THE GREAT CUTHBERT ROOKERY 81 



made its visit. This would sum up about three thousand 

 nests or six thousand birds. 



This account is a summary of my observations during 

 the time of our stay, from Tuesday to Thursday afternoons, 

 May 12 to 14. In some ways it was the most enjoyable 

 and exciting two days of my life, even though I had not yet 

 got back to full physical condition. But the mosquitoes in 

 these swamps are something dreadful. I managed to endure 

 their unceasing attacks as I photographed, but I found that

 would not take much more to make one homesick ! 



On Thursday morning the guide awoke ill with a bilious 

 attack. So I finished up my work during the morning, and 

 after dinner started back for camp. Without the guide I am
