominable practice is seen of cutting channels in the tree with an axe. The man who will murder his trees in this tomahawk and scalping-knife manner, is just the man that Æsop meant when he made the fable of a fellow who killed his goose to get at once all the golden eggs. With good care, and allowing them occasionally a year of rest, a sugar-grove may last for centuries.

As soon as possible get your sugar-tree grove laid down to grass, clear out underbrush, thin out timber and useless trees. Trees in open land make about six pounds of sugar, and forest trees only about four pounds to the season. As the maple is peculiarly rich in potash (four-fifths of potash exported is made from sugar-maple), it is evident that it requires that substance in the soil. Upon this account we should advise a liberal use of wood-ashes upon the soil of sugar-groves.

TAPPING TREES.—Two taps are usually enough—never more than three. For though as many as twenty-four have been inserted at once without killing the tree, regard ought to be had to the use of the tree through a long series of years. At first bore about two inches; after ten or twelve days remove the tap and go one or two inches deeper. By this method more sap will be obtained than by going down to the colored wood at first. We state upon the authority of William Tripure, a Shaker of Canterbury, N. H., that about seven pounds of sugar may be made from a barrel of twenty gallons, or four pounds the tree for forest trees; and two men and one boy will tend a thousand trees, making 4,000 pounds of sugar.

We would recommend the setting of pasture-lands, and road-sides of the farm with sugar-maple trees. Their growth is rapid, and no tree combines more valuable properties. It is a beautiful shade-tree, it is excellent for fuel, it is much used for manufacturing purposes, its ashes are valuable for potash, and its sap is rich in sugar. There are twenty-seven species of the maple known, twelve of them are indigenous to this continent. All of these have a sacharine sap, but only two, to a degree sufficient for practical purposes, viz., Acer saccharinum or the common sugar-maple, and Acer nigrum or the black sugar-maple. The sap of these contains about half as much sugar as the juice of the sugar-cane. One gallon of pasture maple sap contains, on an average, 3,451 grains of sugar; and one gallon of cane juice (in Jamaica), averages 7,000 grains of sugar.
