FUBTHEK INVESTIGATIONS IN INDIA. 25 
of the white fly for transfer to Florida. It was decided to spend a 
fortnight in southern China before taking return passage, as this 
would enable the writer to gain some information on conditions in 
that little-known country. 
It was learned from Mr. Tutcher, superintendent of the Hongkong 
Botanical Garden, that oranges were grown extensively over a broad 
range of territory inland from Canton, and that a second large citrus- 
fruit region was westward of the seaport of Swatow. As Mr. Tutcher 
kindly consented to loan the services of one of his native collectors 
who was familiar with the Canton region, arrangements were begun 
for investigating that territory as soon as passports were available. 
Application for a passport into the interior was filed at Canton 
with the American consul general, who stated that it would be about 
10 days before the same could be prepared. After returning to 
4 Hongkong the writer decided to utilize the delay occasioned by the 
v passport by a trip of inspection to the Philippines, which are about 
two days by water from this British seaport. While awaiting the 
sailing of a steamer for Manila a day was spent at Macau, a Portu- 
guese settlement near Hongkong. Some orange trees infested with 
Aleyrodes citri were seen here, thus giving a new and definite record of 
J this insect in southern China. 
Manila was reached on February 28. Through the assistance of 
officials in the bureau of science a number of orange trees were found 
in this city and carefully examined. No white flies were seen. From 
information available it would seem that very few oranges are pro- 
duced in the Philippine Islands. The only localities in which citrus 
fruits are grown commercially are Santo Tomas and Tanauan, in the 
^Province of Batangas. These localities were examined, but no white 
flies could be found. 
While in the Philippines the writer was taken ill and confined to 
vthe hospital throughout the month of March. This illness came at 
a very critical period and delayed an early return to India. Hasten- 
J ing, as he did, from the hospital before having fully recovered, it 
^was nevertheless impossible to reach India until the last of April, 
when the spring season was well advanced.

Landing in Bombay on April 22, necessary paraphernalia and pro- 
" visions were at once collected and a native interpreter engaged pre- 
paratory to starting inland.

x The writer's objective point was Lahore, in the Punjab, about 
1,200 miles inland from Bombay. Previous experience had shown 
this locality to present the best field of any place in all India for
