Delving Into the History of the Cape Cod Canal

With the summer fast approaching, some of us will again create fond memories of our time on Cape Cod. The beaches, the waves, and the cool breezes remind us why we love the Cape. However, we do not have fond memories of the times spent waiting to cross the Sagamore and Bourne Bridges over the Cape Cod Canal to reach our destinations. The waiting can be an hour or more, especially on the weekends, and you may ask yourself, “Why do we have those bridges?” The history of those bridges is intrinsically linked to the Cape Cod Canal whose initial conception goes back to the 1800s. The State Library of Massachusetts has primary and secondary sources for both research and personal curiosity.

The concept of building the Cape Cod Canal started back to the late 1700s as described in an article from Cape Cod Magazine. The Massachusetts legislature began considering a canal as early as 1860 through House legislation prompted by the suggestion of Governor Nathaniel P. Banks. The author Clemens Herschel describes the early proposal and how it would affect the people living in the Canal area. The General Court’s Committee on Harbors and Public Lands had many sessions regarding the Canal as outlined in the book titled Hearing as to Incorporating the Bass River Canal Company from 1893 that provides an excellent history of what happened during those sessions.

The impetus for a Canal continued for decades with frustration mounting as discussed in the pamphlet  titled Cape Cod Canal. There were different proposals regarding the exact location of the Canal from Cape Cod Bay to Buzzards Bay. Hand drawn maps in the Special Collections Department illustrate those different approaches with examples including one map by the Massachusetts Commission on Waterways and Public Lands from 1917 showing one approach and the Massachusetts Board of Internal Improvement showing another very early approach.

Sagamore Bridge Construction

Since those times, several books have been written on the subject. One of the earliest was a book by George Everett Burbank in 1916 with more recent books including a book by William James Reid in 1961 and Robert H. Farson in 1993.

The State Library and its Special Collections Department have other resources for those interested in the history, issues, and construction of a major civil engineering project in Massachusetts. Search for materials in our library at www.mass.gov/lib or visit us during our hours of operation to delve into a fascinating and complex story.

Wrens Alight and Delight in the Library!

We're heading south this month, as we continue to commemorate the thirteen original colonies by displaying their state bird in our Audubon case. This month's print depicts the Great Carolina Wren (plate 78), which is South Carolina's state bird. But despite its name, the Carolina Wren has a large range and can be seen up and down the east coast.

Milder winters have contributed to the Carolina Wren venturing further north, and now you can spot these petite brown birds with a white stripe in both suburban landscapes and wilderness thickets here in Massachusetts. Read more and hear their call on the Mass Audubon website. And look closely at the wren at the top of this print, he looks like he is caught mid-call! 

We all know that "April showers bring May flowers" so in keeping with that theme for this month, this print was also selected for display because the Carolina Wren is shown in the vibrant flowering branches of the dwarf red buckeye (Aesculus pavia). Unfortunately, this shrub is native to the southern and eastern part of the country, so we aren't likely to see it here in Massachusetts. All the more reason to visit the library from May 12 through June 9 to see this print on display!

A CMR Adventure: Tracing the History of a Massachusetts Regulation

Last year we published a blog post titled Understanding the CMR. If you haven’t seen it yet, be sure to give it a read! That blog helps you understand what the CMR is and how it's organized. Now it’s time to go to the next level and learn how to research the history of a Massachusetts regulation. We wrote about this in 2013, but our collections have undergone some changes since then, so we thought it was time for an updated post.

With that in mind, let’s look at 105 CMR 125.004. Let’s say you’d like to see all the changes that regulation has gone through since 2015. We’ll trace the history of this regulation together.

To start, we’ll need to go to the Cumulative Tables. The Cumulative Tables, sometimes called “indexes,” are published in the final Massachusetts Register of each calendar year. The cumulative tables start in 1976 and continue through to the present. These tables document all regulation filings, including amendments, new regulations, and emergency regulations, published in the Register during that year.

You’ll find the Cumulative Tables in our digital repository. We also maintain a binder of Cumulative Tables from 1978 to the present, available in our Reading Room alongside the CMR. If you don’t know when a regulation was first added or when it was amended, you should begin by looking at the earliest Cumulative Table and work forward through each year. This helps you create a timeline of the regulation’s history.

As we mentioned, we want to see all the changes that 105 CMR 125.004 has gone through since 2015. We’ll start by looking at the Cumulative Tables file that includes 2015, using the Tables found in our digital repository.



Our digitized Cumulative Tables are keyword searchable, meaning you can do a “ctrl + F” search within the file for “105 CMR.” Each page of the Cumulative Tables is organized as follows:
  • Left-hand side: Agency title numbers (also called “digit title numbers”) in bold, with their chapter numbers listed beneath.
  • Right-hand side: Two columns showing
    1. The Register issue number where the regulation was published, and
    2. The effective date of the amendment or filing
From there, you’ll see if section 125 is listed. If it is, you’ll want to make note of the Register number and the effective date to use later. If it’s not included, it means that changes to that section did not take place that year.

