tion with water. Three tablespoons full of the cresol soap to 

 €ach gallon of water will make a satisfactory solution. This 

 solution may be applied through any kind of spray pump or 

 with a brush. Being a clear watery fluid it can be used in any 

 spray pump without difficulty. For disinfecting brooders or 

 incubators which there is reason to believe have been particu- 

 larly liable to infection with the germs of white diarrhea or 

 other diseases the cresol may be used in double the strength 

 given above and applied with a scrub brush in addition to the 

 spray. 



The first consideration in choosing a disinfectant must be its 

 effectiveness. It is a poor sort of economy to use a disinfectant 

 which costs little and will kill few or no germs. Taking 

 into account its effectiveness in dilute solutions liquor 

 cresolis compositus is believed to be one of the best and cheap- 

 est germicides and disinfectants available. The Station is using 

 it altogether in its own work, and feels justified in recommend- 

 ing it to poultrymen. 



EGG RECORD SHEETS. 



The purpose of using trap nests is to obtain records of the 

 performance of individual hens. The records obtained from 

 such work only attain their highest value if they are kept in such 

 form as (i) to be easy of reference, and (2) to combine a maxi- 

 mum of detail with a minimum of space on paper. If large 

 numbers of birds are trap nested it is not feasible to use the 

 house records as the permanent records. The original records 

 made in the poultry house must be transferred to some form of 

 permanent record sheet. 



In 1908 the permanent records of egg production were trans- 

 ferred to a loose leaf system in conformity with all other records 

 taken in the poultry work.* A loose leaf record sheet (5" x 8") 

 was designed for the purpose. This sheet is shown in reduced 

 facsimile in Fig. 7. It will be observed that one sheet holds 

 the daily egg record of one bird for one year, together with a 

 considerable amount of pertinent data respecting the egg pro- 

 duction of her ancestors, and her own tgg production after the 

 pullet year. Spaces are provided for totals and sub-totals at the 

 risfht hand side of the sheet.
