| To illustrate, consider a nest found during the incubation stage and that candling of the eggs revealed they were close to hatching. |
| First grade that can be separated by candling, corresponding to about twenty-four hours of incubation. |
| Stage of incubation was determined by candling and by flotation as calibrated for Canvasback eggs. |
| The loss in candling is generally kept account of, but is seldom charged back to the shipper. |
| This saved the wages of the egg twirlers, whose method of candling eggs, as it was called, was far less rapid than the Separator. |
| We found nests during incubation, and estimated the hatching date by candling eggs. |
