INVESTIGATIONS AND COLLECTIONS. 
In 1924, a greater amount of field-work was possible than had been in 
any previous year. In February, the Herbarium Assistant was sent with 
Dr. F. W. Poxworthy upon an expedition from Kuala Lipis via the 
Sungei Merapoh into Kelantan. In March, the Director, accompanied by 
Mr. Mohamed Haniff travelled through Kedah, Province Wellesley and 
Larut collecting economic information. In April, the latter went over part 
of the ground again to glean further information. In May the Director 
and Mr. Mohamed Haniff visited successively all the inland parts of the 
State of Perak upon the same quest; and in September, the latter 
continued the work by visiting Tapah and Telok Anson. I11 October, he 
re-visited Kuala Kangsar. In June, Mr. G. A. Best was sent upon a short 
collecting trip to Bentong in Pahang. Through November and into 
December, the' Director and Mr. Mohamed Haniff visited every centre of 
importance in the State of Pahang: while over the same period a plant- 
collector was attached to Mr. C. Boden Kloss’ expedition to the islands 
of Sipora and Siberut, off western Sumatra. Two of the Agricultural 
shows held in the Peninsula were visited by the Director, two by Mr. Best 
and two by the Field Assistant, Mr. C. X. Furtado. 
The Departmental collections made in this way exceeded 3,000 numbers. 
In September, Mr. R. E. Holttum took a short holiday at Brastagi in 
Sumatra and gave the collections which he made to the Department. 
Mrs. Burk^ll also visited Brastagi in November, and made collections which 
she presented to the Department.

The gift from Mr. Matthews to the Department was a consignment 
of seed of Lecythis Ollaria, from which six seedlings have been raised. 
Mrs. Welch, a traveller through Singapore, wrote after reaching her home 
of the pleasure she had had in seeing the Gardens and sent seed of an 
Amarant which she thought would be an addition: it has done well. 
Mr. Rigby went to considerable trouble in obtaining seed of Abutilon 
Listen for the Gardens; and the plants have flowered. Dr. Vernon’s gift 
was of some beautiful specimens of certain Australian orchids. The Royal 
Botanic Gardens, Kew, supplied many showy species of garden plants. 
The Department of Agriculture of the United States supplied plants of some 
very desirable races of the Avocado pear, which unfortunately did not 
survive the post. For these gifts and others, very sincere thanks are 
returned. 
The total number of plants received was 993 in Singapore, and 425 
m Penang*; and of packets of seeds 877 in Singapore, and 169 in Penang.
