The Connecticut Agricultural Experiment Station was established in ac- cordance with an Act of the General Assembly, approved March 21, 1877, "for the purpose of promoting Agriculture by scientific investigation and experiment." The Station is prepared to analyze and test fertilizers, cattle-foods, seeds, soils, water, milk, and other agricultural materials and products, to identify grasses, weeds, and useful or injurious insects, and to give information on the various sub- jects of Agricultural Science, to the Citizens of Connecticut. The Station makes analyses of Fertilizers, Seed-Tests. &c, for the*Citizens of Connecticut without charge, provided: 1. That the results are of use to the public and are free to publish. 2. That the samples are taken by consumers from stock now in the market, and in accordance with the Station instructions for sampling. 3. That the samples are fully described on the Station "Forms for Description," or otherwise as may be required. All other work proper to the Experiment Station that can be used for the pub- lic benefit will be made without charge. Work done for the use of individuals will be charged for at moderate rates. The Station will undertake no work, the results of which are not at its disposal to use or publish, if deemed advisable. Results that are of general interest will be published in Bulletins (of which copies are sent to each Post Office in this State, addressed to the Postmaster), and will be summed up in the Annual Reports made to the Legislature. Every Connecticut citizen who is concerned in agriculture, has the right to apply to the Station for any assistance that comes within its province to render, and the Station will respond to all applications as far as lies in its power. flgP^ Instructions and Forms for taking samples, and Terms for testing Fertil- izers, Seeds, etc., for private parties, sent on application. $W Station Grounds, Laboratory and Office are on Suburban St., in the city of New Haven, between "Whitney Avenue and Prospect St., If miles North of City Hall. Suburban St. may be reached by Whitney Lake Horse Cars, which leave corner of Chapel and Church Sts. each hour and half hour. Return cars may be taken by leaving the Station on the hour or half hour. D^" The Station and Director's house (54 Trumbull St., near Whitney Avenue^ have Telephone connection and may be spoken from the Central Telephone Office 346 State St., or from Peck & Bishop's Office in Union R. R. Depot, New Haven, and from other Telephone Offices. Parcels by Express, to receive attention, should be prepaid, and all com- munications should be directed, not to individual officers, but simply to the Agricultural Experiment Station, New Haven, Conn. BULLETIN No. 73. April, 1883. AN ACT CONCERNING COMMERCIAL FERTILIZERS. General Assembly, January Session, A. D. 1882. Be it enacted by the Senate and House of Representatives in General Assembly convened: Section 1, Every person or company who shall sell, offer, or expose for sale, in this State, any commercial fertilizer or manure the retail price of which is ten dollars, or more than ten dollars per ton, shall affix conspicuously to every package thereof a plainly printed statement clearly and truly certifying the number of net pounds of fertilizer in the package, the name, brand, or trade-mark under which the fertilizer is sold, the name and ad- dress of the manufacturer, the place of manufacture and the chemical composition of the fertilizer, expressed in the terms and manner approved and currently employed by the Connecticut Agricultural Experiment Station.* If any such fertilizer be sold in bulk, such printed statement shall accompany and go with every lot and parcel sold, offered, or exposed for sale. * A statement of the per cents: of Mtrogen, Phosphoric Acid (P 2 5 ) and Potash (K 2 0), and of their several states or forms, will suffice in most cases. Other in- gredients may be named if desired. In all cases the per cent, of nitrogen must be stated. Ammonia may also be given when actually present in ammonia-salts, and "ammonia equivalent to nitro- gen" may likewise be stated. The per cent, of soluble and reverted phosphoric acid may be given separately or together, and the term "available" may be used in addition to, but not instead of soluble and reverted. Insoluble phosphoric acid may be stated or omitted. In case of Bone, Fish, Tankage, Dried Meat, Dried Blood, etc., the chemical composition may take account of the two ingredients: Nitrogen, Phosphoric acid. For Potash Salts give always the per cent, of Potash (potassium oxide) ; that of Sulphate of potash or Muriate of potash may also be stated. The chemical composition of other fertilizers may be given as found in the Station Reports. Sec. 2. Before any commercial fertilizer, the retail price of which is ten dollars, or more than ten dollars per ton, is sold, offered, or exposed for sale, the manufacturer, importer, or party who causes it to be sold, or offered for sale, within the State of Connecticut, shall file with the director of the Connecticut Agri- cultural Experiment Station two certified copies of the statement named in section one of this act, and shall deposit with said director a sealed glass jar or bottle containing not less than one pound of the fertilizer, accompanied by an affidavit that it is a fair average sample thereof.