Of course these figures ought not be taken as absolutely accu- 

 rate, on account of the difficulty of obtaining anything approach- 

 ing accuracy. It is hard even for two people to measure a 

 biting, screaming, struggling, clawing Hawk, even under the 

 most propitious of circumstances. 



When I first disturbed my 18S9 Hawks, they were very vocif- 

 erous and screamed loudly, just as their parents often do ; but 

 when I first got my 1893 Hawks they were very quiet and 

 retiring, only peeping occasionally, and keeping their heads 

 down, and if possible under each other, or in the corner of their 

 box. They did this for several days, until they had gotten used 

 to me, and for some time later, if they were scared in any way, 

 they would turn about with their heads low down and pointed away 

 from me at the corner of their box. 



The first day I procured them I put them in a soapbox, perhaps 

 half full of hay, and placed it on a shelf in front of an open 

 window in a room in my barn. I was careful for some time 

 about their temperature, and opened or shut the window or 

 covered their box with a blanket, as the weather seemed to 

 warrant. For the first twenty-four hours they absolutely refused 

 to eat of their own accord, and I was forced to stuff their crops 

 full of raw beef, cut up for the purpose, three times a day. 

 However, on the 13th of June, the second day I had them, both 

 Bute and Topsy seemed glad, occasionally, to pick pieces of meat 

 out of my hand, though I still had to stuff Pete's crop. 



1 This table shows approximately the average growth per day of the three Hawks 

 during the time given in the first column, the measurements being taken on the last 

 day on each line. 



Pete was not averaged into the last two lines, as he was at first sickly, and slow of 

 growth, and then died. 



The sign — means less than ; and the sign -(- means more than.
