of air-photo stratification. The Forestry Chronicle 37 (3): 338,
350-355. Dec. 1961.
A test of the efficiency of different systems of air photo
stratification was conducted in an area near the Petawawa Forest
Experiment Station. While stratification, particularly according
to cover type, height and canopy density, increased the precision
of the estimated total volume and mean annual increment, this increase
was not as large as had been expected. The main value of
air photo stratification may be in furnishing a forest type map
for management purposes.
No attempt was made to generalize from the results obtained.
They are applicable only to the particular forest where the test
was carried out,

1 J * 00 193-19^. 3 figs. I960.
The authors describe the so-called 'forkert budding' method,
used extensively for budding rubber (ifevea brasiliens^is). The
budding test on rubber was conducted at the Huey Tak. teak plantation
in northern Thailand. It was assumed that this method might also
be suitable for teak. Approximately 200 successful budygrafts were
made during the initial investigation. They were watched closely
during the first growth season and measured each month, and the
last record was made in December at the end of the rainy season.
Three buddings died owing to termites, but the rest had reached
an average height of 1.78. m. Some clones measured 2.68 m., and
were almost as high as the seedlings growing spontaneously in the
area surrounding the experimental plots.

The, Vietnamese are primarily a coastal an,", delta people, catchers
of fish and growers of rice. Their homes are among endless lagoons
and tidewater flats and dark, sluggish rivers, between whose
meaderings they lay out and till their paddies of rice with the intensity
and precision which that pampered crop demands. In historical
times, as their driftings can be traced along the western
rim of the South China Sea, they preferred to settle near the coast
and avoided the forbidding highland juiv.U es of the interior. While
rice paddies are troublesome to construct, they respond to attention
by producing some of the heaviest crops known to man. They demand
hard, monotonous physical labor. The lowland rice-growers have no
acquaintance with forests. Bamboo, earth and straw meet their needs