* Sec. 3. The manufacturer, importer, agent, or seller of any commercial fertilizer, the retail price of which is ten dollars or more than ten dollars per ton, shall pay on or before the first of May, annually, to the director of the Connecticut Agricultural Experiment Station, an analysis fee of ten dollars for each of the fertilizing ingredientsf contained or claimed to exist in said fertil- izer: provided, that whenever the manufacturer or importer shall have paid the fee herein required for any persons acting as agents or sellers for such manufacturer or importer, such agents or sellers shall not be required to pay the fee named in this section. Sec. 4. Every person in this State who sells, or acts as local agent for the sale of any commercial fertilizer of whatever kind or price, shall annually, or at the time of becoming such seller or agent, report to the director of the Connecticut Agricultural Experiment Station his name, residence, and post-office address, and the name and brand of said fertilizer, with the name and address of the manufacturer, importer, or party from whom such fertilizer was obtained, and shall, on demand of the director of the Connecticut Agricultural Experiment Station, deliver to said director a sample suitable for analysis of any such fertilizer or manure then and there sold or offered for sale by said seller or agent. \ * The analysis of samples sent in accordance with section two is discretionary with the Station. Such samples are intended for preservation as manufacturers' standards. f The Station understands " the fertilizing ingredients" to be those whose determination in an analysis is necessary for a valuation, viz: Nitrogen, Phos- phoric acid and Potash. The analysis-fees in case of any fertilizer will therefore be ten, twenty or thirty dollars, according as one. two or three of these ingredients are contained or claimed to exist in the fertilizer. On receipt of statements, samples and analysis-fees, the Station will issue Certificates of compliance with the law. X Blanks for Dealers' Reports will be mailed to applicants. Sec. 5. No person or party shall sell, ofier, or expose for sale, in the State of Connecticut, any pulverized leather, raw, steamed roasted, or in any form, as a fertilizer or as an ingredient of any fertilizer or manure, without explicit printed certificate of the fact, such certificate to be conspicuously affixed to every package of such fertilizer or manure, and to accompany and go with every parcel or lot of the same. Sec. 6. Every manufacturer of fish guano, or fertilizer of which the principal ingredient is fish or fish-mass from which the oil has been extracted, shall, before manufacturing or heating the same, and within thirty-six hours from the time such fish or mass has been delivered to him, treat the same with sulphuric acid or other chemical, approved by the director of said experiment station, in such quantity as to arrest decomposition: provided^ however, that in lieu of such treatment such manufacturers may provide a means for consuming all smoke and vapors arising from such fertilizers during the process of manufacture. Sec. 1. Any person violating any provision of the foregoing sections of this act shall be fined one hundred dollars for the first offense, and two hundred dollars for each subsequent violation. Sec. 8. This act shall not affect parties manufacturing, import- ing, or purchasing fertilizers for their own private use, and not to sell in this State. Sec. 9. The director of the Connecticut Agricultural Experi- ment Station shall pay the analysis-fees received by him into the treasury of the station, and shall cause one or more analysis of each fertilizer to be made and published annually. Said director is hereby authorized, in person or by deputy, to take samples for analysis from any lot or package of manure or fertilizer which may be in the possession of any dealer. * Sec. 10. The director of the Connecticut Agricultural Station shall, from time to time, as bulletins of said station may be issued, mail or cause to be mailed two copies, at least, of such bulletins to each post-office in the State.* Sec. 11. Title sixteen, chapter fifteen, sections fifteen and sixteen, and title twenty, chapter twelve, section five of the general stat- utes, and chapter one hundred and twenty of the public acts of 1881, being an act concerning commercial fertilizers, are hereby repealed. Sec. 12. This act shall take effect on the first day of Septem- ber, 1882. * The Station will hereafter mail a package of its Bulletins to each postmaster in Connecticut, and will send, up to reasonable limits, as many copies as it may- receive notice are desired.

For 1883 the following revised Trade Values will be employed in Massachusetts, New Jersey and Connecticut, for comparing Fertilizers. The values are deduced from the ruling market rates of the six months ending March 1, 1883, and are mostly the average wholesale prices for that period, plus 20 per cent. They signify cash, delivered free on board (f. o. b.) at point of shipment. Due allowance must be made for transportation and long credits, as well as for the fluctuations of the market, which cannot be foreseen. The values used during 1881 aud 1882 are given for comparison. 1881. 1882. 1883. , Cents per lb. , Nitrogen in nitrates,... 26 26 20 " in ammonia salts, -. 22$ 29 26 " in Peruvian Guano, fine steamed bone, dried and fiDe ground blood, meat and fish, superphosphates and special manures, 20 24 23 " in coarse or moist blood, meat or tankage, in cotton seed, linseed and Castor Pomace, _ 16 " in fine ground bone, horn and wool dust, 15 " in fine medium bone, 14 " in medium bone, 13 " id coarse medium bone, 12 " in coarse bone, horn shavings, hair and fish scrap, 11 Phosphoric acid soluble in water, 12$ " reverted" and in Peruvian G-uano, 9 insoluble, in fine bone, fish guano and super- phosphates, 6 insoluble, in fine medium bone, 5$ " in medium bone, 5 " in coarse medium bone, . . 4$ " in coarse bone, bone ash and bone black, 4 insoluble, in fine ground rock phosphate, 3| Potash in high grade sulphate, 7$ " in low grade sulphate and kainite, i — 5$ " iu muriate or potassium chloride, 4$ 18 18 11 17 15 15 14 14 13 13 11 11 12$ 11 9 8. 6 6 5$ 5$ 5 5 4$ 4$ 4 4 3 2f 7 7 5 4$ 5 4$ University of Connecticut Libraries 39153029145689
