tlie moisture and destroying the oxygen, are not expensive items — 

 the amount being stated at about six hundred dollars per year for a 

 liouse of ten thousand bushels capacity. It requires very little skill to 

 manage the house. The thermometer hanging in a window of each 

 room, and seen from the hall without opening the door to the room, 

 indicates the temperature, whilst a hydrometer similarly placed assures 

 you that the desired dryness is secured. A single room has a capacity 

 of six or eight hundred bushels. The house at Pittsburg is divided into 

 twelve rooms, and two or three weeks may be occupied in removing 

 the fruit without especial detriment to the fruit itself 



Mr. Caldwell informed me that a lady at Detroit requested the priv- 

 ilege of placing a half bushel of Bartlett pears in the fruit-house, to be 

 kept until Chi-istmas. The liberty was granted, and at Christmas they 

 were taken out perfectly sound and fresh, improved in color, and the flavor 

 as rich as though just ripened from the trees. The temperature in all 

 the rooms I visited was at 34°, and all persons interested in the houses, 

 or who had visited them and taken an interest in the fruit preserving 

 process, with whom I conversed, had perfect confidence in its success. 

 Among these people not especially interested in the houses, were Hon. 

 Wm. Stoms and Hon. Geo. Graham, President and Ex-President of 

 the Horticultural Society of Ohio, both of whom shew me great atten- 

 tion and aided me materially in my investigations." 



EXTRACT FROM REPORT OF DR. GEO. B. LORING, PRESIDENT OF 

 THE NEW ENGLAND AGRICULTURAL SOCIETY, AND HON. EDMUND 

 BURKE, FORMERLY COMMISSIONER OF PATENTS. 



" From the Buffalo house we proceeded to Cleveland and examined 

 the fruit-house and its contents in that city. There we found a variety 

 of fruits in an excellent state of preservation, such as grapes, apples and 

 lemons. The grapes were apparently as fresh as when taken from the 

 vines, retaining, all their juiciness and bloom. And in our judgment 

 the flavor was improved by the process of preserving them. 



We brought with us, to this city, specimens of the grapes and apples 

 which we found in the house at Cleveland. They are in a fresh and 

 perfect condition, and abundantly demonstrate the efliciency of the pro- 

 cess by which they have been preserved. 



It is proper to remark that the Cleveland house is one of the first con- 

 structed according to the principles of Prof Nyce's patents, and is not 

 as perfect and thorough as the houses of more recent construction."
