the
Station grounds. They grew well and showed very little killing back and
for several years gave quite nice crops of nuts, but of recent years the
yield has been rather small. The nut is blunt-oval in shape and of good
size with a fairly hard shell which is well sealed but not any too easy
to open. The quality is fairly good but the pellicle is rather strong
flavoured.

The year 1936 may be considered the high water mark in nut planting at
the Station. A variety block of filberts was set out that year and fifty
one-year-old Persian walnut seedlings (Carpathian strain) were planted
in a nursery row, and in permanent location in 1937. The filbert
planting consisted of from three to nine bushes each of twelve
varieties, including Aveline (white), Barcelona, Bixby, Bolwyller,
Buchanan, Cosford, Daviana, Du Chilly, Medium Long, Red Lambert (?) and
Jones hybrid. These were planted in a compact block, 18 feet apart each
way on the square. A lesser distance no doubt would be sufficient for
upright growing sorts like Du Chilly but some of the more spreading
kinds can use the greater distance.

Most of these filberts started to yield a few nuts at five to seven
years from planting and at nine or ten years were giving good crops.
Yields have fluctuated considerably from year to year, and also between
varieties and different bushes of the same variety. Yields obtained from
individual ten-year-old bushes and size of nut are given in the
following table.

Higher yields have undoubtedly been obtained from other plantations and
from other individual bushes and certainly lower yields, also, may be
expected. Those given above are for 1946 from the best ten-year-old
bushes in a plantation of forty plants.

Yield and size of nut while of major importance are not the only
criteria for appr
