and the soil can then be renewed or meliorated on the dif- 

 ferent sides at successive periods. Of late, such tubs have 

 been constructed of large slates ; these have an elegant 

 appearance, and they are equally convenient, the sides 

 being removable as in the wooden structures. At some 

 places, the orange-trees are planted in conservatories 

 erected for the purpose. In the neighborhood of Paris, 

 the orangeries are little better than dark sheds, in which 

 the trees are kept protected during the winter months, light 

 and air being given only when the weather permits. At 

 Woodhall, in Lanarkshire, they were trained against trel- 

 lises, under glass, and in this way produced abundant crops 

 of fine fruit. We have there seen a plant of the St. 

 Michael's orange, twenty-four feet wide and eighteen feet 

 high, clothed with fruit. 



Middle-sized plants are frequently imported trom the 

 Italian nursery gardens, and this is the readiest way of 

 procuring large specimens at a cheap rate. The plants are 

 closely packed in boxes, with some grass or moss around 

 the roots. Upon their arrival they are in a withered and 

 dead-like state, and require considerable care and manage- 

 ment to recover them from the effects of the voyage. When 

 propagated in this country, they are budded on citron or 

 Seville orange stocks; the former recommended by Miller 

 as preferable. The seeds of the stocks are sown in pots, 

 and ^the growth of the seedlings is aided, during the first 

 and second summer, by the application of slight bottom- 

 heat in a hotbed frame. These are usually budded in 

 August. The late Mr. Henderson, gardener at Woodhall, 

 used to graft his trees, employing cions formed of the wood 

 of the second year. He also propagated by cuttings, con- 

 sidering this the quickest mode of obtaining plants. We 

 may add that this most successful cultivator of the orange
