calculate yields per acre of starch as follows:

'lt will be seen from the table that the yield per acre of starch is considerably in favor of the sweet potato, the yield being nearly four times as much as wheat, and over twice as much as corn. There are other factors, however, that tdemand attention in the manufacture of starch besides those mentioned, and one of the most importan of these is the character of the refuse left after extracting the starch, whether it will be suitable for cattle food or not. The percentage of protein in the sweet potato is very small, thus rendering it very poor in one of the most valuable constit- uents, and making It of little value itself as food for stock; not so with corn and wheat, which con tain about five times more of this valua- ble constituent than the sweet pota- to, thus rendering their refuse val uable as cattle food. In addition, it 1 is probable that it is with the sweet potato as it is with the potato Qrish), that the nitrogen it contains is in a great part in the amide form, which has only about one-half the feeding value of the albumino:ds.
 h letter to tho Charlest ton News and Courier, discussing the factory project, the following points were made:
 "The price which is proposed now to be paid by the factory ln twenty cents per bushel. Now, can the farmers do it? It would be well for you to get some practical farmer, one who works and fertiiz's IS well, to make calculation of the cost of an acre of cotton, and one of sweet potatoes.
 Let us just now only take for example an acre of ground which will make bale of cotton. This bale of cotton let us put at $25, and irst now that will include value of lint and seed.
 Now, how many bushels of pota toes can be made on an acre of sim liar ground; 200 bushels-$40; 300 bushels $60; 400 bushels-$sO?
 "Now, on an acre of ground so fertilized and cultivated as to make a bale of cotton, 400 bushels of Southern Queen sweet potatoes can be raised. Of course, all land will not make that many, neither will all lac d make a bale of cotton or yellow wrapper tobacco, or thirty bushels of wheat, but it will do for calculating comparative cost and proceeds. In this calculation one must take into consideration the danger to any crop from the ele- ments, except potatoes.
 "Hal can't hurt them, wind can't, storms of rain cannot, earthquakes will only loosen the soil So they can grow bigger. Now, it has been de termined that the most prolific var ieties are the best adapted to the purpose-a wonderful providence, indeed. 1t will take from 800 to 1000 bushels per day t9 run fac tory. A small factory to use 800 bushels per day will cost about $8,000; to use 2,000, about $25, 900. To run four months, daily capacity 800 bushels, will take 300 acres, mak. ing 200 bushels per acre; 15O acres, making 400 bushels. A frst--class ginnery will cost g, 300.
 "Yet many individual men buy and operate such and count themselves lucky to make it pay for itself in two or three years,
 "Why could not some of the large farmers own and operate some of these small factories? If net strong enough individually, then several together. There are capitalists now ready to meet the farmer half way Indeed, it may be possible to get the factory people to come, without any local capital invested, if the farNe- will only guarantee the crop, and that is W hat this writer wants you to bring out; get farmers to figure on cost of production, and say whether they can do it, and then they can be introduced to the fac tory people.
 "This question of supply is the l biggest one just now. As it is an
