Lien-Cheng (25/40N - 116/140E): The pr@sence of a permanent beam
approach landing system plus sites for a mobile (Refer to
GP/I-176) approach landing system indicates this field will
have an all weather capability. The permanent beam approach
system is located at the northeast end of the runway, whereas
at the other newly constructed airfields in Southeast China
the landing systems are on the southwest ends
Lung-tien (25/35N --119/28E): The southwest third of the runway
still remained to be surfaced on photography. 25X1D
Activity at that time was very light, with little equip_ir_ent
material and personnel in the area. The heavy anti-aircraft
situation has undergone a change with two of the eight-gun
85 mm batteries empty and the other two eight--gun batteries
only occupied with four guns each.
25X1 D
Hui-an (25/02N - 118/48E): On ~`hotography twenty
four heavy anti-aircraft guns were deployed on the airfield
between the taxiway and runway in three eight-gun batteries.
Two of the batteries were accompanied by fire control equip-
ment. The two eight-gun heavy (85 mm) anti-aircraft positions,
previously reported, were unoccupied on the above date.

city. The tunnel appears in an advanced stage of construction
as indicated by extensive waste dumps near bosh ends of the tunnel.
The Chi-!-lei to Kao-Chi causeway is completed. The base of
the Kao-psu to Chi-Lei causeway (9000^ in length) has been completed
except for a 18001 segment in tre deep water channel adjacent to
Chi -Mel.
An additional 9.5 miles of survey lines on the Nan-P'_.ng to
Fu-Chou railroad line was detected on photography. 25X1D
These lines extended from Nan-Ping eastward to Chi-Chi on the
north bank of the 21in River.
Truck Activity: There were 133 trucks in the vicinity of Lien-Cheng
25X1 D AF on photography. Sixty of these were located in a
motor pool 6000 feet south of the runway. Another motor pool
containing fifty-five vehicles is located 5000 feet north of the
runway. The remainder of the trucks enumerated were scattered
about the area.
On two hundred and twenty-eight trucks were
noted in and about Chienou (27/03N - 118/19E). The majority of
these vehicles were concentrated in two motor pools.

Ate: Five new eight-gun heavy-(85 mm) anti-aircraft batteries have been
located in the Amoy area (See Enclosure 1). These locations are:
1. Ixmi diately north of ghi-lei;
2. At the site of aformer four-gun battery or. the northeast end
Df the Kao-Chi airfields
3. On a point of land near the tc n of Choi-Shang9 on Amoy Island#
4. On the site of an old four-gun position near the boat basin at
the north edge of Amoy City; and
5. On high ground one mile east of Amoy City.
Ping-Hoi (25111N - 119/16E): Recent military activity has been noted near
Ping-hoi, located on the coast approximately seven miles northwest
of Lu-tzu Island. One four-gun heavy (85 mm) anti-aireraft battery
and probably four 4-gun medium anti-aircraft batteries have been
located. In addition numerous unoccupied artillery positions were
Peiling Peninsula: Recent aerial ca erage of the peninsula indicates
that there has been no mayor changes in the military situation in
the area. Artillery positions appear to be well dug in with no
evidence of shifting of positions..

Recent coverage has revealed the presence of a number of dams in
the Southeast China coastal area opposite Formosa. These dams appear.
to be constructed of earth and range in sizes of from 1300 feet to
200 feEt.
A total of ten dams have now been found in the Amoy area between
M,a-Chiang and the coast south of Amoy Island (See Enclosure 1). A
fifty foot wide irrigation ditch runs from the dam near Hsi-king to
Chao-kang via Chi-lu, Hou-ting and Hsin-hsu. The canal is being
engineered to carry water over the coastal plain between Tung-an and
Ta-ting Island. The largest reservoir appears to be at Hsi-keng,
north of Tung-an. The darns appear to be dual purpose dams, at the
present time, designed to provide for flood control and irrigation.
In the Hui-an area two dams and an irrigation canal have been
found. The canal is similar to the one in the Amoy area and travels
a twisting route from the dam located seven miles northwest of Hui-an
airfield, along the base of the hills to the west side of the airfield.
Recent coverage in the Shui-kou area revealed the presence of
four dams. Three of these sites are in a complex located four miles
north of the airfield and range in size from 2004 to 5004. A large

darn 1300 feet long is under construction approximately. twelve miles-
northeast of the airfield. This dam is 2504. wide at its base and has
a spillway measuring 604 wide and 1104 long, all under construction.
Eight miles northwest of Lung--tien airfield there are three dams,
the largest of which is 3804 across. In addition there are six to
eight smaller dams in the area. This system of dams forms a ring
about the base of sorie small hills with the three larger dams located
higher in the hills.
In all, a total of twenty-one dams have been located to date in
the area between Fu--chow and Shui-kou. These dams plus the irrigation
canals indicate that a large scale irrigation and flood control project
is underway in the area opposite Formosa.
