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 cheaprate. 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
