The varieties known as "Sweet," are the kinds cultivated to be used in the green state. Corn may either be planted in "hills," dropping three or four seeds in a hill four feet apart each way, or in rows five feet apart, dropping the seeds at distances of eight or ten inches in the rows. In this latitude it is useless to plant corn before the middle of May. For succession crops it should be planted every two or three weeks until July first; after that date it will not mature here. Corn requires a rich light soil to be early. The leading varieties are Dwarf Early Sugar for first early, Crosby's Early Sugar for second, and Stowell's Evergreen for main crops. Three or four quarts is required, if succession crops are sown; if only one crop, two or three pints will be sufficient.
