tommon prices. A root will often give thirty eyes. These young 

 Foots raised in cold frames, are more perfect than the cut or divided 

 roots of old plants, and produce better results. It is true that 

 the seeds of the best rhubarb, say Myatt's Linnseus and the Vic- 

 toria, will give two kinds, the smaller of which is so much earlier ,- 

 as to be more valuable, from the higher price of the product early 

 In the season. 



H. C. Vail. — I would state that many farmers occupying the 

 light sandy soils of Long Island, and Monmouth Co., New^ Jersey, 

 ire in the habit of throwing up ridges from nine to twelve inches 

 high, running east and west, thus protecting the south side from 

 the cold northern winds. Cabbage, and other plants, are set on 

 the warm side of the ridges, and protected by a mulch of salt 

 hay, straw, or other refuse litter. Even without making ridges, 

 and by the use of the mulch alone, plants are started in Septem- 

 ber, kept through winter, and commence growing in early spring. 

 This plan may, and probably will, be adopted by many who can- 

 aot afford to construct regular cold frames. 



VENTILATION OF STABLES. 



Prof. Mapes. — There are a few features connected with the ven- 

 tilation of stables, which are very important. 



In the first place, we all know that the process of digestion is 

 but a slow process of combustion, and the same thing takes place 

 in the stomach of the animal, but progresses more slowly than in 

 a stove. It must be evident, therefore, that if a stable be too cold, 

 A larger amount of food will be consumed by animals to produce 

 the necessary amount of heat, nor can you produce excessive heat 

 and at the same time obtain a large amount of flesh; therefore^ & 

 stable of the right temperature, will enable you to winter your 

 cattle at a less expense, from their consuming a less amount of 

 food. 



Now as to the necessity of ventilation apart from warming. 

 We are all aware that a man renders twelve gallons of air per 

 minute incapable of sustaining life, for the products of decom- 

 position during this space of time, will surcharge the air irith too
