Protessor Mapes reported by Mr. Lowe. 



Professor Mapes made the following remarks: — In these days, 

 when potatoes are sold at a high price, much larger than that ob- 

 tained for wheat, and when it is well known that notwithstand- 

 ing disease and all other difficulties pertaining to the potato, that 

 still the farmer is enabled to raise at least one hundred bushels 

 or more per acre, the importance of the crop cannot be doubted. 

 English and Irish farmers could scarcely believe the fact that 

 thousands of bushels of potatoes, not of the first quality, have 

 been sold this spring in New-York at $2 and $2.25 per bushel. 

 The increased consumption may be attributed in part to the im- 

 mense number of immigrants received in our city. It will be re- 

 membered that 600,000 are said to have arrived within the last 

 twelve months, and if we estimate that each of these individuals 

 should use but five bushels of potatoes, which is a moderate esti- 

 mate — for even at the present high price they will still be used 

 by immigrants from the ease of their preparation as food — it will 

 be seen that 3.000,000 cf bushels are required, in addition to for- 

 mer crops, to supply this increased demand alone. I shall not 

 enter into any lengthy discussion relative to the potato di- 

 sease, for this has been so fully debated that the members of the 

 Club are fatigued with its consideration In proper place, there- 

 fore, after describing modes of culture, I will refer to such reme- 

 dies as are most readily applied, and as have been found to be 

 most efiective. 



Culture. — In the culture of the potato it should be borne in . 

 mind that they are tubers, that the roots which are thrown forth 

 never yield potatoes attached to themselves; the new growth al- 

 ways occurring on the stems, and hence the mode of culture 

 should be such that after the proper number of tubers have ap-
