ON THE CULTURE 



stove. Running round the bark-pit is generally 

 deemed the most convenient. To these horizontal 

 pipes must be affixed a few perpendicular ones of 

 yet smaller dimensions ; each of which must have 

 a plug. 



When steaming is required, you heat the boiler 

 in the shed behind the stove ; then take out 

 the plugs from the perpendicular tubes, and you 

 steam the stove in a few minutes to any degree 

 required. 



It may be necessary to remark, that great care 

 should be had in supplying the boiler with water ; 

 because, if permitted to boil dry, it would en- 

 danger its breaking by having cold water put into 

 it while it remains in a hot state. 



On the Covering of the Hot-house. 



The covering of the glasses in a hot-house is 

 not absolutely necessary, even in our severest 

 seasons: yet where the whole of the glasses are 

 covered during the winter nights, much less fuel 

 is required than in other hot-houses where there 

 is no such convenience : however, the saving in 

 fuel is far from being adequate to the expense at- 

 tending the covering; for, besides the first expense 

 of the covers, and the daily one in putting them 

 on and taking them off during the winter season, 

 we find, by experience, that more glass is broken 

 thereby than by every other accident. But here 

 it may be said, that glass is also frequently broken
