AMERICAN INSTITUTE. 201 



my experience has taught me. In April 1855, I planted four 

 bulbilles, (little balls,) of this year. On tlie Ctli of November 

 last, I gathered four tubers about 18 or 20 inches long, I planted 

 one in a pot of proper depth and buried pot and all in the earth 

 just below tlie surface. I flattered myself that I should demon- 

 strate its ability to resist frost. But, on the 9th of March last, I 

 examined my Yam and found the top rotten ; I turned it all out 

 of the ground, and found it rotten two thirds down from its top; 

 the lower one third sound. The ground had frozen to that depth. 

 The thermometer (Centigrade,) marking 12'^ to l'3° below zero, 

 (ze.) by Fahrenheit + 8*^. It therefore seems to me that this 

 Dioscorea batatas will not survive frost of severity. 



There is apparently a contradiction between my experiment 

 and that of the Museum. But although their Yams sprouted and 

 grew in the spring of 1855, it only proves that (like mine,) the 

 roots did not all rot — neither did mine. So the common potato 

 is safe in the ground where it grew, all winter, if not reached by 

 frost. 



TRANSPLANTING EYER-GREENS. 



We take pleasure in extracting the following from the National 

 Intelligencer of May 17th, 185(3. 



For although it is true that some understand how to do it, yet 

 as in thousands of other things the many do pot. For Ave see 

 almost everywhere the transplanted evergreensturned even brown, 

 they are dead : 



" Strange as it may seem to most people, about the 4th of July 

 is the proper time to transplant ever greens, but it can be done 

 in June, or any time in July. I have transplanted hundreds as 

 late as the first of August, vrith perfect success. 



At any other season of the year it is very difficult to make 

 them live, and it is accounted for by the fact that the sap does 

 not run at the same time with deciduous trees, (those that lose 

 their leaves every year.) Most people imagine that they require 

 a great deal of water, and often kill them by hydropathy. The 

 roots of the evergreen in its natural state, are sheltered from the 

 rain and sun by their foliage, which makes an umbrella over 

 them, and they will flourish we all know on rocks where no 

 other trees will live. 



The earth should have a good soaking at the time of trans- 

 planting, but do not Avater the tree again (unless the weather 

 should be very hot and dry) for ten or twelve days, then a good • 

 drenching is all they require."
