ROLLER. — This is a heavy cylindrical instrument, to 

 pass over lands, render them more compact, and answ^er 

 other useful purposes in field husbandry and gardening. 

 Many of the complaints we hear, of seeds not growdng, 

 arise from their not being rolled. Many seeds will not 

 vegetate at ail, and many others will vegetate slowly, 

 feebly, and imequally, if the ground be not rolled soon after 

 the seed is sown. " Those rollers which are cut out of 

 free-stone, bein^ heavier than wooden ones, are best to 

 smooth and harden the alleys in gardens. But wooden 

 ones answer better in tillage, when they are sufficiently 

 large. A roller for field-husbandry should be five or six 

 feet long ; so that it may perform much in a short time, 

 being drawn by a horse or yoke of oxen, for either of which 

 it may be easily harnessed. It should be made perfectly 

 round and smooth, that it may be drawn the more easily, 

 and press the ground more equally in all parts. And it 

 should be from eighteen to twenty-four inches diameter. 

 Being large, the pressure will be greater, and the surface 

 will be the more level." — Deane, 



Where there is no roller on the premises, the following 

 is recommended as a substitute : — After the seed is sown, 

 sind the ground well raked, take a board or boards, of the 

 whole length of the bed ; lay them flat on the ground ; be- 

 ginning at one edge of the bed, walk the whole length of 

 the board ; this will press the soil on the seed ; then shift 

 the board, till you have thus gone over the whole bed ; and 

 in dry weather, cover your beds, for forty-eight hours, with 

 boards laid flat on the soil, and the seeds will come up al- 

 most immediately. If no boards are at hand, tread in the 

 seed with your feet, or strike on the bed with the blad» of 

 your spade or shovel.
