AMERICRN INSTITUTE. 1*75 



The Washingtonia has, in California, attained the height of upwards of 

 three hundred feet, with a diameter of about thirty feet, at an age judged 

 to be some three thousand years. This great American tree has been 

 named Sequoia by some, Wellingtonia by others ; but v/e determine to call 

 it by a greater name than any of 3,000 years — the name of our George 

 Washington. 



We wish to preserve a record of the few remaining in California — fear- 

 ing that they may by some misfortune be lost ; and they cannot again grow 

 in less than probably 2,000 or o,000 years. 



The grove in Mariposa, contains 427 trees in a space three-fourths of a 

 mile long, and one and a half mile wide. Their sizes now, are as follows : 



One 34 feet diameter ; two 33 feet diameter ; thirteen 25 to 30 feet di- 

 ameter ; thirty-six 20 to 25 feet diameter ; eighty-two 15 to 20 feet diame- 

 ter. One tree has fVillen, which measures nearly 40 feet in diameter, and 

 400 feet in length. 



There are but five groves of these trees known, containing altogether but 

 less than 800 trees — all growing between latitude 27 deg. 40 min. and 38 

 deg. 15 min. north. The Toulumnc grove contains only ten trees, one or 

 two of which are, it is said, 35 feet in diameter.

We take great pleasure in extracting from the works of this great so- 

 ciety. 



OBSERVATIONS ON THE RECENTLY INTRODUCED MANU- 

 FACTURED FOODS FOR AGRICULTURAL STOCK. 



By J. B. LaweSy F. R. S. 

 I have, as others have, employed the manufactured foods on my farm. 

 The average prices of the following stock foods for the six weeks ending 

 July 17, 1858, were as follows : 



1 cwt. of Barley, 8.6 



do Oats, 9.2 



do Beans, 9.4 



do Peas, 9.6 



do Lentils, 10.0 



do Oilcake, 10.0 



do Linseed cake, 16.6 



do Hay, 4.0 



Thus the manufactured foods cost, weight for weight, four or five times 

 as much as the nutritive of the ordinary stock foods on our farms. Very 

 undeniable evidence of their superiority should therefore be required to in- 

 duce the farmer extensively to employ them. But it is strange that among 

 the numerous testimonials, in general terms, no evidence based upon exact 

 comparative experiment, showing actual weights of food consumed, and the 

 increase in live weights obtained, has been brought forward in favor of
