The above L5 14s. clear profit on the 20 rods, is at the rate of L45 12s. profit for one acre.  Now, if a small cultivator were to plant three or four acres, and get only one-half of the above profit, it would give a good return, and would be well worth the trial.

Arrowroot requires a good rich red soil, of which there is still much lying waste.  The best time for planting it is in April, but it can be planted in March, or indeed at any time after the first of the year, till May:  though if taken up and planted before Christmas, you may depend it will not come to any perfection.  Arrowroot can be planted in many ways; either in holes made with a hoe, ploughed under, or in drills like Irish potatoes.  Now the way I prefer is to prepare the land, then strike the line at two feet apart, and make holes with a pointed stick or dibble six inches apart, putting in each hole one strong plant or two small ones, then cover them up.  This is more trouble than the old way, but it gives an excellent crop.  It can also be planted like Irish potatoes in drills, two feet apart in the rows, and six inches between the plants.  It should be hand-weeded in the spring, because if it is hoed, most likely you will cut some of it off which may be springing under ground, and it will never come up so strong again.  Arrowroot requires very strong ground and plenty of manure.  Farm yard manure is the best; next to that green seaweed dripping with salt water—­this is an excellent manure, and should be dug in the ground as the arrowroot is taken up.  I have no doubt that it would be of great advantage to the planter, if he were to put a cask in a cart, fill it with salt water, and put it on the land a few weeks before it is planted.  Some people say that arrowroot does not pay so well, because it has to stay in the ground a whole year; but then if you have onions you can plant them over it, and so obtain a crop which will pay much better than the arrowroot itself.  If you have a large piece of arrowroot ground, take up one half early, and plant it out with Irish potatoes; then take up the other half later, and with the plants set out your potato ground, that is if you have taken up your potatoes; if not, plant the arrowroot between the rows, in holes; so that when you take up the potatoes, you clean the arrowroot and loosen the ground, which will give a good crop; or you can plant Indian corn very thin over the arrowroot ground (if you have nothing else), but be sure to cut it up before it ripens corn, or it will injure your arrowroot crop; or you may plant a few melon seeds over it, and you will have a fine crop of fruit.
