warm summers ; indeed the northern summer is frequently hotter 

 than the southern one. A hot summer, temperature ranging from 

 80° to 100° (Fahr.), is necessary to enable the Kumquat to form 

 its growth and ripen its new wood. In winter it will bear with- 

 out injury from 10° to 15° of frost ; and perhaps even a lower tem- 

 perature than this. 



Keeping in full view the principles I have endeavoured to illus- 

 trate, and taking our lessons in cultivation from nature, there 

 ought to be no difficulty in cultivating the Kumquat in England. 

 If we wish to have it in high health and vigour, we must keep it 

 cold and rather dry in winter. During its season of growth in 

 summer it ought to have a liberal supply of water and a tempe- 

 rature of from 80° to 100° ; and this heat should be kept well up 

 even in autumn, in order that the young wood may be well 

 ripened. 



If properly cultivated, so as to be kept in high health and in- 

 duced to bear its annual crop of shining little Oranges, it would 

 make an admirable plant for table- decoration, and w r ould remain 

 covered with its fruit for several months during the dullest time 

 of the year. 



Graft on Limonia trifoliata ; do not graft on a more tender plant. 

 It does best when planted in a border ; but the Chinese can ma- 

 nage it in pots, and we may do so as well as Hoses in pots.

Much has been said, and much has been written for and against 

 orchard-houses, and the profitable culture of orchard-house trees. 



A few days ago I had the pleasure of seeing the orchard-houses 

 at the above-named establishment, the sight of which must at once 

 convince the most sceptical that orchard-houses are, after all, 

 invaluable for protecting and bringing to perfection our more 

 tender fruits. 



* When the new orchard-house at Chiswick was projected, one of the Stu- 

 dents was sent down to Mr. Pearson's to report on the method pursued in his 

 establishment. His Keport is given here as interesting in itself and showing the 

 creditable result of the system pursued at Chiswick with regard to the Students.
