such an error, as a {ew persona are fully informed 

 of what has previously been done in tho.we cases 

 where machines have been long employed, as in 

 cutting straw. 



For a Thrashing Machine ; Thomas Beede, 

 Sandwich, Statlbrd county. New Hampshire, 

 February 10. 



This is a cylinder and concave machine, with 

 some peculiarilies about it upon which to found 

 a claim, but not substantially different from nume- 

 rous others of the same general construction. 



For a Conking Stove; John J. Giraud, Balti- 

 more, Maryland, February 5. 



The main improveinent spoken of in the spe- 

 cification of this stove, is a box door, which is to 

 answer the purpose ol' the ordinary Dutch oven, 

 but what are the peculiarities of its construction 

 we cannot discover, as it is mentioned in the spe- 

 cification in the most general way. There is a 

 drawing, with letters on the respective parts, but 

 we find no references to thein, and most of the 

 things represented have no novelty whatever. 

 The claim is to "the door oven at the front of the 

 fire place, as well as the general combination and 

 structure of the entire instrument." The door 

 oven, which is specially claimed, is to be dispensed 

 with when the stove is used ibr warming only. 



For a Churn; John E. Thomas, Winchester, 

 Preble county, Ohio, February 12. 



The body of the churn i« to be a box, or case, 

 through which two shafts are to run, llirnished 

 with slats, or dashers, passing f)etween each oth- 

 er ; on the outer end of each shaft there is to be a 

 pinion, which is to be turned i)y a cog wheel ; nu- 

 merous examples of" this churn exist in the patent 

 office, and probably elsewhere. 



For a Horse Power; Joseph Austin, Franklin 

 county, Vermont, February 12. 



No claim is made by the patentee to the con- 

 struction of this horse power, and although such 

 an omission is sometimes to be regretted, it, m the 

 present instance, will not be produciive of the 

 slightest loss or inconvenience, a claim having 

 been made thereto more than forty-one years ago, 

 and a drawing and description of it having been 

 given in the second volume of the Repertory of 

 Arts, published in 1795. The plan is to obtain 

 power by placing the animal near the top of a 

 large, revolving drum. 



For a Washing Machine; Luther Davison, 

 Norwich, New London county, Connecticut, Feb- 

 ruary 12. 



A cylinder, the ends of which may be of wood, 

 and the barrel part of zinc, is to revolve horizon- 

 tally ; round bars of wood are to reach from head to 

 head, on its inside, standing at a small distance 

 from its periphery, and allowing a space between 

 each of them. A partition is also to extend 

 across the middle of the cylinder, formed of simi- 

 lar bars, and dividing it into two equal parts. A 

 door on the side of the cylinder allows the clothes 

 to be put into either division of it. 



"What I claim, is the arrangement of the bars 

 in said cylinder, the partition of the cylinder, and 

 the principle of washing the clothes in two separate

parts ofthe same." A prina'ple, \he discovery of 

 which will scarcely confer immortality. 



For apparatus for Drying Cotton after it has 

 been picked, ^c; John Philbrick, Wilkinson 

 county, Mississippi, February 12. (See Specifi- 

 cation.) 



For a Machine for Shelling Corn ; Ira Smith, 

 Downingtown, Chester county, Pennsylvania, 

 February 13. 



This machine does its work by means of a ver- 

 tical revolving plate, constructed in the well 

 known way of making such plates. The sup- 

 posed novelty will appear from the claim, which 

 is to "putting teeth or projections on both sides of 

 the wheel, instead of on one side, as in the common 

 method, thereliy shelling twice as fast." It so 

 happens, however, that this contrivance is old, 

 having been patented some years since, and sub- 

 sequently re-invented more than once. 



For an improvement in the IVlicat Fan ; Da- 

 vid Flanders and Calender Rathburn, Fort Co- 

 vington, Franklin county. New York, Februa- 

 ry 13. 



The general construction of this wheat fan ia 

 the same as those in common use, and al- 

 though much pains have been taken to describe 

 its individual pans, we are not told, and are una- 

 ble to discover, in what its special utility and no- 

 velty consist. 



For a Ifachine for Cutting Sausage 3 feat ; 

 Ambrose Henkel, Shenandoah count}', Virginia, 

 February 13. 



The general construction of this machine may 

 be inferred from the claim to "a cylinder with 

 knives ; secondly, their cutting between bars of 

 any kind ; and thirdly, the ireneral construction of 

 the machine." This claim is much too broad, 

 the two first items in it not being sustained by 

 their novelty, and not, therefore, sustaining the 

 third.

EXTRACT FROM A RKVIE\V OF PROFESSOR DU- 

 CATELS' LAST REPORT OF Til E G EOLOG ICAl/ 

 SURVEY OF MARY LAND. 



[In the following article is presented an abridgment 

 of the latter part of the Report. So much of the pre- 

 vious part as is connected with agriculture, was repub- 

 lished entire in the 5th No. of this volume.] 



The report appears fully to establish the exis- 

 tence of green sand of the age of the New .Jersey 

 marl, in Kent and Cecil counties, nntl intimates that 

 ftome of the members of" the same fbiiiuition liave 

 been discovered in the Potomac counties. 



In the belief that the legislature which ordered 

 the surve) designed it as the means for develojang 

 all the advantages and riches of the state, for the 

 benefit of every portion of the population, the ge- 

 ologist in prosecuting his labors, has endeavored to 

 embrace in his report every prominent consideration 

 of practical utility immediately or remotelj' appli- 

 cable to the various interests of his fellow citizens. 



In accordance with ibis understanding of his 

 duties, he has labored, and it would seem success-