For example, a page from the 2014-2025 year-end Cumulative Table shows there were amendments to 105 CMR during that time period. The first amendment for 105 CMR 125 appeared on 2/24/17. By noting the Register issue number (1333), you’ll know exactly where to look to find the full text of the change.


Once you’ve identified the relevant Register issue number, the next step is to look at that issue of Massachusetts Register. Each issue contains the text of the regulation as it was filed, allowing you to see exactly how the regulation appeared at that time. The State Library houses the complete set of Massachusetts Registers in print, and many issues are also available in our digital repository.

Hint: look for the Settings section on the left side of your screen. Set the “Sort By” to “Z→A.” This will sort the Registers from newest to oldest, making it easier for you to find the specific Register you need. In our example, you’ll want to look at Register 1201 through 1400. Next you’ll search for Register 1333 to see if sub-section .004 is listed.


You’ll want to repeat this process until you’ve traced the history of the regulation up through the year you’re interested in. You would keep looking through the Cumulative Tables for changes to 105 CMR 125, find the appropriate Register number, then check that Register to see if sub-section .004 is listed.

In our example, 105 CMR 125 was updated on the following dates, focusing only on the changes that have occurred since 2015 :

2/24/17 (Register 1333)

From there, we’d look in the Registers to see if sub-section .004 is listed. You can search for a specific Register by searching for “no. XXXX” in the Search bar above the list of Items. Here are our search results when we search for Register 1333 using that format:


By using the Cumulative Tables and the Massachusetts Registers together, you can trace how a regulation has evolved over time, whether it was newly created, amended, or repealed. While the process can be a bit tedious, these resources make it possible to construct the full history of a Massachusetts regulation.

Whether you are conducting legal research, exploring public policy, or just curious, the State Library’s collections and staff are here to help you navigate the CMR and its associated resources.

Explore the Coast and the Harbor Islands from a Bird’s-Eye View

In Boston, one of the markers that summer is on the horizon is the relaunching of the Boston Harbor Islands Ferry! To coincide with the spring schedule kicking off on May 15, we are displaying a 1905 map titled, "Bird’s Eye View of Boston Harbor and South Shore to Provincetown: Showing Steamboat Routes" in our Collections Spotlight case. This map prominently features Boston Harbor and the many islands found within, and also illustrates part of Boston, the South Shore, and Cape Cod from a bird's-eye perspective (not the cloudy view over parts of Boston, to emphasize that you are viewing it from above).


While this map has been unfolded and is currently stored flat, it originally would have been folded into a 4 inch by 8 inch rectangle partially affixed to a cardstock front and back cover. For preservation and access purposes, the covers have been removed and are normally stored in an acid-free paper sleeve in a folder along with the map. But this month, the cover is on display as a complement to the map. The cover features the title printed in an eye-catching font and informs us that the price was 10 cents (which would calculate to about $3.75 today, though maybe more if you were purchasing it from a touristy spot downtown!). It was published by John F. Murphy, a news agent and businessman who operated newsstands in railroad stations in the region, including South Station, where this map was likely sold. Also on display is a facsimile of the inside of the front cover, where an index to the map was printed. This is an especially useful resource as it indicates notable buildings and landmarks. For lighthouse fans, this map includes many, including Race Point Light (#32) jutting out from Cape Cod, Gurnet Light (#27) in Plymouth, and Boston Light (#23) in Boston Harbor. What’s missing from the list is Graves Light, also in Boston Harbor, as that lighthouse wasn’t constructed until 1905 and likely missed the publication date of this map.

Beyond lighthouses, there are many details to discover on this map. Note the numerous shipping routes leaving Boston, which could take you as close as Nantasket or as far as Europe. And the tourist-centered entries, like Hotel Pemberton (#18) at the end of Hull and the Myles Standish Monument (#28) in Duxbury. But one of the most interesting details is how many buildings are located on the Harbor Islands. Today, we generally consider recreation to be the Harbor Islands' primary function, but at the turn of the 20th century, they served a more utilitarian purpose. If you visit the islands today, you'll come across some foundations and building remnants that shed light on their past lives. Featured on this map are some of the following buildings: 
  • A farm school on Thompson’s Island (#6)
  • The City of Boston Almshouse and Hospital on Long Island (#9)
  • The City of Boston Quarantine Station on Gallop’s island (#14)
  • The City of Boston House of Reformation for Children on Rainsford Island (#16)
Also identified on the map are Fort Andrew (#17) on Peddocks Island and Fort Warren (#15) on George's Island, which exist as historical structures today.

We have previously highlighted a similar bird’s-eye view map that also shows the Harbor Islands and the eastern coastline from Boston to the Cape via the South Shore. This map is a bit more recent, published in 1920, and provides a more detailed view of Boston. You can check it out in this blog post and then compare it to the 1905 map, which is on display in our reading room from May 5 through June 2. Stop by to see it before you catch the ferry to the Harbor Islands!
