Dr. A. rather iudiiied to the opinion that tl^e appearance of 

 the egg and the caterpillar, were the results of the disease rather 

 than the cause. While the root was decayed, the stem above was 

 healthy ; the disease could not have descended from the stalk, nor 

 have been produced by the caterpillar. ' 



Professor Mapes mentioned the valuable experiments on potato 

 culture made in St. Helena, by Beatsou. He planted them at va- 

 rio.us depths, and various assorted sizes. . The largest potatoes 

 gave the largest crop, and those planted at six inches depth did 

 best. A German mode is to bury the stalk all but its top. 

 When the stalk is twelve inches long, and as. it grows, continue 

 to bury it in the same manner until it blossom.s. They got a 

 hundred times as many tubers, but these were of the size of peas 

 and grapes. ' 



We occasionally find the whole potato which we had planted 

 still whole, after producing its crop. It is, 'however, greatly 

 changed. It is now hard and heavy, but, on examination, we 

 find it watery, and that all the starch that was in it when plant- 

 ed, has gone into the new tubers. Mr. Pell, of .Pelham, scoops 

 out an eye of a potato with a small guage, and plants that, the 

 piece of potato about the eye being about half an inch in diame- 

 ter. * I tried this, and got less weight in the crop. My plan now 

 is to plant potatoes six inches deep, and cultivate . them flat; no. 

 hills. I have tried tilling the soil well, making the surface 

 smooth, laying the potatoes on the surface and covering them 

 entirely with six inches depth of salt hay. They yielded well, 

 but whenever the sun reached any of them, it. made them green, 

 and very bitter. When potatoes are exposed so, this occurs even 

 on the uppermost potatoes in an open barrel. The potato malady 

 has lessoned in the last two years. 



Professor Harris, is his valuable entomological Work, says that 

 no insect theory (in this case) is right. 



Colonel Houghton wished to state a singular fact with regard 

 to locusts. Some seven or eight years ago I observed the dry rot
