allowed free access to salt, they will never be subject 

 to the disease called the " rot." 



Wooden posts or stakes driven under salt vats, 

 owing to the preserving quality of the salt, are prac- 

 tically indestructible. It would be very easy to 

 adapt this hint to the preservation of fence, garden 

 posts, &c., as they do in Syracuse. 



The clastic force of steam is the moving agent of 

 the machinery attached to an engine ; and therefore, 

 to keep the velocity constant, the supply of steam 

 must be regulated to the resistance to be overcome. 



Twenty-seven inches of snow give three inches of 

 water Avhcn melted, and the water thus obtained is 

 found to contain ammonia, which is the cause of its 

 great softness. 



A large species of the star-fish possesses the power 

 of breaking itself into fragments under the influence 

 of terror, rage, or despair. 



"When we look at the moon through a telescope 

 which magnifies two hundred times, we behold the 

 objects on its lunar surface in the same manner as if 

 we were standing at a point 238,800 miles from the 

 earth, in the direction of the moon, or only 1200 

 miles from that orb, reckoning its distance to be 

 240,000 miles. 



A cement composed of four parts of pure chalk, 

 and five and one half parts of fresh blue alluvial 

 clay, will be found cheaper than any other as an 

 hydraulic mortar. 



A vessel, moving through the water, commimicates 

 a motion to the same, and this quantity of motion is 

 equal to that which is lost by the moving vessel. — 

 Cktiiadian Agriculturist. 



It is observed, that the most censorious are gen- 

 erally the least judicious, who, having nothing to 

 recommend themselves, will be finding fault with 

 others. No man envies the merit of another who has 

 enough of his own. 



NOTICES OF PUBLICATIONS. 



Lectures on the General Relations which Science 

 bears to Practical Agriculture, delivered before 

 the New York State Agricultural Society, by 

 James F. W. Johnston, F. K. S., &c., &c. New 

 York: C. M. Saxton, 123 Fulton St. 

 Prof. Johnston is among the ablest writers on the 

 science of agriculture, and his works are justly noted 

 for their practical bearing ; therefore they rank high 

 in point of utility, and are among the most interest- 

 ing and instructive works extant, on agricultural 

 science. 



IIovey's Magazine op Horticulture. —This work, 

 which has been recently reduced to $2 per annum, 

 sustains a high rank, particularly in pomology and 

 floriculture. 



Downing's Horticulturist is a very interesting 

 ■work. Besides the various subjects of horticulture, it 

 is a work of fine taste on the subjects of rural archi- 

 tecture, which is attracting much attention. Joseph

ACKNOWLEDGMENTS. 



Of Calvin Haskell, Harvard, specimens of the 

 Spice Sweeting, a large and beautiful apple, of ex- 

 cellent quality. It is so much like the Hubbardston 

 Nonsuch in size, form, and color, that it would be 

 difficult to distinguish them, as to appearance, were 

 it not for the russety patch that occasionally appears 

 as a prominent mark on the Nonsuch. 



There are several other varieties of apple under 

 the name of Spice Sweeting. The most prominent 

 kind in this section is an early variety, that origi- 

 nated on the farm of Jacob Deane, Mansfield, and it 

 has often been seen at the exhibitions of the Mass. 

 Horticultural Society. As this has been long known 

 to the public, we think it should be regarded as the 

 true, and entitled to the name exclusively. See 

 American Fruit-Eook. 



From E. \V. Bull, Concord, a lot of fine seedlinj^ 

 grapes, which he produced by a cross of the Ca- 

 tawba with a native grape. It is very good, and 

 partakes of the nature of its parents, ha^-ing some of 

 the vinous flavor of the Catawba, and a little of the 

 acid peculiar to our native fruit. This is not a good 

 season for testing grapes, as but very few come to 

 perfection, owing to the coldness of the season, and 

 a blast on the leaves. The bunches and berries of 

 this grape are large, and Mr. Bull remarks that it is 

 productive, perfectly hardy, and that it generally 

 ripens early in September. 



From Moody Ordway, of the Gannsou nursery, 

 West Newbury, a box containing a variety of excel- 

 lent apples and pears. Among the most prominent 

 is the Hock Sweeting, an apple of a liigh character, 

 both for the dessert and for baking. It is very ten- 

 der and rich. The size is medium ; form flattish ; 

 and the color is nearly all a beautiful red. It is 

 doubtless one of the finest of sweet apples. In use 

 from the middle of August to November. It origi- 

 nated on the farm of the late Elihu Pearson, Esq., 

 "Byfield Mills," Newbury. It came up lictwccn two 

 rocks ; hence its name. We liave growing another 

 Rock Sweeting, from Cajit. Silas Allen, Shrewsbury, 

 which is a late winter and spring fruit. Wo know 

 not for which variety the name may be claimed by 

 right of priority. The same name for several fruits 

 produces confusion in the pomologieal nomenclature,
