Matt with one of the sledges
he hand built during the long winter night while the
Roosevelt was trapped in the ice. Peary bought only raw
materials such as planks of hickory and straps of iron.
Matt worked as a carpenter to transform lumber into sledges
sturdy enough to carry hundreds of pounds of supplies over
many miles of rough sea ice. He had to repair damaged ones
as they went along, often in the 50 degree below zero
temperatures with stiff winds.
Here he is back from the Pole, probably posing for a
newspaper photographer.

| About images, pixels, and
resolution |
Web photos are standardized to 72
pixels/inch (px). This is like "dots per inch" only on a
monitor where each dot has a red, green, and blue phosphor
(pixels). All pictures on this site are at
the 72 px resolution. Format is JPEG usually set for maximum quality.
At 72 px/inch an image can be any width & height. Your
monitor just can't display more at one time than it's
setting--such as 800 pixels wide, 1024, 1140, 1600, etc. For
example: This photo is 72px resolution and 400px wide X
291px high.
Web pages are usually 800 pixels wide, although 640 pixels
is the maximum width of a printout of a webpage. That used
to be the limiting size of webpages, but now that people
have higher resolution monitors such as 1600 pixel wide LCDs
the trend is to larger images.
Print images are saved in TIFF format, with resolution of
300 dots/inch (DPI). At such high resolution one then
specifies size in inches. So a 300 dpi photo might be 5" x
7" or 8" x 10" , etc.
