of the same kind was subjected to a pressure equal 

 to a column of water o/tc thousand ihiriy-foiir fctit 

 high, before it broke. If this test was correctly 

 made, and I am informed some of the gentlemen 

 who superintended it were engineers, of science, 

 it seems to leave no room for doubt, that this ma- 

 terial is abundantly strong- for all practical pur- 

 poses. The manufacturers have furnished me a 

 list of prices for which they will deliver pipe al 

 their works, which is as follows: 1 inch pipe, 7 

 cents per foot; 1 1-2 inch pipe, 9 cents per foot; 2 

 inch pipe, 12 cents per foot; 2 1-2 inch pipe, 10 

 cents per foot; 3 inch pipe, 20 cents per foot; 4 

 inch pipe, 28 cents per foot; 5 inch pipe, 36 cents 

 per foot; G inch pipe, 41 cents per foot; 7 inch 

 pipe, 52 cents per foot; 8 inch pipe, 60 cents per 

 foot. 



It is scarcely necessary to advert to the durahiliti/ 

 of this pipe, as it is known to every reader that it 

 was used in many countries centuries ago, where 

 it is yet sound. I trust that in calling the atten- 

 tion of your readers to this pipe and the use I have 

 made of it, with the success attending it, the lovers 

 of pure water will give the matter due considera- 

 tion; and where it is practicable, supply themselves 

 with this indispensable article. 



Respectfully yours, &c., Dwight Jarvis.

TO MAKE GOOD MORTAR. 



Sour together a quantity of lime and clean sharp 

 sand, for two or three weeks before being used; 

 work this well and turn it aside, and as the propor- 

 tion of lime to the sand will always depend on the 

 quality of the former, all that is necessaiy, is to 

 take care (in souring), if the lime is of a rich 

 quality, to put one-third less lime into the heap 

 than it is intended to be built with; and if the lime 

 is of pure quality, say only one-fourth less. It 

 may here be ol)served that in general, lime of the 

 proper quality is best for cementing buildings. 

 When the lime which has been previously soured, 

 as before directed, is to be used in the building, or 

 otherwise, it is to be again worked carefully over, 

 and one-fourth of quick-lime added in proportions, 

 taking care never to have more in preparation tlian 

 can be used in a short time; and this quick-lime 

 should be most completely beaten and incorporated 

 with the soured lime, and it will be found to have the 

 effect of causing the old lime to set and bind in the 

 most complete manner. It will become perfectly 

 solid without the least evaporation to occasion 

 cracks, which can only ensue in consequence of 

 evaporation; and this can only happen from the 

 want of proper union between the two bodies. 

 But by mixing and beating the quick-lime with the 

 soured mortar, immediately before it is applied to 

 use, the component parts aie brought so near to 

 each other, that it is impossible either crack or flaw 

 can take place. In short, beating has the effect of 

 closing the interstices of the sand, and a small 

 quantity of lime paste is effectual in fitting and 

 holding the grains together, so as to form a plastic 

 mass, by uniting the grains of sand which other- 

 wise would not fit each other. This system will 

 apply to the lime mortar for all descriptions of 

 work, whether for building, plastering in the inside 

 or outside of houses, water cisterns, ground vaults, 

 rough castings, ccc. — Scientific American. 



DRAINING AND IRRIGATING MA- 

 CHINE. 



This machine is very favorably noticed by the 

 Charleston Courier, the editor of which says: In 

 compliance with the invitation extended by Mr. 

 Lobby, quite a number of visitors assembled yes- 

 terday, to witness this curious and successful appli- 

 cation of machinery to a purpose in which our 

 rice planters especially are deeply interested. It 

 is adapted both to draining and irrigating lands, 

 and when set in motion by a steam engine of five 

 horse power, is capable of raising from five to six 

 thousand gallons per minute, which might be 

 greatly increased by additional motive power. It 

 has been inspected by several experienced planters, 

 and been pronounced to be a most valuable agricul- 

 tural appendage, sufficiently simple to be woiked 

 by the negroes on plantations, and not liable to get 

 out of repair. The credit of this clever adaptation 

 of well known philosophical principles to the im- 

 provement of the culture of one of our great sta- 

 ples belongs to a young Charlestonian, who, to a 

 natural genius for mechanism, adds the fruits of 

 years of laborious study and practice, in his liigii 

 and honorable vocation. — Farmer and Mechatiic.

BODILY EXERCISE IN EARLY LIFE. 



To fetter the active motions of children, as soon 

 as they have acquired the use of their limbs, is a 

 barbarous opposition to nature; and to do so, un- 

 der a pretence of improving their minds and man- 

 ners, is an insult to common sense. It may, indeed, 

 be the way to tram up enervated puppets, or short- 

 lived prodigies of learning; but never to form 

 healthy, well-informed and accomplished men and 

 women. Every feeling individual must behold, 

 with much heart-felt concern, poor little puny 

 creatures, of eight, ten or twelve years of age, ex- 

 hibited by the silly parents as proficients in learn- 

 ing, or as distinguished for their proficiency in lan- 

 guages, elocution, music, drawing, or even some 

 frivolous acquirement. The strength of the mind 

 as well as of the body is exhausted, and the natur- 

 al growth of l)oth is checked by such untimely ex- 

 ertions. We are far from discouraging the early 

 introduction of youth into the sweet and even mor- 

 alizing society of the muses and the graces; but 

 we would have them pay their court also to the 

 goddess of health, and spend a considerable portion 

 of their time, during the above period at least, in 

 innocent and enlivening sports and gambols. —

A HINT TO YOUNG LADIES. 



An intelligent gentleman of fortune visited a 

 country village in Maine, not very far tVom Bangor, 

 and was hospitably entertained and lodged by a gen- 

 tleman having three daughters — two of whom in 

 rich dresses entertained tlie distinguished stranger 

 in the parlor, while one kept herself in the kitchen, 

 assisting her mother in preparing the food and set- 

 ting the table for tea; and after the supper, in doing 

 the work till it was fully completed; when slic al- 

 so joined her sisters in llic jiarlor for the remain- 

 der of the evening. The next morning the same 

 daug'.iter was rgr.in early in the kitchen, v.-h:lc ihs
