some specified rate. az at 8. 10 or 20
miles per hour, and at what rate the
force Is Increased with the Increase Of

when the velocity is doubled. the force Is
Increased to the sixth power Of the We
loclty. For instance, IL at a certain rate
OF velocity the force is sufficient to trans,

The force OF water or more correctly
the carrying power. or transmitting Ca
pacity of water varies as the squarespf
the velocity and the area OF tho exposed
surface and as the sixth power 81 the
velocity. If stream with a given Yclo-
city will transport pebbed Inch in
dlamcte rand Weighing one ounce, double
the velocity will transport q pebble four
inches In diameter and weighing q
ounces.
The usual accepted transporting capa-
city of streams is about as follows:
Mean velocity.
Clay fit for pottery. ......,..o5 feet per SEQ,
Sand ............... ..........05 feet per sec.
Gravel...... ......,... $500. S to1.5

Brand and Snan are forms OF the per-
feet participes Of the verbs burn and
spin, Brandnew is burnt-new-new from
the hre-now from the forge; and span
new is spun new-just from the distaff ors
possibly, tho loom.
These phrases originated among the ar-
tsans and spread upward, an Is commonly
tho case, until the use was general. Forge

garet uses the kindred form to Dorset in

1t is remarkable that so good a scholar
as Thomas Tyrwhltte is unable to explain
the perfectly natural lse In Chaucer's
Troilns and Cressde, book 3. line 1911,
We lind, "'rhis tale WAS aie span neue
to begin, etc." and Tyrwhitts note de-
cares, Span neue seems to slgnlne quito

Gualter or Walter Lynne was a scholar,
an author and n printer, he lived on Sons
mer's Key, near Bil!ingsgate, in London;
1t is said that he also kept a school at
the Eagle, next to st. Paul's school. All 3
HIS dated prints are from 1913 to 1850, He
appears to have had three undated books,
a catechsm, S, Augustine OH Predestina-
of Places or Law Our

these. ISnne's device was Ram, bear
