The latter has oftencaused the total loss of a crop, the blossomsdropping prematurely after the house has beenkept close and too warm by fire-heat at night.It is not, however, absolutely necessary thatthe temperature should be so low as 34c, al-though that will not do harm, except in retard-ing the process. As time is an important objectin forcing, it is desirable, where fuel can beafforded, that as much heat be applied as canbe done with perfect safety, both as regardsthe health of the tree and the security of thecrop. It has been proved that 50° is a safe 184 THE GAEDENEES ASSISTANT. temperature while flowering, and we wouldtherefore recommend it. Through the day the temperature may beallowed to rise by sun-heat to 60° or 65°, withplenty of air; but any sudden influx of cold aircausing a lowering of the thermometer shouldbe avoided. Air must be given to prevent the

Independent of sun-heat the range oftemperature between the minimum at night,and maximum by day, may be 5°. For ex-ample, if at a certain stage of growth (as whenthe trees are in flower) the maximum tempera-ture with sun-heat in January is 65°, and theminimum temperature at night is 50°, a littleair should be given at the top when the ther-mometer rises to 53°, to be increased when ithas risen 5° more, and a chink of front airshould be put on when it reaches 60°, and in-creased afterwards if the temperature is likelyto rise above 65°. After the blossoms drop, the condition of theexpanding foliage should be watched, and if itbe tender compared with that in a similar stageon Peach-trees on the open wall, less heat andmore air must be given, till by a slower growththe proper firmness of texture is produced.
