In compliance Avith your request, the following notes on miscellaneous horti- 

 cultural operations have been prepared as an exposition of the practice pursued 

 in the garden of the department : 



ORCHARD HOUSES. 



A small orchard house has been erected and put in operation for the double 

 purposes of presenting an example of a cheap plant structure, and to illustrate 

 the method of fruit culture by restricting root-growth. 



The orchard house is comparatively a new feature among horticultural struc- 

 tures. It is simply a miniature orchard under glass. At first sight such an 

 arrangement would seem altogether superfluous, as our climate is so favorable 

 to fruit-growing ; but while this is perhaps true in a general sense, we find, on 

 looking closely into the particulars, that many portions of the country are not 

 so favorably situated in this respect as others, as, of course, might be expected 

 where the climate ranges from a frigid to a torrid zone. Then, again, the injury 

 resulting from insects, from early and late frosts, from extremes of temperature, 

 from blight, mildew, rot, and other casualties, all combine in completing a 

 formidable phalanx of difficulties, too familiar to fruit-growers. 



The genial modified temperature of the orchard house exempts the inmates 

 from the injury resulting from sudden and extreme changes and their concomi- 

 tant evils, while the insect family, so destructive to our fields and orchards, can 

 readily be destroyed or excluded. 



While these advantages are in themselves of importance, yet they are only 

 incidental and consequent upon a principle in plant-growth which is entirely 

 under control in house culture. This principle is clearly stated by Lindley in 

 the following sentences : 



"Whatever produces excessive vigor in plants is favorable to the production of leaf buds, 

 nua unfavorable to the production of flower buds ; while, on the other band, such circum- 

 stances as tend to diminish luxuriance and to check rapid vegetation, without affecting 

 the health of the individual, are more favorable to the production of flower buds than of 

 leaf buds."
