convenient places where they can be looked at frequently

It needs to be borne in mind when the work of orchard 

 heating is begun that one has something else to do after 

 the fires are started than to stand around and see the tem- 

 perature in the heated zone rise to the point of comfort, 

 while outside the frost will be forming over all. In fact, 

 when orchard heaters are started to going it will keep all 

 hands on the bounce looking after the fires, keeping them 

 shut down or opened up so as to burn all the more vigor- 

 ously. When a sudden drop in temperature does occur, 

 and the heaters have been burning for several hours, it 

 may necessitate filling the heaters while they burn. This 

 is not an easy task, and especially when the coal burners 

 are used, as it will mean that the pots must be cleaned 

 out and sometimes that the fires must be rekindled. Then, 

 after working all night with the heaters, it will be neces- 

 sary on the day following to get them all cleaned up, 

 kindled and refilled so as to be ready in case they are 

 needed the next night. This day and night work is ex- 

 hausting, and it is important that the orchardist prepare 

 before hand and get sufficient help to do the work, and 

 have the help well drilled in their work, so that the job 

 can proceed with the least amount of trouble. Just a little 

 systematizing of the procedure helps wonderfully in mak- 

 ing a success of the work.
