Delaware

A late number of the Delaware Republican, published at Wilmington, contains an able address to the citizens of that State, from the Delaware Anti-Slavery Society, of which the following is the closing paragrapb: "We believethat the sy stem of slavery is wrong and only wrong; from beginning to end - from base tosummit. We ask, then, for 'the opening of the prison doors to them that are bound.' 'The doing to others as we would be done unto.' If it be objected that slaves in their present condition are unfit for freedom, we answer that they will begin to be fitted for it on the day of emancipation and not before. Practice is the great teacher since no one learns well from theory alone, and the precepts of slavery being so widely different from those of freedom, they cannotbe taught together. The ignorance and deception necessary to foster the one, are uncongenial to the other. It is vain to talk about systems of mental or moral education for those in bonds. First strike off the - first cease to do evil, and we shall learn to do well. - Let none fear the consequences of emancipation. Permanent or real evil cannot come of doing right. In asking for the rights of the oppressed, we do not ask a freedom from all laws, human and Divine. Colored people will be subject to the same laws to which we all submit or suffer. "We niourn not that the man shall toil, "1 is naure's need - 'ris God'sdecree, But let the hnnd that tills the soil. Be like the wind that fans it, frf.e." Tlie slave sy.stem being the great parent of woes and villanies, manumission is clearly our first duty. We are to do right as far as we see, and all will be well. Let us close up the channels of crime and suffering, misery and woe. - Let us not be accessary to the sundering of family ties, and breaking the barriers of purity and pollution, vice and virtue. Let the sun of Freedom but dawn triumphant over our State, and the richest ilessings of life will soon abound for all. Since righteousness exaltcth a nation, and sin is a reproach to any people, nothng need be feared for either emancipaors or emancipated." - Maine Standard.The manufacture oC air-tight tin cases for preserving Job-sters, oysters, turkeys. and ai most any other article of food, is a' great business at Eastport, Me. The mode of sealing them up, after lhe air has been exhausted by an air-pump, iskepta secret - no one being adinitted to that part of the establishment. - JV. B. BulletlTU We willlet out the secret and save the se of the air-pump. The case or can ontaining the substonce to be preserved, s set in a vessel of boiling wator andmade to boil. In this state, while the sleam excludes all the air, (which an airpump could not well do,) the operator instantly closcs the orífice by soldering on a small tin button provided lor the purpose. The can is of course removed f rom the boiling water at the instant cf soldering. Where meats nre preserved, they are introduced into the cans before thè hwwHs soldered on. It is a small hole in the headwhich is finally closed while tlio coutents are boiling.
